Description

I. Technical Field

[0002] This invention relates to the fields of language acquisition systems, human-computer interaction, and smart terminal technology. Specifically, it relates to a multi-terminal system for target language acquisition that starts with auditory input and achieves immersive language acquisition by systematically organizing language input stages. It is suitable for long-term target language input scenarios where auditory input is the primary channel. II. Background Technology

[0004] Current language learning programs are mostly based on "explicit instruction," relying on one or more of the following methods:

[0005] • Text-first presentation of vocabulary or sentence structure;

[0006] Screen-driven human-computer interaction;

[0007] • Driven by clear teaching steps or learning tasks;

[0008] • Learning content switching triggered by user-initiated actions.

[0009] The above methods are applicable to adults or users with reading abilities, but they have significant limitations in the following scenarios:

[0010] 1. This product is intended for users who do not yet have text recognition capabilities;

[0011] 2. The learning environment is not the target language environment;

[0012] 3. The learning terminal is a wearable device without a screen or with low interactivity;

[0013] 4. The learning process needs to be carried out continuously and over a long period of time in everyday life scenarios.

[0014] Under the above conditions, systems based on text, explicit instruction, or strong interactive control are difficult to operate effectively.

[0015] One of the following is also lacking in the existing technology:

[0016] It is possible to do so without starting with a text or being guided by explicit teaching.

[0017] A system architecture for the phased organization, patterned scheduling, and state-based management of auditory input in the target language.

[0018] Therefore, it is necessary to propose a new target language acquisition system that does not start with text but organizes language input at the system level to solve the technical problems of long-term auditory input of the target language in terms of organization, stage evolution and input consistency.

[0019] III. Purpose of the Invention

[0020] The purpose of this invention is to provide a multi-stage language input system for immersive auditory acquisition of a target language, which achieves the following by uniformly managing auditory input content, input patterns, and language stage states:

[0021] • Focus on auditory input;

[0022] • Target language input under non-text-based starting conditions;

[0023] • Collaborative output under the premise of a clear distinction between the first language and the target language;

[0024] • In the absence of explicit instructional instructions, language input is scheduled in multiple stages.

[0025] The system provided by this invention does not limit the user's learning method or learning effect, but provides technical support for long-term and continuous auditory input of the target language through the input organization mechanism at the system level.

[0026] IV. Technical Solution

[0027] To achieve the above objectives, the present invention adopts the following technical solution:

[0028] A multi-stage language input system for immersive auditory acquisition of a target language includes:

[0029] • At least one second terminal;

[0030] • and the server with which it communicates;

[0031] In at least one embodiment, the system further includes:

[0032] • At least one first terminal.

[0033] System overall structure, such as Figure 1 As shown:

[0034] (a) Second terminal (the main terminal for language acquisition)

[0035] The second terminal is the main language acquisition terminal in the system, used to carry out the auditory language input process of the target user, and it must have at least the following:

[0036] • Voice playback capability;

[0037] • Voice acquisition capability;

[0038] • Network communication capabilities.

[0039] The second terminal can be a wearable terminal, a mobile terminal, or other devices suitable for long-term use, and whether or not it has a display screen is not a limiting condition.

[0040] During system operation, the second terminal is activated or participates in interaction according to the preset language input scenario, and is used to receive and play auditory input content in the target language.

[0041] (ii) First terminal (collaborative language input terminal, optional)

[0042] In at least one embodiment, the system further includes a first terminal.

[0043] The first terminal is an Auxiliary Language Input Terminal, which at least has the following features:

[0044] • Voice acquisition capability;

[0045] • Network communication capabilities.

[0046] The first terminal is used to collect external voice input and send the voice input to a server or a second terminal via a network to participate in the target language input process.

[0047] The existence of the first terminal does not constitute a necessary condition for the system to operate.

[0048] () server

[0049] The server is used to perform the following functions:

[0050] • Manage the user's language stage status;

[0051] • Differentiate between the first language and the target language when inputting the language;

[0052] • Based on the language stage state, organize and control the auditory language content output to the second terminal.

