Description

Technical Field

[0001] The present invention relates to the field of audio processing technology, and in particular to an audio playback method, device and equipment. Background Art

[0002] Speech synthesis can convert any text message into standard, fluent speech in real time, effectively giving a machine an artificial mouth. It involves multiple disciplines, including acoustics, linguistics, digital signal processing, and computer science. It is a cutting-edge technology in Chinese information processing, primarily addressing the problem of converting text into audible sound—in other words, enabling machines to speak like humans.

[0003] The commonly held concept of "making machines speak like humans" is fundamentally different from traditional audio playback devices (systems). Traditional audio playback devices (systems), such as tape recorders, achieve this by pre-recording and then playing back audio. This approach has significant limitations in terms of content, storage, transmission, convenience, and timeliness. Computer-aided speech synthesis, on the other hand, can convert any text into highly natural speech at any time, truly enabling machines to "speak like humans."

[0004] Current speech synthesis methods, such as the implementation process of TTS (Text To Speech), have at least the following problems: when the network is unstable, playback may be stuck. Summary of the Invention

[0005] In view of the above problems, embodiments of the present invention are proposed to provide an audio playback method, apparatus, and device that overcome the above problems or at least partially solve the above problems.

[0006] According to one aspect of an embodiment of the present invention, there is provided an audio playback method, which is applied to a client, and the method includes:

[0007] Send an audio pre-synthesis request to the server;

[0008] receiving at least one audio file of pre-synthesized audio sent by the server according to the audio pre-synthesis request;

[0009] According to the playback delay parameter, the at least one correct audio file that has been cached is played one by one in sequence within the corresponding timing duration until the timing duration ends. The timing duration corresponding to the playback delay parameter is determined based on the estimated playback duration of the pre-synthesized audio.

[0010] According to another aspect of an embodiment of the present invention, there is provided an audio playback device, applied to a client, the device comprising:

[0011] a transceiver module configured to send an audio presynthesis request to a server; and receive at least one audio file of presynthesized audio sent by the server according to the audio presynthesis request;

[0012] The processing module is configured to play the at least one correctly cached audio file in sequence one by one within a corresponding timing duration according to a playback delay parameter until the timing duration expires, where the timing duration corresponding to the playback delay parameter is determined based on an estimated playback duration of the pre-synthesized audio.

[0013] According to another aspect of an embodiment of the present invention, there is provided a computing device, comprising: a processor, a memory, a communication interface, and a communication bus, wherein the processor, the memory, and the communication interface communicate with each other via the communication bus;

[0014] The memory is used to store at least one executable instruction, and the executable instruction enables the processor to execute operations corresponding to the above-mentioned audio playing method.

[0015] According to another aspect of the embodiments of the present invention, a computer storage medium is provided, wherein the storage medium stores at least one executable instruction, and the executable instruction enables a processor to perform operations corresponding to the above-mentioned audio playback method.

[0016] According to the solution provided by the above-mentioned embodiment of the present invention, the audio playback method is applied to the client, by sending an audio pre-synthesis request to the server; receiving at least one audio file of pre-synthesized audio sent by the server according to the audio pre-synthesis request; according to the playback delay parameter, within the corresponding timing duration, the correct at least one audio file that has been cached is played one by one in sequence until the timing duration ends. The timing duration corresponding to the playback delay parameter is determined according to the estimated playback duration of the pre-synthesized audio. In this way, an audio file with a jamming abnormality can be played within the timing duration corresponding to the playback delay parameter. The cached audio file with the jamming abnormality can be played, thereby improving the smoothness of the audio playback on the client, thereby solving the jamming problem of speech synthesis under network abnormalities and improving the smoothness of audio playback on the client.

[0023] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0024] The following embodiments of the present invention address the problem in the prior art of speech synthesis methods that the smoothness of audio playback cannot be guaranteed when a network anomaly occurs. An audio playback method is proposed. When an audio file is played abnormally, the cached audio file is played according to a playback delay parameter within a timed duration corresponding to the playback delay parameter, thereby ensuring smooth audio playback without any lag.

