Description

[0001] This application is a divisional application of invention patent 2022104034904 filed on April 21, 2022 Technical Field

[0002] The present invention belongs to the field of speech recognition technology, and in particular relates to a method, system and electronic device for identifying and displaying a key subsequence of a speech sequence, and a storage medium for implementing the method. Background Art

[0003] With the advancement of artificial intelligence (AI) and the widespread adoption of smart devices, mobile devices and other devices are providing features such as meeting voice recording recognition, recording text conversion, and archiving and indexing key meetings. These features have greatly met the need for voice recording and text conversion. Today, voice navigation, voice wakeup, voice dialing, and voice-to-text conversion have become popular across various devices. Intelligent voice control has evolved from a simple, playful application used out of boredom to a truly practical, user-friendly application. Intelligent voice applications are maturing, and the terminal industry is ushering in a new revolution featuring intelligent voice control.

[0004] For example, the Chinese invention patent CN202111600180.3 under review proposes a voice information processing method that can realize voice-to-text conversion without sending voice messages to customers or protecting the personal privacy of voice messages, thereby ensuring the security of information interaction in real-time chat programs.

[0005] However, the inventors discovered that while most existing real-time speech translation engines can achieve real-time recognition of continuous audio streams, recognize and translate the content of voice input in real time, convert it into text information, and return the corresponding text stream, in certain special situations, especially those involving specific vocabulary and vocabulary in specific formats, such as in voice communication in the fields of chemistry and molecular biology, the speech sequence often contains a large amount of specialized chemical vocabulary. The existing word-by-word and sentence-by-sentence speech-to-text translation method fails to highlight the key subsequences in these speech sequences, making it difficult for both parties in the voice interaction to quickly and accurately absorb the key content, thus affecting the efficiency of voice communication. Summary of the Invention

[0006] To solve the above technical problems, the present invention proposes a method, system, and electronic device for identifying and displaying key subsequences of a speech sequence, as well as a storage medium for implementing the method.

[0007] In a first aspect of the present invention, a method for identifying and displaying a key subsequence of a speech sequence is provided, the method comprising the following steps:

[0008] S100: Acquire a speech sequence;

[0009] S200: Identify whether there is a key subsequence in the speech sequence;

[0010] If so, the emphasized subsequence is displayed in a predetermined format while playing the speech sequence;

[0011] If it does not exist, play the voice sequence directly;

[0012] The focus subsequence includes a reaction relationship of at least one chemical substance and / or chemical substance combination;

[0013] Displaying the key subsequence in a predetermined format includes displaying at least one chemical formula corresponding to the at least one chemical substance and / or a chemical reaction formula, a chemical molecular formula, an electronic structure formula of the chemical substances, etc. corresponding to the chemical substance combination as a picture.

[0014] As the implementation basis of the solution of the present invention, the speech sequence obtained in step S100 includes multiple pause points;

[0015] After step S100 and before step S200, the method further includes the following steps:

[0016] The speech sequence is divided into a plurality of speech subsequences based on the pause points.

[0017] At the same time, in order to ensure real-time performance and accuracy, save system process resources, and ensure the adaptability of the process and the processing procedure, step S100 further includes:

[0018] After acquiring the speech sequence, determining a first number of pause points included in the speech sequence;

[0019] activating a second number of focused subsequence identification processes;

[0020] As a specific implementation method, step S200 includes the following sub-steps:

[0021] S201: Identify the current pause point in the acquired speech sequence;

[0022] S202: Translate the speech subsequence before the current pause point into a text subsequence;

[0023] S203: Determine whether the text subsequence contains a predetermined key subsequence;

[0024] If included, the emphasized subsequence is displayed in a predetermined format while playing the voice subsequence;

[0025] If not, the text subsequence is played directly, and the next pause point in the speech sequence is obtained, and the next pause point is used as the current pause point, and the process returns to step S202.

[0026] The step S200 further includes:

[0027] The second number of emphasis subsequence identification processes is used to identify whether an emphasis subsequence exists in the speech sequence.

[0028] As a more specific method scheme, the second aspect of the present invention provides a method for identifying and displaying a key subsequence of a speech sequence, comprising the following steps:

[0029] S510: Acquire the current speech sequence;

[0030] S520: Identify a first number of pause points included in the current speech sequence, and activate a second number of key subsequence identification processes;

[0031] S530: Divide the current speech sequence into a third number of speech subsequences based on the first number of pause points.