[0053] Core functional modules:

[0054] 1. Auditory Input Module

[0055] It is used to generate, receive, or schedule auditory input content in a target language, and output the content in speech form to a second terminal, characterized in that:

[0056] The auditory input content is output in audio format;

[0057] • In the initial stage of the system, no text information corresponding to the auditory input is presented to the user;

[0058] The auditory input content is at least distinguished as follows:

[0059] First language related input;

[0060] Target language related input.

[0061] The auditory input module can selectively output according to system instructions:

[0062] • Contains only audio content in the target language;

[0063] • Target language audio content including first language semantic aids;

[0064] • Target language audio content with different speaking speeds and speaker characteristics.

[0065] The auditory input can be derived from:

[0066] • Pre-stored language materials;

[0067] • Voice input collected by the first terminal;

[0068] • Voice content generated or processed by the server.

[0069] 2. Mode control module

[0070] Used to control the system to operate in different language input modes, such as Figure 2 As shown, the feature is:

[0071] Abstract the system's operating state into at least one language input mode;

[0072] The language input mode is used to define:

[0073] • Current input source;

[0074] • Input language type;

[0075] • Output relationship between the first language and the target language.

[0076] The language input modes include, but are not limited to:

[0077] • One-way target language input mode;

[0078] • Input patterns that follow the first language to the target language;

[0079] • A bidirectional associative input mode between the target language and the first language.

[0080] The mode control module controls the switching between different language input modes based on preset conditions or real-time status signals.

[0081] The system supports a "Semantic Scaffolding" mode. In this mode, the system uses the first language as a temporary carrier to fill in the context of complex word blocks in the target language in a "non-translational" manner. The frequency of the first language intervention is strictly controlled by the state management module, and the first language will automatically withdraw as the evolution state improves.

[0082] The system supports an asymmetric assistance mechanism. When the system detects that the complexity C of the target language payload at the current stage exceeds the user's current absorption threshold T, it automatically intersperses extremely low-frequency semantic anchor audio with first-language features into the main payload based on asynchronous scheduling principles. This intervention is precisely controlled by the weight decay of the state machine, aiming to maintain immersion while providing the necessary cognitive scaffolding.

[0083] 3. Language Stage Status Management Module

[0084] Used to maintain the language stage state of the target user, such as Figure 3 As shown, the feature is:

[0085] • Divide the target language input process into multiple stages;

[0086] • Different input strategies and pattern combinations correspond to different stages of the state;

[0087] • Changes in stage status do not depend on the user's recognition or manipulation of text content.

[0088] The language stage status management module can update the stage status based on at least one of the following information:

[0089] • The cumulative number of auditory inputs;

[0090] • Repeated exposure of specific audio content;

[0091] System uptime;

[0092] • Status feedback from the mode control module.

[0093] 4. The mechanism for distinguishing between the first language and the target language

[0094] In this system: the first language is used to assist in system control or semantic triggering; the target language serves as the primary auditory input.

[0095] The system ensures, through module-level control, that:

[0096] • The target language is always used as the primary output language;

[0097] • The first language is not presented as text or the primary subject of learning;

[0098] • The intervention of the first language is jointly constrained by the pattern control module and the stage state management module.

[0099] This system employs "implicit structure alignment technology" to simultaneously maintain a "quasi-text feature sequence" in the background while outputting auditory content. Although this sequence is not initially displayed to the user, it ensures that each piece of auditory input possesses extremely high textual traceability. When the user enters the "symbol mapping preparation stage," the system can directly invoke this sequence, achieving instantaneous activation from sound to text, avoiding the problem of relearning symbols later.

[0100] Input organization principles (non-instructional features)

[0101] The operation of this system follows these principles:

[0102] • Do not use text as the starting form for language input;

[0103] • No explicit understanding, memorization, or feedback is required from the user;

[0104] • Prepare for language acquisition through continuous, phased auditory input.

