Background
With the development of computer technology, voice interaction devices such as intelligent sound boxes and the like are widely applied. The voice interaction equipment can acquire audio signals sent by a user through an audio receiving module such as a microphone and the like, analyze the audio signals, determine an instruction sent by the user and execute corresponding operation. Optionally, after the audio signal sent by the user is collected, the voice interaction device may play the audio signal through a sound generation module such as a speaker, and feed back the audio signal sent by the user, thereby completing the process of interacting with the user.
For a voice interaction device interacting with a user through an audio signal, a time interval from a time when a user utterance is ended to a time when the voice interaction device starts playing a fed-back audio signal is called an interaction waiting time. In the interaction waiting time, the user needs to wait for the response of the voice interaction device. Obviously, the longer the interaction latency, the worse the user experience. In order to optimize the voice interaction device, the interaction latency of the voice device needs to be determined. However, the conventional method for determining the interaction latency has a problem of being inaccurate.

The voice interaction device may interact with the user through audio data. Specifically, an instruction may be issued by voice at the user, and the instruction is referred to as a voice instruction. The voice interaction device can collect an audio signal corresponding to the voice instruction, and determine a task which the user requires to be executed by the voice interaction device according to the audio signal, so as to perform corresponding operation. In some possible implementations, to let the user know that the voice interaction device has received the instruction, the voice interaction device may play the feedback audio after receiving the voice instruction.
For example. Assuming that the user speaks the voice of "put a song of singer a for me", the voice interaction device may collect an audio signal through the microphone, and analyze the audio signal to determine that the user wants to control the voice interaction device to play the song of singer a. Then, the voice interaction device plays preset feedback audio, for example, plays "your instruction has been received" through the speaker, and indicates to the user that the user has received the instruction issued by the user. The voice interaction device may then look up the singer A's song from the network and play it.
In this process, the time interval from the end of the user utterance to the first start of the voice interaction device uttering is referred to as the interaction latency. That is, in the example mentioned above, the time interval from the time when the user finishes saying "put me for singer a", to the time when the voice interaction device starts playing "your instruction has been received" is the interaction waiting time. And in the interaction waiting time, the voice interaction equipment does not perform voice interaction with the user, and the user is in a waiting state. Obviously, the longer the interaction latency, the longer the user is in the wait state, and the worse the user experience.
Therefore, the technician can determine the interaction waiting time of the voice interaction device and then optimize the voice interaction device according to the interaction waiting time. Currently, most of the voice interaction devices are manually subjected to interaction waiting time by testers. For example, a tester may send an instruction to the voice interaction device, start timing after the instruction is sent, and stop timing after the voice fed back by the voice interaction device is heard, where the recorded time is the interaction waiting time of the voice interaction device.
Therefore, the traditional method for testing the interactive waiting time has the problems of inaccuracy and more labor consumption due to the fact that the manual timing of technicians is relied on.
In order to solve the problems in the prior art, embodiments of the present application provide a time determination method, an apparatus, a device, and a storage medium, which are described in detail below with reference to the accompanying drawings.
In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, first, a description is made with reference to a scene example shown in fig. 1.
Referring to fig. 1, the figure is a schematic diagram of a framework of an exemplary application scenario provided in an embodiment of the present application. In fig. 1, an audio source 10, a voice interaction device 20, an audio acquisition apparatus 30 and a processing apparatus 40 are included. Wherein, the sound source 10 can play voice and send out a first audio signal; the voice interaction device 20 may collect an audio signal emitted from the sound source 10, and in response to the audio signal, emit a second audio signal; the audio acquisition module 30 is located between the sound source 10 and the voice interaction device 20, and can acquire a first audio signal sent by the sound source 10 and a second audio signal sent by the voice interaction device 30; the processing module 40 is connected to the audio capture module 30, and is capable of receiving the first audio signal and the second audio signal captured by the audio capture module 30 and determining an interaction waiting time of the voice interaction device according to the first audio signal and the second audio signal. The time determination method provided by the embodiment of the present application may be executed by the processing module 40.
Alternatively, the sound source 10 may be a man-made mouth or a speaker box with a speaker, the tested voice interaction device 20 may be a smart speaker box, a smart desk lamp or other terminal devices with voice interaction functions (e.g. devices such as a mobile phone, a tablet computer, etc.), and the audio acquisition module 30 may include a microphone array, which may include one or more microphones.
