Description

Technical Field

[0001] This application relates to the field of communications, specifically to an audio transcription device. Background Technology

[0002] In existing technologies, users often need to save real-time voice communication or voice messages sent through mobile applications as audio files in a universal format. However, current implementation faces the following major technical challenges: First, various applications on different operating systems typically use proprietary audio encoding and encapsulation formats, resulting in saved voice files that cannot be recognized and played by universal players. Second, these audio files often have randomly generated filenames that lack effective identification, making it difficult for users to quickly locate the target file for export. Furthermore, due to privacy restrictions imposed by applications and the fact that mobile operating systems typically do not grant ordinary users access to internal audio stream recording permissions, achieving "playback and recording simultaneously" via system recording is technically difficult or has an excessively high operational barrier. These issues collectively hinder users' ability to effectively export, store, manage, and use voice data.

[0003] A common solution is to play audio on a mobile phone, then connect it to a transcription device via a 3.5mm audio cable using an adapter, and then use a host computer to transcribe it into an audio file. However, this method results in low audio quality because the digital signal undergoes multiple analog-to-digital conversions and transmissions. It also carries circuit noise, which manifests as a relatively low maximum cross-correlation coefficient, significantly impacting the accuracy of voiceprint information. Utility Model Content

[0004] In view of this, it is necessary to provide an audio transcription device that can improve the ease of use of the audio transcription device while reducing the noise and audio distortion generated during audio transcription.

[0005] To achieve the aforementioned technical effects, in a first aspect, this application provides an audio transcription device, comprising: Several different types of audio input interfaces, each type of audio input interface being used to connect to different types of audio input devices; Several different types of audio output interfaces, the different types of audio output interfaces being used to connect to different types of audio storage devices; An audio processor is configured to receive different types of audio signals from different types of audio input devices and input the different types of audio signals into an audio storage device via different types of audio output interfaces.

[0006] In one possible embodiment, it further includes: A monitoring interface is provided for connecting to an audio playback device, which is used to play the audio signal.

[0007] By setting up a monitoring interface, audio signals can be played, making it easier for users to confirm audio signals or directly obtain information from them.

[0008] In one possible embodiment, it further includes: A volume indicator light group consisting of several indicator lights, wherein the number of indicator lights lit is determined according to the degree to which the audio signal is close to clipping.

[0009] By setting up a volume indicator light group, users can more easily monitor the volume of the audio signal and the degree of near-clipping.

[0010] In one possible embodiment, the plurality of different types of audio input interfaces include at least two of the following: a Type-C interface, a Bluetooth transmission interface, a recording interface, and an AUX interface.

[0011] In one possible embodiment, it further includes: A transcription mode switching switch, wherein the transcription mode switching switch includes a unidirectional transcription state and a bidirectional transcription state; When the transcription mode switching switch is in unidirectional transcription state, the audio processor will input the audio signal received from any of the audio input interfaces into the audio storage device; When the transcription mode switch is in bidirectional transcription mode, the audio processor merges the audio signal input from the recording interface with the audio signal input from any one of the Type-C interface, the Bluetooth transmission interface, and the AUX interface, and then inputs it into the audio storage device.

[0012] By setting a transcription mode switching switch, the function can be switched between single-audio signal transcription and multi-audio signal transcription, thereby adapting to different application scenarios and further expanding the applicability of the audio transcription device.

[0013] In one possible embodiment, the various types of audio output interfaces include a Type-C interface and a memory card interface.

[0014] In one possible embodiment, when the audio input interface includes a Type-C interface and / or the audio output interface includes a Type-C interface, the Type-C interface includes a charging pin.

[0015] The audio transcribing device can be charged directly via a Type-C audio output interface by setting a charging pin.

[0016] In one possible embodiment, it further includes: a plurality of status indicator lights, each of the plurality of indicator lights being either lit or off when each of the audio input interfaces and each of the audio output interfaces is in a connected state or a disconnected state.

[0017] By setting status indicator lights for each audio input interface and each audio output interface, it is easier to monitor the connection status of each audio input interface and each audio output interface.

