It should be understood that the content described in this section is not intended to identify a key or important feature of the embodiments of the present application, nor is it intended to limit a scope of the present application. Other features of the present application will be easily understood through the following description.
The drawings are used to better understand the solutions, and do not constitute a limitation to the application, where:
The following describes exemplary embodiments of the present application with reference to the drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be regarded as merely exemplary. Therefore, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from a scope of the present application. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.
At present, most of the vehicle-and-machine systems of vehicles are Android systems, and the use of a microphone is limited in the Android system. When an application program interface (API) of the system is called to record microphone data, if a process is already using the microphone, the Android system will return an error code when other processes request to use the microphone. This error code indicates that other processes are using the microphone, and it takes time to activate and release the microphone.
A wake-up engine and a recognition engine in a voice interactive application of the vehicle both rely on the microphone to work, and the wake-up engine and the recognition engine respectively correspond to a process and need to actively acquire audio data collected by the microphone. Generally, the vehicle-and-machine system may maintain a thread pool. When the wake-up engine needs to be started, the corresponding process of the wake-up engine uses the thread pool to create a new thread, and at the same time initializes the AudioRecord (the starting-recording related class in the Android system) object (that is, initialize the microphone), actives the microphone, collects and inputs audio data to the wake-up engine. After detecting that the wake-up is successful, the wake-up engine exits the current thread and releases the AudioRecord object, thereby releasing the microphone. Then the corresponding process of the recognition engine uses the thread pool to create a new thread, reinitializes the AudioRecord object in this thread, actives the microphone, and collects and sends audio data to the recognition engine. After returning the recognition result, the recognition engine exits the current thread, releases the AudioRecord object, and thus releases the microphone. Then when there is needs to wake up or recognition, the thread is restarted, the microphone is initialized, audio data is collected, and the microphone is released, and so on. Since it takes time to activate and release the microphone, the microphone may not be ready when the wake-up engine and the recognition engine need to work, therefore, in the audio data acquired by the wake-up engine and the recognition engine, some of voice from a user will be lost. Maintenance of the thread pool and multiple times of creation and consumption of the microphone object result in a waste of CPU and memory.
The present application provides a voice data processing method and apparatus, a device, and a storage medium, which are applied to artificial intelligence fields such as intelligent transportation and voice technologies to improve efficiency and accuracy of a voice interactive application.
The voice data processing method provided in the present application is specifically applied to the voice interactive application, and can be devices, such as vehicle-and-machine systems and smart audios based on Android system voice interactive applications. A voice interactive application usually includes two modules, e.g., a wake-up engine and a voice recognition engine. In the embodiment of the present application, as shown in
step S201: starting a microphone management thread to collect audio data acquired by a microphone in a process of a voice interactive application.
In the embodiment, in the same process of the voice interactive application, two modules, e.g., the wake-up engine and the voice recognition engine, are implemented. The wake-up engine and the voice recognition engine respectively correspond to a thread. The wake-up function is realized by using the wake-up thread, and the voice recognition function is realized by using the voice recognition thread. The microphone management thread is responsible for requesting the microphone and collecting the audio data acquired by the microphone. The wake-up engine and the voice recognition engine do not need to separately request the microphone to collect the audio data acquired by the microphone.
Step S202: when the voice interactive application is in a non-wake-up state, starting the wake-up thread to perform wake-up processing on the voice interactive application according to the audio data.
After the microphone management thread collects the audio data acquired by the microphone, according to a current state of the voice interactive application, when the voice interactive application is in a non-wake-up state, then a wake-up thread corresponding to the wake-up engine is started, and wake-up processing is performed on the voice interactive application according to the audio data.
After the voice interactive application is successfully waked up, the voice interactive application enters a non-wake-up state. When the audio data acquired by the microphone is subsequently collected, the voice recognition thread can directly perform voice recognition on the audio data.
In the embodiment of the application, in the process of the voice interactive application, the microphone management thread is specifically responsible for collecting audio data acquired by the microphone, and then based on the state of the voice interactive application, when the voice interactive application is in a non-wake-up state, the wake-up thread is started to perform wake-up processing on voice interactive applications based on the audio data. The wake-up engine does not need to request the microphone separately. Furthermore, after the wake-up is performed successful and entering the non-wake-up state, there is no need for the recognition engine to request the microphone separately, which can directly perform voice recognition on the audio data collected by the microphone management thread, thus the wake-up engine and the recognition engine can be realized in the same process. There is no need for the wake-up engine and the recognition engine to request the use of the microphone in turn, thereby improving the efficiency of collecting audio data acquired by the microphone by the wake-up engine and the recognition engine, avoiding the problem of losing part of the acquired audio data due to waiting for preparation of the microphone device, thus improving the efficiency and accuracy of the voice interactive application.
As shown in
step S301: starting a microphone management thread in a process of a voice interactive application in response to a starting instruction for the voice interactive application.
In the embodiment, when the voice interactive application is started, the microphone management thread is started in the process of the voice interactive application. The microphone management thread is a thread dedicated to requesting a microphone, collecting audio data acquired by the microphone, and releasing the microphone.
