Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that the terms "first," "second," and the like as used herein may be used herein to describe various data, but the data is not limited by these terms. These terms are only used to distinguish one datum from another. For example, a first usage scenario may be referred to as a second usage scenario, and similarly, the second usage scenario may be referred to as the first usage scenario, without departing from the scope of the present application. The first usage scenario and the second usage scenario are both usage scenarios, but they are not the same usage scenario.
FIG. 1 is a flow diagram of a method for audio signal processing in one embodiment. The audio signal processing method in this embodiment is described by taking an example of the audio signal processing method running on an electronic device. As shown in fig. 1, the audio signal processing method includes steps 102 to 106.
The audio signal is a frequency and amplitude variation information carrier with regular sound waves of voice, music and sound effects. The input audio signal is input by a user through the audio acquisition device when the user uses the electronic equipment to record sound. The audio acquisition device may be a microphone or the like. The user interaction information corresponding to the audio signal refers to information generated in the electronic equipment when the user inputs the audio signal. For example, the user interaction information may be at least one of motion data and a trigger manner corresponding to the step of acquiring the input audio signal, but is not limited thereto. The motion data may be at least one of gyroscope data and acceleration data, but is not limited thereto.
Specifically, the electronic device acquires an input audio signal through the audio acquisition device in response to an audio input operation, and acquires corresponding user interaction information when acquiring the input audio signal.
And step 104, determining a target user use scene corresponding to the audio signal according to the user interaction information.
Wherein the user usage scenario includes a first usage scenario and a second usage scenario. A first distance between the user and the electronic device characterized by the first usage scenario is greater than a second distance between the user and the electronic device characterized by the second usage scenario. For example, the first usage scenario may be a far-field usage scenario and the second usage scenario may be a near-field usage scenario. The target user usage scenario is either a first usage scenario or a second usage scenario.
Specifically, the electronic device may determine a target user usage scenario corresponding to the audio signal according to at least one of the motion data and the trigger manner corresponding to the step of acquiring the input audio signal.
And 106, determining a target adjusting parameter value of the audio signal according to the use scene of the target user, and performing corresponding signal adjusting processing on the audio signal based on the target adjusting parameter value to obtain the target audio signal.
The target adjusting parameter value may be at least one of, but not limited to, an adjusting multiple, an adjusting phase value, and an adjusting pitch frequency value. And each target user use scene has a corresponding target adjusting parameter value. The target adjusting parameter values corresponding to the target user use scenes are different. For example, the adjustment multiple corresponding to the first usage scenario is 1.5 times, and the adjustment multiple corresponding to the second usage scenario is 0.8 times. The target audio signal is an audio signal obtained by performing signal conditioning on an input audio signal.
Specifically, the electronic device determines a target adjustment parameter value of the audio signal according to the target user usage scenario. And the electronic equipment carries out corresponding signal conditioning processing on the audio signal based on the target conditioning parameter value to obtain a target audio signal. For example, the electronic device determines that the target user usage scenario is the first usage scenario, then the corresponding target adjustment parameter value is 1.5 times, then the electronic device increases the audio signal by 1.5 times.
In this embodiment, the electronic device performs speech recognition processing on the target audio signal to obtain a speech recognition result.
In the audio signal processing method in this embodiment, by acquiring the input audio signal and the user interaction information corresponding to the audio signal, a target user usage scenario corresponding to the audio signal is determined according to the user interaction information, that is, a voice input performed by a user in what scenario is distinguished; and the adjusting parameter value of the audio signal is determined according to the use scene of the target user, the audio signal under different scenes can be processed in a targeted manner, the accuracy of audio signal processing is improved, and the condition of error identification of the audio signal is reduced.
In one embodiment, the user interaction information includes motion data. Determining a target user usage scenario of an audio signal according to user interaction information, comprising: when the variation amplitude of the motion data in the preset time length is in a preset range, determining a target user usage scene of the audio signal as a first usage scene; and when the variation amplitude of the motion data in the preset time length is not in the preset range, determining that the target user usage scene of the audio signal is a second usage scene.
The electronic equipment comprises a motion detection device. The motion detection means may detect motion data acting on the electronic device. The motion detection means may be a gyroscope or an accelerometer, etc. Wherein the gyroscope is an angular motion detection device. When the electronic device includes a gyroscope, the motion data may specifically be angular velocity data. When the electronic device includes an accelerometer, the motion data may specifically be acceleration data. The motion data may be at least one of acceleration data and gyroscope data, but is not limited thereto. The preset time period refers to a time period preset on the electronic device, and may be, for example, 1 second, 2 seconds, 3 seconds, 1 minute, or the like, without being limited thereto. The preset range is used to represent a shaking range of the motion data. The change range of the motion data represented in the preset range is small, and the change range of the motion data not represented in the preset range is large.