It should be noted that, in the embodiment shown in fig. 1, the audio acquisition module 30 and the processing module 40 may be different devices, or may be different entity modules in the same device. For example, the audio acquisition module 30 may be a microphone or microphone array of a test device and the processing module 40 may be a processor of the same test device.
In the time determination method provided by the embodiment of the application, the voice source simulation user can send an instruction to the voice interaction device to simulate an actual voice interaction scene. The interaction waiting time of the voice interaction equipment can be determined by calculating the time interval from the time of playing the voice by the voice source to the time of playing the response voice by the voice interaction equipment.
First, the propagation process of voice and audio signals in the embodiment of the present application will be described by taking the embodiment shown in fig. 1 as an example. Referring to fig. 2, fig. 2 is an interaction diagram of voice and audio signals in a transmission process according to an embodiment of the present application, including:
s201: the sound source plays the first voice.
In the process of testing the interaction waiting time of the voice interaction device, the first voice can be played through the sound source. The first voice may be a preset segment, for example, a wakeup word of the voice interaction device, or a preset instruction of the voice interaction device.
S202: the voice interaction device and the audio acquisition module receive a first voice.
After the first voice is played by the sound source, the first voice can be collected by the audio collection module between the sound source and the voice interaction equipment, and the first voice is converted into an audio signal. Similarly, the voice interaction device may also capture the first voice and convert the first voice into an audio signal for subsequent processing.
S203: and the voice interaction equipment generates and plays the second voice according to the received first voice.
After receiving the first voice, the voice interaction device may generate a second voice for responding to the first voice according to the first voice, and play the second voice through a speaker of the voice interaction device or the like. Specifically, the voice interaction device may recognize the meaning of the first voice, determine an instruction to be completed according to the first voice, and generate and play the second voice according to the instruction. For example, assuming that the first voice is a wake-up word of the voice interaction device, the second voice may be a response word preset to answer the wake-up word.
S204: the audio acquisition module receives the second voice.
After the voice interaction device plays the second voice, the audio acquisition module may receive the second voice and convert the second voice into an audio signal.
S205: and the audio acquisition module sends the acquired audio signals to the processing module.
After converting the first speech and/or the second speech into an audio signal, the audio acquisition module may send the audio signal to the processing module. Optionally. The audio acquisition module may send the audio signal to the processing module after acquiring the audio signal corresponding to the first voice, and send the audio signal to the processing module again after acquiring the audio signal corresponding to the second voice. The audio acquisition module can also be used for storing the audio signals corresponding to the first set of voices after acquiring the audio signals and recording time information of the audio signals. After the audio signal corresponding to the second voice is collected, the audio collection module may uniformly send the audio signals corresponding to the first voice and the second voice, respectively, and the related time information to the processing module.
In some possible implementations, the audio capture module may include one or more units with capture audio functionality. For example, the audio acquisition module may include a microphone array, the microphone array may include one or more microphones, each microphone may independently receive and convert speech into audio signals, and the audio signals sent by the audio acquisition module to the processing module may include multiple segments of audio signals. Optionally, when the audio capture module comprises a plurality of units having capture audio functionality, different units having capture audio functionality may be deployed at different locations.
After receiving the audio signal acquired by the audio acquisition module, the processing module may execute the time determination method provided in the embodiment of the present application, and the specific execution process may be described as follows.
Fig. 3 is a schematic flow chart of a time determination method according to an embodiment of the present application, which is applicable to a scenario of testing an interaction waiting time of a voice interaction device. The method may be performed by any device having data processing capabilities and the device having or being in communication with audio capture capabilities.
The method is described as an example of the method being performed by a processing module of the test equipment. As shown in fig. 3, the method specifically includes the following steps:
s301: the processing module acquires an audio signal.
To determine the interaction latency of the voice interaction device, the processing module may acquire an audio signal. According to the foregoing description, the audio signal may be an audio signal collected by the audio collecting module during the interaction between the sound source and the voice interaction device, and includes a first audio signal and a second audio signal. The first audio signal is an audio signal from a sound source, and the second audio signal is an audio signal sent by the voice interaction device after receiving the first audio signal.
In this embodiment, the audio signal sent by the audio acquisition module to the further processing module may include multiple segments of audio signals, where the start time of each segment of audio signal is different. Then the processing module may determine the first audio signal and the second audio signal from the plurality of segments of audio signals captured by the audio capture module before determining the interaction latency. As can be seen from the foregoing description, the audio capturing module in the embodiment of the present application may include one unit having an audio capturing function, or may include a plurality of units having an audio capturing function. The method by which the processing module determines the first audio signal and the second audio signal in these two cases, respectively, is described below.