[0105] In at least one implementation, the system does not provide language prompts in text form during a specific language stage.

[0106] System operation method flow

[0107] Method Implementation Examples (Illustrative Writing)

[0108] like Figure 7 As shown, the present invention provides a method for operating a language input system, comprising the following steps:

[0109] S01, Initialize the language stage state, which is used to characterize the current stage of the target language input and is associated with at least one user or a second terminal.

[0110] S02, receiving at least one input trigger signal, the input trigger signal coming from a first terminal or a second terminal, and including at least one of voice input, behavior input, time trigger or environment trigger.

[0111] S03, determine the current language stage based on the stored language stage status.

[0112] S04. Based on the current language stage state, organize the auditory input of the target language. The organization includes the selection, combination or adjustment of the auditory input content, and does not depend on the text presentation.

[0113] S05, the organized target language auditory input is sent to the second terminal for playback.

[0114] S06, Update the language stage state based on at least one factor during system operation.

[0115] S07, return to step S02, or maintain the current language stage state to continue running the language input system.

[0116] V. Beneficial Effects

[0117] Compared with the prior art, the present invention has at least the following technical effects:

[0118] 1. Organize auditory input of the target language at the system level rather than the teaching level, and avoid using explicit teaching or text presentation as the starting condition for language input;

[0119] 2. Through the language stage state management mechanism, the target language input has long-term continuity, structural consistency and stage adaptability, thereby forming a stable and low-interference language input environment;

[0120] 3. Through a pattern control mechanism, asymmetric collaborative output between the input language and the target language is achieved to adapt to different language relationships and usage scenarios;

[0121] 4. Supports multi-terminal collaborative operation without relying on a specific terminal form, and can adapt to terminal application scenarios without screens or with low interaction capabilities.

[0122] 5. Possesses excellent system scalability, adaptable to different language combinations and usage environments, and reserves system interfaces for future language capability evolution and other forms of language presentation, such as... Figure 6 As shown.

[0123] In this invention, language input is no longer regarded as a discrete teaching behavior, but as a continuous input process that is uniformly organized and scheduled by the system.

[0124] Through the language stage state management module, the system can maintain the consistency of target language input in terms of content complexity, input frequency and input format at different stages, thereby avoiding the input fragmentation problem caused by frequent mode switching in traditional language learning systems.

[0125] Meanwhile, the mode control module enables the system to flexibly organize unidirectional or multidirectional auditory input based on the relationship between the input language and the target language, without relying on text display or explicit user interaction.

[0126] Because the system does not depend on a specific terminal form, it can naturally adapt to screenless, low-interaction, or wearable terminals, and provides room for expansion for the subsequent introduction of other language presentation forms. Attached Figure Description

[0136] The present invention will be further illustrated below with reference to examples, but should not be construed as limiting the scope of protection of the present invention.

[0137] Method Implementation Examples:

[0138] Example 1: An example of a basic system for immersive auditory input of a target language

[0139] In this embodiment, a multi-stage language input system for immersive auditory acquisition of a target language is provided, which is the minimum system configuration capable of implementing the technical solution of the present invention.

[0140] The system includes:

[0141] A second terminal and a server that is communicatively connected to the second terminal.

[0142] Second terminal:

[0143] The second terminal has the following functional capabilities:

[0144] • Voice playback capability, used to output auditory language content;

[0145] • Network communication capabilities, used for data interaction with servers.

[0146] In this embodiment, whether the second terminal has voice acquisition or display capabilities is not a limiting condition; its core function is to receive and play the target language auditory input content provided by the server.

[0147] server

[0148] The server includes:

[0149] 1) Auditory input module

[0150] • Used to generate, schedule, or acquire auditory input content in the target language;

[0151] 2) Language Stage Status Management Module

[0152] Used to maintain the current language stage state of the target user, the language stage state is used to reflect at least the stage differences in content complexity, structural form or input frequency of the target language input;

[0153] 3) Mode control module

[0154] Used to control the system to operate in at least one language input organization mode based on the language stage state.