[0025] Figure 1 FIG. 1 is a flow chart of an audio playback method provided by an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0026] Step 11, sending an audio pre-synthesis request to the server;

[0027] Step 12: Receive at least one audio file of pre-synthesized audio sent by the server according to the audio pre-synthesis request; here, the pre-synthesized audio is audio data requested by an audio pre-synthesis request. For example, if the audio data requested by the audio pre-synthesis request is a paragraph of an e-book, if the audio data requested by the audio pre-synthesis request is a paragraph, the audio file is a sentence in the paragraph;

[0028] Step 13: Play the at least one correct audio file that has been cached one by one in sequence within a corresponding timing duration according to the playback delay parameter until the timing duration ends. The timing duration corresponding to the playback delay parameter is determined based on the estimated playback duration of the pre-synthesized audio.

[0029] This embodiment sends an audio pre-synthesis request to a server; receives at least one audio file of pre-synthesized audio sent by the server according to the audio pre-synthesis request; and plays the at least one correct audio file that has been cached one by one in sequence within a corresponding timing duration according to a playback delay parameter until the timing duration ends, thereby improving the smoothness of client audio playback.

[0030] In an optional embodiment of the present invention, after step 12, the audio playback method may further include:

[0031] Step 121: Store the at least one audio file in a cache in the order in which it is received.

[0032] In a specific implementation example, the client sends an audio pre-synthesis request carrying text to the server for the first time. For example, the current synthesis capability standard is a maximum of 500 characters per request.

[0033] After receiving the first synthesis request from the client, the server synthesizes the text into multiple audio files based on the sentences / paragraphs in the text, and sends the multiple audio files to the client in sequence.

[0034] The client receives multiple synthesized audio files in sequence and stores them in the local client cache in sequence.

[0035] The client calculates the duration (in milliseconds) required to play all the audio files in an audio presynthesis request based on the received cache data of the multiple audio files and the playback speed of the player set by the client.

[0036] In an optional embodiment of the present invention, step 13 may include:

[0037] Step 131, obtaining the playback delay parameter according to the estimated playback duration of the pre-synthesized audio;

[0038] In a specific implementation, the start time of playing the pre-synthesized audio is determined based on the reception time of the first audio file in the cache, and the total playing time of the at least one audio file is estimated based on the playing speed of the player to obtain the end time of playing the pre-synthesized audio.

[0039] Obtaining an estimated playback duration of the pre-synthesized audio according to the start playback time and the end playback time of the pre-synthesized audio, and using the estimated playback duration of the pre-synthesized audio as the duration corresponding to the playback delay parameter;

[0040] Step 132: Play the at least one buffered audio file one by one in sequence within a timing duration corresponding to the playback delay parameter.

[0041] In a specific implementation, the method waits for the timing duration corresponding to the playback delay parameter, and continues to play the at least one correct audio file that has been cached until the duration corresponding to the playback delay parameter ends.

[0042] In this embodiment, when the client locates the first received audio file, it begins playing the audio file. Simultaneously, a delay parameter timer is started, whose timing duration corresponds to the playback delay parameter. When a playback anomaly occurs, the message asynchronous processing mechanism is initiated. Here, the timing duration of the delay parameter timer is equal to the total playback duration of all audio files in a single audio presynthesis request at the current playback rate. At the same time, field information such as the sequence number, playback start time, playback end time, and playback duration of each presynthesized audio segment is provided externally.

[0043] When a network anomaly causes a playback anomaly, it may cause multiple pre-synthesized audios received based on multiple pre-synthesis requests to exist in the client cache. At this time, the client starts the message asynchronous processing mechanism to process the pre-synthesized audio in the cache, which mainly includes: when a network anomaly prompt is received or an error code is generated, the exception information / error code is not processed, and the information is only cached in the cache, which is preferably a memory cache. At the same time, the current pre-synthesized audio continues to be played until the delay parameter timer expires, and the error code, network anomaly information and information related to the progress of this playback are reported. The client selects a correct pre-synthesized audio in the cache for playback based on the text, audio sequence number, audio duration and other information of the pre-synthesized audio that has been played and the delay parameter related data. At the same time, all other pre-synthesized audios in the cache are released.