If the audio capture module comprises only one unit with audio capture functionality, e.g. the audio capture module comprises only one microphone, the processing module may determine the first audio signal and the second audio signal from the start time of the audio signal.
Specifically, in the process of voice interaction between the sound source and the voice interaction device, the audio acquisition module only acquires two sections of voices. The voice with the earlier starting time is the first voice played by the sound source, and the voice with the later starting time is the response of the voice interaction equipment to the first voice, namely the second voice. Then, when the audio signal sent to the processing module by the audio acquisition module includes two segments of audio signals, the processing module may determine an audio signal with an earlier start time of the two segments of audio signals as the first audio signal, and determine an audio signal with a later start time as the second audio signal.
If the audio capture module includes a plurality of units having audio capture capabilities, for example, the audio capture module includes a plurality of microphones, each unit can independently capture audio signals. In the process of voice interaction between the sound source and the voice interaction equipment, two sections of audio signals can be collected by each unit with the audio collecting function. The audio acquisition module may send more than two segments of audio signals to the processing module, and then the processing module may determine the first audio signal and the second audio signal by the following two methods. The following are described separately.
The audio acquisition module is assumed to comprise a microphone array comprising a first microphone and a second microphone for example. In the process of voice interaction between the sound source and the voice interaction equipment, the sound source plays the first voice, and the voice interaction equipment plays the second voice. In the process, the first microphone can collect the first voice and the second voice to obtain a first section of audio signal and a second section of audio signal. Similarly, the second microphone may collect the first voice and the second voice to obtain a third segment of audio signal and a fourth segment of audio signal.
In a first possible implementation, the processing module may determine the first audio signal and the second audio signal according to the positions of the first microphone and the second microphone. Specifically, assume that the distance from the first microphone to the sound source is smaller than the distance from the second microphone to the sound source, and the distance from the second microphone to the voice interaction device is larger than the distance from the first microphone to the voice interaction device. The audio device may determine the first audio signal from the first segment of audio signal and the second audio signal from the third segment of audio signal and the fourth segment of audio signal.
Because the first microphone is closer to the sound source, the first microphone has a better acquisition effect on the first voice, and then the processing module can determine the first audio signal from the first section of audio signal and the second section of audio signal acquired by the first microphone.
Optionally, the processing module may compare the intensity of the first audio signal and the intensity of the second audio signal, and if the intensity of the first audio signal is greater than the intensity of the second audio signal, it indicates that the intensity of the voice corresponding to the first audio signal is greater than the intensity of the voice corresponding to the second audio signal at the position of the first microphone. In this way, the processing module may determine that the device emitting the voice corresponding to the first segment of audio signal is a sound source, and the first segment of audio signal is an audio signal corresponding to the first voice, so as to determine the first segment of audio signal as the first audio signal.
Optionally, the processing module may compare the start times of the first section of audio signal and the second section of audio signal, and if the start time of the first section of audio signal is earlier than the intensity of the second section of audio signal, it indicates that the first microphone collects the voice corresponding to the first section of audio signal first, and then collects the voice corresponding to the second section of audio signal, where the first section of audio signal is the audio signal corresponding to the first voice. In this way, the processing module may determine the first segment of audio signals as first audio signals.
Similarly, since the second microphone is closer to the voice interaction device, the second microphone has a better acquisition effect on the second voice, and then the processing module may determine the second audio signal from the third segment of audio signal and the fourth segment of audio signal acquired by the second microphone.
Optionally, the processing module may compare the intensities of the third and fourth segments of audio signals, and if the intensity of the third segment of audio signal is greater than the intensity of the fourth segment of audio signal, it indicates that the intensity of the voice corresponding to the third segment of audio signal is greater than the intensity of the voice corresponding to the fourth segment of audio signal at the position of the second microphone. In this way, the processing module may determine that the device emitting the voice corresponding to the third section of audio signal is the voice interaction device, and the third section of audio signal is the audio signal corresponding to the second voice, so as to determine the third section of audio signal as the second audio signal.
Optionally, the processing module may compare start times of the third and fourth segments of audio signals, and if the start time of the third segment of audio signal is earlier than the intensity of the fourth segment of audio signal, it indicates that the second microphone first acquires a voice corresponding to the third segment of audio signal, and then acquires a voice corresponding to the fourth segment of audio signal, where the fourth segment of audio signal is an audio signal corresponding to the second voice. In this way, the processing module may determine the fourth segment of audio signal as the second audio signal.