Illustratively, when the user starts the voice interactive application, a starting instruction is sent to the voice data processing apparatus. For example, usually when the user starts the vehicle, the vehicle-and-machine system is powered on, or the user plugs in a smart audio device, the voice interactive application on the vehicle-and-machine system or smart audio will be started. At this time, it can be considered that the starting instruction for the voice interactive application is received. The microphone management thread is started in the process of the voice interactive application.
In response to the starting instruction for the voice interactive application, the voice data processing apparatus starts the microphone management thread in the process of the voice interactive application.
Step S302: through the microphone management thread, calling an application programming interface (API) corresponding to the microphone, initializing the microphone and collecting the audio data acquired by the microphone.
After the microphone management thread is started in the process, through the microphone management thread, the application programming interface (API) corresponding to the microphone is called to request the use of microphone, and the microphone is initialized. After the requesting of the microphone is completed, the audio data acquired by the microphone is collected.
In the embodiment, a specific implementation method of requesting a microphone and collecting audio data acquired by the microphone through the microphone management thread is similar to the method of requesting a microphone and collecting audio data acquired by the microphone in the prior art through a process or on-site, which is not repeated here in the embodiments.
In addition, in the embodiment, after requesting the microphone, the microphone management thread continues to use the microphone and collects the audio data acquired by the microphone, and releases the microphone until receiving a closing instruction for the voice interactive application.
For example, when the vehicle-and-machine system is powered off, or when the user powers off the smart audio device, the voice interactive application on the vehicle-and-machine system or smart audio will be closed. At this time, it can be considered that the closing instruction for the voice interactive application is received, and the microphone management thread releases the microphone.
Through the above steps S301-S302, the microphone management thread is started, and the audio data acquired by the microphone is collected. When the voice interactive application is started, the microphone management thread can be started in the process of the voice interactive application to request the microphone, and the microphone management thread continues to use the microphone and collects the audio data acquired by the microphone until the voice interactive application is closed, at which time the microphone management thread releases the microphone. Hence, the requesting of the microphone is performed for one time, but the use of the microphone lasts for a long time, thereby reducing the waste of CPU and memory due to the maintenance of the thread pool and multiple times of requesting and releasing of the microphone.
In the embodiment, the voice management thread in the same process may be responsible for distributing the audio data (which is acquired by the microphone and collected through the microphone management thread) to the thread corresponding to the wake-up engine and voice recognition engine that need the audio data acquired by the microphone.
After starting the microphone management thread to collect the audio data acquired by the microphone, the microphone management thread may transmit the audio data to the voice management thread according to the following steps S303-S305.
Step S303: determining whether there exists a consumer of the audio data through the microphone management thread.
Where the consumer of the audio data refers to the thread requesting the use of the audio data, that is, the thread corresponding to a functional module (including the wake-up engine and the voice recognition engine) that needs to use the audio data.
When it is determined that there exists a consumer of the audio data, execute step S304.
When it is determined that there exists no consumer of the audio data, execute step S305.
Illustratively, when the audio data acquired by the microphone is needed, the functional module can register, and the microphone management thread can determine whether there exists a consumer of the audio data based on the registration information every time the microphone management thread collects a frame of audio data d.
Optionally, when the wake-up engine or the voice recognition engine needs to use the audio data acquired by the microphone, a callback function can be registered with the microphone management thread or the voice data processing device, and the microphone management thread can query the registered callback function. Each time the microphone management thread collects a frame of audio data, it determines whether there exists the registered callback function by querying the registered information. If there exists the registered callback function, it is determined that there exists a consumer of the audio data. If there exists no registered callback function, it is determined that there exists no consumer of the audio data. Optionally, the voice management thread can transmit the audio data to the corresponding functional module by calling the registered callback function.
Step S304: sending the audio data to the voice management thread when it is determined that there exists a consumer of the audio data.
If in the above step S303, it is determined that there exists a consumer of the audio data through the microphone management thread, then in this step, the microphone management thread sends the audio data to the voice management thread, and the voice management thread subsequently distributes the audio data to the customer who needs to use the audio data.
Step S305: when it is determined that there exists no consumer of the audio data, discarding the audio data and acquiring a next frame of audio data.
In the above step S303, when it is determined that there exists no consumer of the audio data through the microphone management thread, then in this step, the microphone management thread discards the audio data and continues to collect the next frame of audio data.
Step S306: determining a current state of the voice interactive application through the voice management thread.
Optionally, the state flag information of the voice interactive application can be stored through a state flag bit.
In this step, the state flag information of the voice interactive application is acquired through the voice management thread, and a current state of the voice interactive application is determined according to the state flag information.
In addition, the state flag information of the voice interactive application can also be implemented by any method for storing state information in the prior art, which will not be repeated here in the embodiment.
After determining the current state of the voice interactive application, the voice management thread distributes the audio data to the wake-up engine and/or recognition engine that needs to use the audio data according to the current state of the voice interactive application according to the following steps S307-S310.