[0032] S540: using the second number of key subsequence identification processes to identify in parallel whether each of the speech subsequences contains a predetermined key subsequence;

[0033] S550: If two adjacent speech subsequences contain the same predetermined key subsequence, the two adjacent speech subsequences are merged into one speech subsequence;

[0034] S560: Playing the voice subsequences in sequence, and if the currently played voice subsequence includes a predetermined key subsequence, displaying the predetermined key subsequence in a predetermined format at the same time;

[0035] The focus subsequence includes a reaction relationship of at least one chemical substance and / or chemical substance combination.

[0036] Compared with the method described in the first aspect, the further improvement of the method described in the second aspect lies in steps S540-S560, especially step S550 "If two adjacent speech subsequences contain the same predetermined key subsequence, then the two adjacent speech subsequences are merged into one speech subsequence". In actual operation, due to this improvement, the processing efficiency of the key subsequence can be further improved while saving the number of processes.

[0037] Specifically, the second number is greater than the third number;

[0038] Displaying the focused subsequence in a predetermined format includes: displaying at least one chemical formula corresponding to the at least one chemical substance and / or a chemical reaction formula corresponding to the combination of chemical substances in the form of a picture.

[0048] More specifically, the speech recognition end includes a pause point recognition unit, a subsequence segmentation unit, a subsequence recognition unit, and a subsequence merging unit;

[0049] The pause point recognition unit is used to recognize the pause points contained in the speech sequence;

[0050] The subsequence segmentation unit is used to segment the speech sequence into a plurality of speech subsequences based on the pause points;

[0051] The subsequence identification unit is used to identify whether each of the speech subsequences contains a predetermined key subsequence;

It can highlight the key subsequences in these voice sequences, allowing both parties in the voice interaction to quickly and accurately absorb the key content, thereby improving the efficiency of voice communication.

In actual operation, due to this improvement, the processing efficiency of the key subsequence can be further improved while saving the number of processes.

[0106] Figure 4 is realized Figure 1 or Figure 3 Schematic diagram of unit modules of a system for identifying and displaying a key subsequence of a speech sequence in the method for identifying and displaying a key subsequence of a speech sequence.

[0107] exist Figure 4 , a system for identifying and displaying a key subsequence of a speech sequence is shown, including a speech receiving end, a speech recognition end, and a speech display end.

[0108] The voice receiving end in this embodiment is used to receive a voice sequence;

[0109] The speech recognition end is used to identify pause points included in the speech sequence and whether the speech sequence includes a key subsequence;

[0110] The voice display terminal is used to display the key subsequence on a display interface in a predetermined format;

[0111] The speech recognition end uses pause points contained in the speech sequence as nodes to identify whether the speech sequence contains a key subsequence;

[0112] The focus subsequence includes a reaction relationship of at least one chemical substance and / or chemical substance combination;

[0113] Displaying the key subsequence on the display interface in a predetermined format includes: displaying at least one chemical formula corresponding to the at least one chemical substance and / or a chemical reaction formula corresponding to a combination of chemical substances as a picture.

[0114] Specifically, displaying the key subsequence on the display interface in a predetermined format includes: displaying at least one chemical formula corresponding to a chemical substance and / or a chemical reaction formula, a chemical molecular formula, an electronic structure formula of a chemical substance, etc. corresponding to a chemical substance combination as a picture.

[0115] exist Figure 4 Based on this, see further Figure 5 The system also includes a voice broadcast terminal;

[0116] The voice announcement terminal is used to announce the key subsequence while displaying the key subsequence on a display interface in a predetermined format at the voice display terminal.

[0117] Figure 6 It shows Figure 4 A schematic diagram of the internal structure of the speech recognition terminal in the system for identifying and displaying key subsequences of a speech sequence.

[0118] The speech recognition terminal includes a pause point recognition unit, a subsequence segmentation unit, a subsequence recognition unit, and a subsequence merging unit;

[0119] The pause point recognition unit is used to recognize the pause points contained in the speech sequence;

[0120] The subsequence segmentation unit is used to segment the speech sequence into a plurality of speech subsequences based on the pause points;

[0121] The subsequence identification unit is used to identify whether each of the speech subsequences contains a predetermined key subsequence;

[0122] The subsequence merging unit is used for merging two adjacent speech subsequences into one speech subsequence if the two adjacent speech subsequences contain the same predetermined key subsequence.