[0155] System operation mode

[0156] During system operation, the server retrieves the target language auditory content matching the current stage from the auditory input module based on the language stage status it maintains, and sends it to the second terminal via the network, where it is played back in voice format.

[0157] In this embodiment, the target language auditory input is not in text form as a starting condition, and the system does not require the user to perform explicit operations or feedback.

[0158] Through the above structure, this embodiment realizes a basic system closed loop that relies solely on auditory input and organizes target language input through stage state management.

[0159] Example 2: An Example of a Multi-Terminal Language Input System Including a Collaborative Input Terminal

[0160] In this embodiment, based on the system structure described in Embodiment 1, a multi-terminal collaborative language input system including a first terminal is further provided, such as... Figure 4 As shown.

[0161] The system includes:

[0162] A second terminal, a server, and at least one first terminal.

[0163] First Terminal

[0164] The first terminal is a collaborative language input terminal, which at least has:

[0165] • Voice acquisition capability;

[0166] • Network communication capabilities.

[0167] The first terminal is used to collect external voice input and send the voice input to the server.

[0168] System operation mode

[0169] During system operation, the server receives voice input from the first terminal and performs at least one of the following processing operations based on the voice input:

[0170] • Perform language type recognition on the voice input;

[0171] • Determine the linguistic relationship between the voice input and the target language;

[0172] • Generate, transform, or schedule the target language auditory input content based on the current language stage status.

[0173] After processing, the server sends the organized target language auditory input to the second terminal for playback.

[0174] Technical Features Description

[0175] In this embodiment:

[0176] The existence of the first terminal serves to enrich the sources of auditory input for the target language;

[0177] The first terminal does not constitute a necessary condition for the operation of the system;

[0178] The system does not require a fixed role relationship between the first terminal and the second terminal.

[0179] Through the above structure, this embodiment realizes a multi-terminal language input system that supports external collaborative input but still has the server uniformly organizing the language input stage.

[0180] Example 3: An Example of a Language Input System Adapted to Screenless or Non-Text Output Terminals

[0181] In this embodiment, a target language immersive auditory input system adapted to screenless or non-text output terminals is provided.

[0182] The overall structure of the system is the same as that of the system described in Embodiment 1 or Embodiment 2, the difference being the capability configuration of the second terminal and the system output method.

[0183] Second terminal

[0184] In this embodiment, the second terminal is a terminal that does not have display capabilities or whose display capabilities are not enabled, and it has at least the following features:

[0185] • Voice playback capability;

[0186] • Network communication capabilities.

[0187] During system operation, the second terminal is not used to present text, graphics or other visual language prompts; the language input content provided by the server to the second terminal is only output in auditory form.

[0188] System operation mode

[0189] Based on the stage status maintained by the language stage status management module, the server retrieves the target language auditory input content that matches the current stage from the auditory input module and sends it to the second terminal via the network.

[0190] After receiving the target language auditory input, the second terminal plays it as a voice without providing any text-based language prompts at the same time or afterwards.

[0191] Technical Effect Description

[0192] By limiting language input to auditory form, this embodiment enables the system to:

[0193] It can run continuously without a screen.

[0194] Avoid users relying on text for language understanding;

[0195] Ensure that the target language input is organized and presented through a unified auditory channel.

[0196] Through the above method, this embodiment realizes a system implementation method for organizing target language auditory input under non-text display conditions.

[0197] Example 4: An Example of a Low-Interaction or Passive Participation Language Input System

[0198] In this embodiment, a low-interaction language input system that does not rely on active user operation is provided for immersive auditory input of the target language.

[0199] The overall structure of the system is the same as the aforementioned embodiments, the difference being in the system triggering mechanism and user participation method.

[0200] System triggering method

[0201] In this embodiment, during operation, the system does not require the user of the second terminal to perform at least one of the following operations:

[0202] • Actively select the language input content;

[0203] • Proactively initiate a language input request;

[0204] • Provide explicit confirmation of the language input results.