[0044] The above-mentioned network anomaly judgment can use the existing SDK (software toolkit) anomaly detection distribution mechanism detection, network anomaly prompts, error code generation and other aspects to discover network anomalies.

[0045] Each pre-synthesized audio must be played until the delay parameter timer expires. When a network exception occurs, the client starts the message asynchronous processing mechanism and only caches the exception / error information. Each pre-synthesized audio needs to remain in the playing state before the delay parameter timer expires.

[0046] In an optional embodiment of the present invention, when the duration corresponding to the playback delay parameter ends, the method may further include:

[0047] Step 14, obtaining the playback progress, playback exception information and error code of the pre-synthesized audio;

[0048] Step 15: Report the playing progress, playing exception information and error code of the pre-synthesized audio to the server.

[0049] In this embodiment, after each pre-synthesized audio is played and the delay parameter timer expires, an error code and data related to the current playback progress are reported. Simultaneously, based on the text, audio sequence number, audio duration, and other information of the pre-synthesized audio that has been played, as well as the playback start time, playback end time, and playback duration data, the client selects a correct pre-synthesized audio from the memory buffer for playback. After the pre-synthesized audio begins playing, the client deletes all remaining pre-synthesized audio in the memory and, based on the text content of the currently playing pre-synthesized audio, initiates the next pre-synthesis request again until no network anomalies are reported. After the current pre-synthesized audio is played, the client closes the message asynchronous processing mechanism and resumes the normal synthesis process.

[0050] In an optional embodiment of the present invention, the audio playback method may further include:

[0051] Step 16: Release the cached erroneous audio file so that the memory can continue to cache the audio file of the next audio pre-synthesis request.

[0052] In an optional embodiment of the present invention, in the audio playing method, after releasing the cached erroneous audio file, the method may further include:

[0053] Step 17: determining a starting position of a next audio presynthesis request according to the playback progress of the presynthesized audio;

[0054] Step 18: Initiate a next audio pre-synthesis request to the server according to the starting position of the next audio pre-synthesis request;

[0055] Step 19: Receive at least one audio file of the next pre-synthesized audio sent by the server according to the next audio pre-synthesis request.

[0056] In this embodiment, the client determines the starting position of the next pre-synthesis request based on the text content corresponding to the currently played pre-synthesized audio, and initiates the next audio pre-synthesis request until there are no network anomalies and the message asynchronous processing mechanism is closed.

[0057] The following combination Figure 2 The specific implementation process of the method shown in the process description is as follows:

[0058] The server sends the pre-synthesized audio according to the client's pre-synthesis request;

[0059] When the client starts playing the first audio file received, it immediately sends an audio synthesis request to the server again to pre-synthesize the next pre-synthesized audio. After the server completes the synthesis, it sends the multiple audio files synthesized in this request to the client in sequence. After receiving them, the client caches them in the client memory in sequence.

[0060] Under normal circumstances, after the client receives the first audio file, it is played and the timer is started. When the duration corresponding to the delay parameter is counted out, the entire pre-synthesized audio is played and the next pre-synthesized audio is played.

[0061] When an exception occurs, the client must wait until the delay parameter of this exception is timed out (continue playing the buffered audio file) before reporting the error code and playback progress information.

[0062] When reporting the error code, the client selects the correct next pre-synthesized audio segment from the cached data for playback based on the request text, audio sequence number, playback progress information, and delay parameters.

[0063] All erroneous buffers are released according to the correct delay parameter of the next audio segment, and the next audio segment pre-synthesis operation is carried out according to the text-to-speech TTS synthesis mechanism.

[0064] The above-described embodiments of the present invention address the issue of audio playback lag during speech synthesis playback under network anomalies, thereby improving the smoothness of audio playback on the client side. The solutions described in these embodiments can significantly enhance user experience, particularly in scenarios where speech synthesis capabilities are used for extended periods, such as reading, listening to books, or consuming news.