[0123] Figure 7 It is a schematic diagram of the display effect after the technical solution of the present invention is implemented.

[0124] Figure 7 The current speech sequence obtained in is:

[0125] "There are two situations in the reaction between sodium hydroxide and carbon dioxide: first, a small amount of carbon dioxide reacts with sodium hydroxide to produce sodium carbonate and water; second, an excess of carbon dioxide reacts with sodium hydroxide to produce sodium bicarbonate."

[0126] Among them, multiple speech pause points can be identified, which are specifically manifested as corresponding punctuation mark positions, such as "colon:, semicolon; period.", etc. The identification and extraction of speech pause points belong to the existing technology and will not be expanded in this embodiment.

[0127] For the speech subsequence before the first speech pause point (there are two situations for the reaction of sodium hydroxide and carbon dioxide), identify the subsequence containing the predetermined key point, namely, "chemical substance and / or chemical substance combination" (sodium hydroxide and carbon dioxide);

[0128] Therefore, while playing the voice sequence, the key subsequence (sodium hydroxide and carbon dioxide) is displayed in a predetermined format, such as Figure 7 The electronic (molecular) structural formula of sodium hydroxide and carbon dioxide described in .

[0129] Similarly, the predetermined key subsequence is continuously identified, i.e., “chemical substances and / or chemical combinations” (a small amount of carbon dioxide reacts with sodium hydroxide to generate sodium carbonate and water) and the key subsequence (a small amount of carbon dioxide reacts with sodium hydroxide to generate sodium carbonate and water) is displayed in a predetermined format while the voice sequence is played, such as Figure 7 The first reaction combination formula of sodium hydroxide and carbon dioxide is (2NaOH+CO2=Na2CO3+H2O).

[0130] Similarly, the predetermined key subsequence is continuously identified, i.e., "chemical substance and / or chemical substance combination" (excess carbon dioxide and sodium hydroxide react to generate sodium bicarbonate) and the key subsequence (excess carbon dioxide and sodium hydroxide react to generate sodium bicarbonate) is displayed in a predetermined format while the voice sequence is played, such as Figure 7 The second reaction combination formula of sodium hydroxide and carbon dioxide (NaOH+CO2=NaHCO3) is shown in FIG.

[0131] It can be seen that the technical solution of the present invention is essentially to generate a summary image containing the key subsequence and then display it when the key subsequence is identified in the original speech sequence.

[0132] Therefore, the technical solution of the present invention can also be implemented as follows:

[0133] S2011: identifying a current pause point in the acquired speech sequence;

[0134] S2021: Translate the speech subsequence before the current pause point into a text subsequence;

[0135] S2031: Determine whether the text subsequence contains a predetermined key subsequence;

[0136] If included, a picture summary corresponding to the voice subsequence is generated based on the predetermined key subsequence, and the picture summary corresponding to the voice subsequence is displayed in a predetermined format while the voice subsequence is played.

[0137] If not, the text subsequence is played directly, and the next pause point in the voice sequence is obtained, and the next pause point is used as the current pause point, and the process returns to step S2021.

[0138] It can be seen that the present invention is aimed at the problem that in certain special occasions, especially occasions containing specific vocabulary and specific format vocabulary, such as voice communication in the chemical field, molecular field, etc., the voice sequence usually contains a large number of professional chemical vocabulary. It can highlight the key subsequences in these voice sequences, so that both parties in the voice interaction can quickly and accurately absorb the key content, thereby improving the efficiency of voice communication.

[0139] The present invention can also recognize audio streams as text in real time, which is suitable for long sentence voice input, audio and video subtitles, conferences, speech subtitles on the same screen, etc., intelligent language processing, and can also perform intelligent error correction on intermediate recognition results, display intermediate text results in real time, quickly identify key audio streams, and quickly display the recognition results in the form of picture text summaries. For example, at least one chemical formula corresponding to a chemical substance and / or a chemical reaction formula, chemical molecular formula, electronic structure formula of a chemical substance corresponding to a combination of chemical substances, etc. are displayed as pictures.

[0140] It should be pointed out that Figure 1-Figure 3 The steps or methods and processes can all be automatically implemented by computer program instructions. Figure 8 , provides a terminal device, which can be a data interaction device, including a bus, a processor and a memory, the memory is used to store a computer program, the computer program includes program instructions, and the processor is used to execute the program instructions stored in the computer storage medium.