[0205] The system automatically organizes and outputs auditory input of the target language based on preset trigger conditions.

[0206] The triggering condition includes at least one of the following:

[0207] • Time-triggered conditions;

[0208] • Scene or environment-related triggering conditions;

[0209] • Input rhythm control conditions related to language stage state.

[0210] System operation mode

[0211] When the triggering condition is met, the server schedules the corresponding target language auditory input content from the auditory input module according to the current language stage status and sends it to the second terminal for playback.

[0212] During this process, the system does not require the correctness of user behavior to be judged, nor does it rely on user feedback to make real-time adjustments to the language stage status.

[0213] Technical Effect Description

[0214] Through the above design, this embodiment enables the system to:

[0215] • Long-term operation under low-intervention conditions;

[0216] • Reduce the interactive burden during language input;

[0217] • Maintain the continuity and structural consistency of the target language input.

[0218] Through the above methods, this embodiment realizes an implementation of a target language auditory input system suitable for passive participation or low-interaction scenarios.

[0219] Example 5: An Example of a Language Input System Based on Gradual Changes in Language Stage States

[0220] In this embodiment, a target language auditory input system based on the gradual change of language stage state is provided to illustrate the specific function of the language stage state management module during system operation.

[0221] Setting the language stage state

[0222] In this embodiment, the server maintains at least two different language stage states for the target user. The different language stage states are used to define the characteristics of the target language auditory input in at least one of the following aspects:

[0223] • The structural complexity of the input content;

[0224] • The length or combination of the input content;

[0225] • Input content's speaking speed, rhythm, or repetition strategy.

[0226] The different stages of language development are not isolated from each other, but are organized according to a pre-set stage sequence or evolutionary relationship.

[0227] System operation mode

[0228] During operation, the system selects target language auditory input content that matches the current language stage from the auditory input module and outputs it to the second terminal, based on the current language stage status.

[0229] When the preset stage evolution conditions are met, the server updates the target user's language stage state and applies the updated stage state during subsequent language input.

[0230] The stage evolution conditions may include at least one of the following:

[0231] • Preset time accumulation conditions;

[0232] • The cumulative conditions for language input exposure;

[0233] • Conditions related to the system's operating cycle.

[0234] Technical Effect Description

[0235] In this way, this embodiment enables the auditory input of the target language to exhibit progressive characteristics as the language stage changes, without requiring explicit user participation or understanding of the stage change rules.

[0236] Through the language stage state management module, the system can maintain the consistency and continuity of the target language input in terms of structure and complexity during long-term operation.

[0237] Example 6: An example of a language input system where the input language and the target language are inconsistent.

[0238] In this embodiment, a target language auditory input system is provided where the input language is different from the target language. Figure 5 The diagram illustrates how the system operates under multilingual input conditions.

[0239] Distinguishing between input language and target language

[0240] In this embodiment, the voice input language received by the system is different from the target language.

[0241] After receiving the voice input in the input language, the server performs language type recognition or language relationship judgment to determine the language difference relationship between the input language and the target language.

[0242] Generation and organization of auditory input content

[0243] After determining that the input language is inconsistent with the target language, the server generates, converts, or selects the corresponding target language auditory input content based on the input language.

[0244] The generation or conversion process is not limited to word-for-word translation, and may include at least one of the following methods:

[0245] • Semantic-based language content generation;

[0246] • The input content is simplified or reconstructed to generate the target language expression;

[0247] • Select auditory content that is relevant to the input semantics from pre-stored target language materials.

[0248] The generated target language auditory input content is further constrained by the current language stage state to ensure that it conforms to the stage-specific input characteristics.

[0249] System operation mode

[0250] The server sends the organized target language auditory input to the second terminal for playback.

[0251] In this embodiment, the language stage state management module works in conjunction with the generation or conversion process to ensure that the target language input maintains a consistent input structure at different stages.