In a second possible implementation, the processing module may determine the first audio signal and the second audio signal according to the respective start times and intensities of the first segment of audio signal, the second segment of audio signal, the third segment of audio signal, and the fourth segment of audio signal.
Specifically, the processing module may compare start times of two audio signals collected by the same microphone, and determine an audio signal corresponding to the first voice and an audio signal corresponding to the second voice from the two audio signals collected by the same microphone.
For example. The processing module may compare respective start times of the first and second segments of audio signals and compare respective start times of the third and fourth segments of audio signals. If the start time of the first section of audio signal is earlier than the start time of the second section of audio signal, it is indicated that the acquisition time of the first section of audio signal is earlier, the first section of audio signal is acquired by the first voice, and then it can be determined that the second section of audio signal is acquired by the second voice. Similarly, if the start time of the third section of audio signal is earlier than the start time of the fourth section of audio signal, it is indicated that the acquisition time of the third section of audio signal is earlier, the third section of audio signal is acquired from the first voice, and it can be determined that the fourth section of audio signal is acquired from the second voice.
Then, the processing module may compare the intensities of two audio signals corresponding to the same voice, and determine the audio signal with higher intensity as the first audio signal or the second audio signal.
For example, the processing module may compare the strength of the first and third segments of audio signals. Because the first section of audio signal and the third section of audio signal are obtained by collecting the first voice, the audio signal with higher intensity in the first section of audio signal and the third section of audio signal is the audio signal with better effect on collecting the first voice. Then if the intensity of the first segment of audio signal is greater than the intensity of the third segment of audio signal, which indicates that the first microphone is better for capturing the first speech than the second microphone, the processing module may determine the first segment of audio signal as the first audio signal.
Similarly, the processing module may compare the strength of the second segment of audio signal and the fourth segment of audio signal. Because the second section of audio signal and the fourth section of audio signal are obtained by collecting the second voice, the audio signal with higher intensity in the second section of audio signal and the fourth section of audio signal is the audio signal with better effect on collecting the second voice. Then if the intensity of the fourth segment of audio signal is greater than the intensity of the second segment of audio signal, which indicates that the second microphone is better for capturing the second speech than the first microphone, the processing module may determine the fourth segment of audio signal as the second audio signal.
S302: the processing module determines a time parameter of the first audio signal and a time parameter of the second audio signal.
After determining the first audio signal and the second audio signal, the processing module may obtain a time parameter of the first audio signal and a time parameter of the second audio signal. In the embodiment of the present application, the time parameter may include a start time of the audio signal and an end time of the audio signal. Then, in determining the time parameter of the first audio signal and the time parameter of the second audio signal, the processing module may determine a start time of the first audio signal, an end time of the first audio signal, a start time of the second audio signal, and an end time of the second audio signal by Voice Activity Detection (VAD) method.
S302: the processing module determines the interaction waiting time of the voice interaction device according to the time parameter of the first audio signal and the time parameter of the second audio signal.
As can be appreciated from the foregoing description, the interaction latency of the voice interaction device may be the time interval from after the user issues a voice command to when the voice interaction device begins to respond to the user's voice command. After determining the end time of the first audio signal and the start time of the second audio signal, the processing module may determine the end time of the first audio signal as a start time of the interaction latency and the start time of the second audio signal as an end time of the interaction latency. The difference between the start time of the second audio signal and the end of the first audio signal is the interaction latency of the voice interaction device.
In the time determination method provided by the embodiment of the application, the preset first voice can be played through the sound source, so that the voice interaction device responds according to the preset first voice, and plays the second voice. The audio acquisition module arranged between the sound source and the voice interaction equipment can acquire the audio signals generated in the test process to obtain a first audio signal corresponding to the first voice and a second audio signal corresponding to the second voice. Therefore, the first audio signal corresponding to the first voice represents the voice instruction sent by the sound source, and the second audio signal corresponding to the voice represents the response of the voice interaction equipment to the voice instruction. Therefore, according to the time parameter of the first audio signal and the time parameter of the second audio signal, the waiting time before the voice interaction device sends out a response after receiving the voice instruction, namely the interaction waiting time, can be determined. Therefore, by deploying the sound source and the audio acquisition module, the automatic test of the interaction waiting time of the voice interaction equipment can be realized. Compared with the traditional manual testing method, on one hand, the testing accuracy can be improved, and on the other hand, manpower and material resources can be saved.