[0018] In one possible embodiment, it further includes: an automatic gain switch; When the automatic gain switch is turned on, the audio processor adjusts the transcription gain according to the volume of the audio signal.

[0019] In one possible embodiment, it further includes a power interface for connecting an external power source to power the audio transcription device.

[0020] The beneficial effects of this application are: Compared with related technologies, the audio transcription device provided in this application is equipped with several different types of audio input interfaces and several different types of audio output interfaces. In use, audio input devices with different types of interfaces can be connected to the same type of audio input interface, and audio storage devices with different types of interfaces can be connected to the same type of audio output interface. This eliminates the need for additional configuration interface converters or adapters, improving the ease of use of the audio transcription device. At the same time, since the audio processor can directly receive different types of audio signals from the different types of audio input devices and input the different types of audio signals into the audio storage device through the different types of audio output interfaces, there is no need to perform analog-to-digital conversion on the audio signals, thereby achieving lossless transcription of audio signals and reducing noise and audio distortion generated during audio transcription.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] In the description of the embodiments of this application, unless otherwise stated, "several" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0025] The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a technical feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] Please refer to Figure 1 This application provides an audio transcription device, including: several different types of audio input interfaces 100 (specifically including such as...). Figure 1 The interface includes a Type-C interface 101, a Bluetooth transmission interface 102, a recording interface 103, and an AUX interface 104, and several different types of audio output interfaces 200 (specifically including, for example, Figure 1The system includes a Type-C interface 201, a memory card interface 202, and an audio processor 300. Different types of audio input interfaces are used to connect to different types of audio input devices. For example, a Type-C audio input interface 100 can be used to connect to a Type-C interface audio input device, and an AUX interface audio input interface 100 can be used to connect to an AUX interface audio input device. Different types of audio output interfaces are used to connect to different types of audio storage devices. For example, a Type-C audio output interface 200 can be used to connect to a Type-C interface host computer, and a memory card interface audio output interface 200 can be used to connect to a memory card. The audio processor 300 receives different types of audio signals from the different types of audio input devices 100 and inputs these different types of audio signals to the audio storage device via the different types of audio output interfaces 200. For example, the audio processor 300 can directly store the audio signals to a memory card, or input them to the host computer via a Type-C interface audio output interface through a communication protocol such as USB Audio Class (UAC).

[0028] It is understandable that, such as Figure 1 The various types of audio input interfaces 100 shown specifically include a Type-C interface 101, a Bluetooth transmission interface 102, a recording interface 103, and an AUX interface 104. These are merely illustrative examples of different types of audio input interfaces 100 in this embodiment. In some other embodiments of this application, the various types of audio input interfaces 100 may include only some of these types, and the specific configuration can be tailored to actual needs. Similarly, as... Figure 1 The several different types of audio output interfaces 200 shown include a Type-C interface 201 and a memory card interface 202. These are only specific examples of several different types of audio output interfaces 200 in this embodiment. In some other embodiments of this application, the several different types of audio output interfaces 200 may include only some of them. The specific configuration can be set according to actual needs.

[0029] Compared with related technologies, the audio transcription device provided in this embodiment is provided with several different types of audio input interfaces 100 and several different types of audio output interfaces 200. In use, audio input devices with different types of interfaces can be connected to the same type of audio input interface 100, and audio storage devices with different types of interfaces can be connected to the same type of audio output interface 200. Therefore, there is no need to use additional configuration interface converters or adapters, which improves the ease of use of the audio transcription device. At the same time, since the audio processor 300 can directly receive different types of audio signals from the different types of audio input devices and input the different types of audio signals into the audio storage device through the different types of audio output interfaces 200, there is no need to perform analog-to-digital conversion on the audio signals, thereby achieving lossless transcription of audio signals and reducing noise and audio distortion generated during audio transcription.

[0030] Please refer to Figure 2 In some embodiments of this application, the audio transcription device further includes a transcription mode switching switch 400, which includes a unidirectional transcription state and a bidirectional transcription state. When the transcription mode switching switch 400 is in the unidirectional transcription state, the audio processor 300 inputs the audio signal received from any of the audio input devices 100 into the audio storage device. When the transcription mode switching switch 400 is in the bidirectional transcription state, the audio processor 300 inputs the combined audio signals received from any two of the audio input devices into the audio storage device.