[0252] Technical Effect Description

[0253] Through the above method, this embodiment enables the system to organize the auditory input of the target language in a unified, phased manner even when the input language and the target language are inconsistent.

[0254] This embodiment further demonstrates that the core of the system lies in the stage management and organization mechanism of language input, rather than the specific language conversion method.

[0255] Example 7: An Example of a Target Language Auditory Input System Where the Input Language is the Same as the Target Language

[0256] In this embodiment, a target language auditory input system in which the input language is consistent with the target language is provided to illustrate the operation mode when the system does not involve language conversion or translation.

[0257] Input language conditions

[0258] In this embodiment, the voice input language collected by the first terminal or the second terminal is consistent with the target language.

[0259] Upon receiving the voice input, the server may perform at least one of the following processing methods:

[0260] • Recognize speech content to obtain semantic information;

[0261] • Perform linguistic feature analysis on the speech content;

[0262] • Use voice input as a trigger signal rather than a content source.

[0263] Organization of auditory input

[0264] When the input language is the same as the target language, the system does not process the speech input for the purpose of "correction", "explanation" or "teaching". Instead, it organizes the target language auditory input content that is related to or unrelated to the input according to the current language stage.

[0265] The target language auditory input content may include at least one of the following:

[0266] • Repetition, variation, or reorganization of the input speech;

[0267] • Target language auditory materials related to the input semantics;

[0268] • Target language input that has no direct semantic correspondence with the input but conforms to the current language stage.

[0269] System operation mode

[0270] The server, based on the language stage state management module, selects and organizes the target language auditory input and sends it to the second terminal for playback.

[0271] During this process, the system does not require users to make explicit responses, does not provide explicit feedback, and does not present any text information.

[0272] Technical Effect Description

[0273] Through the above method, this embodiment demonstrates that even when the input language is consistent with the target language, the system still operates with a staged auditory input organization as its core operating mechanism.

[0274] This embodiment further illustrates that the system does not rely on translation or cross-language conversion behavior, but operates independently of language type, thereby avoiding the system's function being limited to translation or language teaching systems.

[0275] Example 8: An Example of a Language Input System Supporting Language Capability Evolution and System Expansion

[0276] In this embodiment, a target language auditory input system that supports language ability evolution and system expansion is provided to illustrate how the system operates at different language ability stages and in future expansion scenarios.

[0277] System expansion interface settings

[0278] In this embodiment, without changing the core language stage state management mechanism, the system reserves at least one extended interface to support different forms of language presentation or interaction methods.

[0279] The extended interface can be used to access at least one of the following modules:

[0280] Other forms of language output modules;

[0281] Other types of terminal equipment;

[0282] • Additional input or perception modules related to the target language.

[0283] Language ability evolution process

[0284] In the early stages of system operation, the system primarily uses auditory input of the target language as the sole or main method of language presentation.

[0285] As the language stage state changes, the system can gradually introduce other forms of language presentation without changing the original operating logic. Whether and when the presentation mode is enabled is controlled by the language stage state management module.

[0286] The extended interface supports access to physical environment-aware data (such as geographic location and object recognition). In the advanced evolution stage, the system can dynamically generate a target language input stream with spatial logic that matches the user's real physical world, thereby constructing a "language-driven digital twin world".

[0287] System operation principles

[0288] In this embodiment, regardless of whether the system introduces a new language presentation format, the following principles remain unchanged:

[0289] The system does not aim at explicit instruction;

[0290] • Language input is always organized based on stage status;

[0291] Users do not need to understand or operate the language stage rules.

[0292] Technical Effect Description

[0293] Through the above methods, this embodiment enables the system to support the long-term evolution of target language capabilities while maintaining the stability of the core technical solution.

[0294] This embodiment provides a technical foundation for the extended application of the system in different language pairs, different usage scenarios and different terminal forms, while avoiding narrowing the scope of patent protection by limiting specific interaction forms.