Step S307: when the voice interactive application is in a non-wake-up state, sending the audio data to the wake-up thread through the voice management thread.
When the voice interactive application is in the non-wake-up state, the voice interactive application needs to be waked up first, and then the audio data is sent to the wake-up thread through the voice management thread.
Step S308: performing wake-up processing on the voice interactive application according to the audio data through the wake-up thread.
After acquiring the audio data, the wake-up thread performs wake-up processing on the voice interactive application according to the audio data.
After the voice interactive application is waked up successfully, the state flag information is set to the wake-up state, and the voice interactive application enters the wake-up state.
Step S309: when the voice interactive application is in a wake-up state, sending the audio data to the voice recognition thread through the voice management thread.
When the voice interactive application is in the wake-up state and the recognition engine needs to recognize user instruction information in the audio data, then the audio data is sent to the voice recognition thread through the voice management thread.
Step S310: performing voice recognition on the audio data through the voice recognition thread.
After acquiring the audio data, the voice recognition thread performs voice recognition on the audio data to identify the user instruction information in the audio data.
However, in an application scenario, after the user sends an interactive command, during the process of voice recognition by the recognition engine or when playing response information for the interactive command, the user wants to interrupt this interaction and enter directly to the next interaction, the voice interactive application needs to be waked up again at this time. However, in the current voice interactive application, after the wake-up is successful and the recognition engine is started, the recognition engine will occupy the microphone, and the wake-up engine will not work, therefore, the needs of interrupting or canceling the current recognition by virtue of a wake-up expression during the recognition process, directly waking up and entering to the next interaction cannot be met.
In an optional implementation, when the voice interactive application is in a non-wake-up state, the audio data is sent to the wake-up thread and the voice recognition thread through the voice management thread; the wake-up processing is performed on the voice interactive application according to the audio data through the wake-up thread and the voice recognition is performed on the audio data through the voice recognition thread. In this way, if the user wants to interrupt the current interaction process and directly enter the next interaction by waking up again, then the user may speak out the wake-up expression, and the audio data acquired by the microphone contains the wake-up expression from the user. After acquiring the audio data, in the wake-up state, the voice management thread can also send the audio data to the wake-up thread corresponding to the wake-up engine, so as to perform wake-up processing on the voice interactive application again through the wake-up thread to meet the user's needs in the above-mentioned scenario.
Exemplarily, in this implementation manner, a microphone management class can be encapsulated for starting the microphone management thread, through the microphone management thread, the microphone is initialized, the audio data acquired by the microphone is collected, and the audio data is sent through a provided interface to the voice management class; a voice management class can be encapsulated for coordinating the recognition engine and the wake-up engine, a voice management thread is started, the audio data is acquired from the microphone management thread, and the audio data is distributed to the functional modules (including the wake-up engine and/or the recognition engine) that need the audio data to realize the management of collecting of the audio data acquired by the microphone. As shown in
In the embodiment of the application, in the same process of the voice interactive application, the microphone management thread is specifically responsible for collecting the audio data acquired by the microphone and transmitting the audio data to the voice management thread, and then the voice management thread is responsible for distributing the audio data to functional modules (including the wake-up engine and/or the recognition engine) that need the audio data according to the state of the voice interactive application, in this way, the wake-up engine and recognition engine can be realized in the same process without requesting the microphone by the wake-up engine and the recognition engine separately, thereby improving the efficiency of collecting the audio data acquired by the microphone by the wake-up engine and the recognition engine, avoiding the problem of losing part of the audio data due to waiting for preparation of the microphone device, thus improving the efficiency and accuracy of the voice interactive application; in addition, when the voice interactive application is started, the microphone management thread is started in the process of the voice interactive application to request the microphone. The microphone management thread continues to use the microphone and collects the audio data acquired by the microphone, until the voice interactive application is closed. The microphone management thread releases the microphone, requests the microphone for one time and uses it for a long time, thus reducing the waste of CPU and memory due to the maintenance of a thread pool and multiple times of requesting and releasing of the microphone. Furthermore, when the voice interactive application is in a non-wake-up state, the audio data is sent to the wake-up thread and the voice recognition thread, thereby interrupting the current voice recognition of the recognition engine through the wake-up engine, waking up the voice interactive application again, and directly entering to the next interaction to meet the needs of a user.

The audio data processing module 502 is configured to: when the voice interactive application is in a non-wake-up state, start a wake-up thread to perform wake-up processing on the voice interactive application according to the audio data.

The wake-up engine does not need to request the microphone separately. Furthermore, after the wake-up is performed successful and entering the non-wake-up state, there is no need for the recognition engine to request the microphone separately, which can directly perform voice recognition on the audio data collected by the microphone management thread, thus the wake-up engine and the recognition engine can be realized in the same process. There is no need for the wake-up engine and the recognition engine to request the use of the microphone in turn, thereby improving the efficiency of collecting audio data acquired by the microphone by the wake-up engine and the recognition engine, avoiding the problem of losing part of the acquired audio data due to waiting for preparation of the microphone device, thus improving the efficiency and accuracy of the voice interactive application.