[0031] In this embodiment, when the transcription mode switching switch 400 is in bidirectional transcription mode, the audio processor 300 can simultaneously acquire audio data from any of the following audio input interfaces: Type-C, Bluetooth, and AUX, and the recording interface (i.e., recording interface 103). The two types of audio data are then merged and input into the audio storage device. By setting the transcription mode switching switch 400, switching between single-audio signal transcription and multi-audio signal transcription functions can be achieved, thereby adapting to different application scenarios and further expanding the applicability of the audio transcription device.

[0032] Please refer to Figure 3 In some embodiments of this application, the audio transcription device further includes a monitoring interface 500, which can be connected to an audio playback device. The audio processor 300 can also input the audio signal received from the audio input interface into the audio playback device for playback via the monitoring interface 500. By setting the monitoring interface 500, the audio signal can be played, making it easier for users to confirm the audio signal or directly obtain information from the audio signal.

[0033] In some embodiments of this application, the number of listening interfaces 500 can be multiple, and the multiple listening interfaces 500 can be used to connect different audio playback devices so that multiple different people can listen to the audio signal transmission. For example Figure 3 As shown, there are two monitoring interfaces 500 (i.e., interface 501 and interface 502). During a call between person A and person B, the audio signal received from the audio input interface can specifically include the audio signal sent by person A to person B. The audio signal sent by person A to person B can be played back to person B through one of the interfaces 501. Person B's voice can be recorded by the recording interface 103, converted into an audio signal, and sent back to person A, thus completing the call between person A and person B. During this process, person C can monitor person A's call through interface 502.

[0034] Please refer to Figure 4 In embodiments of this application, the audio transcription device further includes a volume indicator light group 600 composed of several indicator lights. The volume indicator light group 600 determines the number of indicator lights illuminated based on the degree to which the audio signal is close to clipping. For example, the volume indicator light group 600 includes 10 volume indicator lights. When the input signal is normal, lights 1-7 illuminate according to the volume percentage of the input signal. When the input signal is close to clipping, lights 1-9 illuminate. When the input signal has reached the point of clipping, lights 1-10 are all illuminated. By setting the volume indicator light group 600, it is easier for users to monitor the volume of the audio signal and the degree to which it is close to clipping. Furthermore, the volume indicator lights can be set to different colors, for example, lights 1-7 can be green, lights 8-9 can be yellow, and light 10 can be red.

[0035] In embodiments of this application, when several different types of audio input interfaces 100 include Type-C audio input interfaces and / or several different types of audio output interfaces 200 include Type-C audio output interfaces, the Type-C audio input interfaces and / or Type-C audio output interfaces specifically include charging pins. By providing charging pins, the battery built into the audio transcription device can be charged directly via the Type-C audio output interface.

[0036] It is understood that the aforementioned setting of charging pins in Type-C audio input and / or Type-C audio output interfaces is merely an illustrative example of one embodiment of this application and is not the only setting method. For other embodiments of this application, please refer to... Figure 1 , Figure 2 , Figure 3 as well as Figure 4 Alternatively, a power interface 700 can be directly provided, which supplies power to the audio transcription device by connecting to an external power source.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The audio transcription device also includes several status indicator lights 800, each corresponding to a specific audio input interface and an audio output interface. Each indicator light 800 is illuminated when the audio input interface and audio output interface are connected, and is off when they are disconnected. By assigning status indicator lights 800 to each audio input interface and audio output interface, the connection status of each audio input interface and audio output interface can be monitored more easily.

[0038] Please refer to Figure 5 The audio transcription device also includes an automatic gain switch 900. When the automatic gain switch 900 is in the on state, the audio processor 300 adjusts the transcription gain according to the volume of the audio signal. By setting the automatic gain switch 900, the audio gain function can be directly switched on and off, further expanding the application scenarios of the audio transcription device.

[0039] The audio transcription device provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