Specifically, when the variation range of the motion data in the preset duration is within the preset range, it is indicated that the variation range of the motion data in a period of time of the audio input is small, that is, the electronic device may be in a stationary state, and then the target user usage scene corresponding to the audio signal is determined to be the first usage scene. And the first usage scenario may be referred to as a far-field usage scenario. When the variation amplitude of the gyroscope within the preset time length is not within the preset range, it is indicated that the variation amplitude of the motion data within a period of time of the audio input is large, that is, the electronic device may be in a motion state, and then the target user usage scene corresponding to the audio signal is determined to be a second usage scene. And the second usage scenario may be referred to as a far-field usage scenario. The electronic equipment is taken as a mobile phone, the preset time length is 3 seconds, and the change amplitude is 0-0.1, when the change amplitude of the motion data is 0-0.05 within 3 seconds, it indicates that the mobile phone is likely to be placed on a desk by a user, and the use scene is a far-field use scene. Conversely, when the variation range of the motion data within 3 seconds is 0-2, the mobile phone is likely to be held by the user, and the use scene is a near-field use scene.
In the audio signal processing method in this embodiment, when the variation amplitude of the motion data within the preset duration is within the preset range, it is determined as a first usage scenario; when the change amplitude of the motion data in the preset duration is not in the preset range, the second use scene is determined, then the scenes are distinguished according to the motion data, and the target adjusting parameter value is determined based on different scenes, so that the accuracy of audio signal processing can be improved, and the error recognition condition of the audio signal is reduced.
In one embodiment, the user interaction information includes a trigger corresponding to the step of acquiring the input audio signal. Determining a target user usage scenario of an audio signal according to user interaction information, comprising: when the triggering mode is triggered through a voice awakening mode, determining that a target user use scene of the audio signal is a first use scene; and when the triggering mode is triggered in a mode of touching the electronic equipment, determining that the target user usage scene of the audio signal is a second usage scene.
The triggering mode refers to an operation mode performed by a user before the input audio signal is acquired. For example, the triggering manner may be triggering by a voice wakeup manner or triggering by a touch electronic device. The voice wake-up mode is to wake up the audio signal input function in a voice mode. And a specific voice wake-up message is required to be able to wake up the audio signal input function. For example, the user may send out voice wake-up information such as "perform voice recognition", "i want to record cheer", and so on, and then the electronic device starts to acquire the input audio signal. The manner of touching the electronic device includes, but is not limited to, a virtual control of the touch electronic device, a physical control of the touch electronic device, a screen of the touch electronic device, and the like. For example, the manner of touching the electronic device may be long pressing the power key, clicking the hover ball, clicking the audio input control, but is not limited thereto.
Specifically, when the triggering mode is triggered by a voice wake-up mode, it indicates that the distance between the electronic device and the user is long, and then it is determined that the target user usage scenario of the audio signal is the first usage scenario. The first usage scenario may be referred to as a far-field usage scenario. When the triggering mode is triggered in a mode of touching the electronic device, it is indicated that the distance between the electronic device and the user is short, and then the target user usage scenario of the audio signal is determined to be a second usage scenario. The second usage scenario may be referred to as a near-field usage scenario. Taking the electronic device as a mobile phone as an example for explanation, when a user says "please perform voice recognition" to the mobile phone, that is, the user is triggered by a voice wake-up mode, it is explained that the distance between the user and the mobile phone is probably far, and at this time, the user is determined to be a far-field use scene. When a user triggers and acquires an input audio signal through a control on the touch mobile phone, the situation that the mobile phone is held by the user with high probability is determined as a near-field use scene.
According to the audio signal processing method in the embodiment of the application, when the audio signal is triggered in a voice awakening mode, namely, when the situation that the distance between a user and the electronic equipment is large is stated, the situation is determined to be a first use scene, when the audio signal is triggered in a touch electronic equipment mode, the situation that the distance between the user and the electronic equipment is small is stated, the situation is determined to be a second use scene, different scenes can be distinguished based on the triggering mode, the distance between the user and a mobile phone does not need to be directly acquired, a target adjusting parameter value is determined based on different scenes, the accuracy of audio signal processing can be improved, and therefore the situation of misidentification of the audio signal is reduced.
In one embodiment, the user interaction information includes motion data and a trigger corresponding to the step of obtaining the input audio signal. Determining a target user usage scenario of an audio signal according to user interaction information, comprising: when the triggering mode is triggered in a voice awakening mode and the variation amplitude of the motion data in the preset time length is in a preset range, determining a target user use scene of the audio signal as a first use scene; and when at least one condition that the triggering mode is triggered in a mode of touching the electronic equipment and the variation amplitude of the motion data in the preset time length is not in the preset range is met, determining the target user usage scene of the audio signal as a second usage scene.
Specifically, when the triggering mode corresponding to the acquired input voice signal is triggered in a voice mode and the variation amplitude of the motion data in the preset time length is within the preset range, it indicates that the electronic device is placed on a stable place such as a desk at a high probability and the distance between the electronic device and the user is far at a high probability, and then the target user usage scenario of the audio signal is determined to be the first usage scenario. When the triggering mode is triggered in a mode of touching the electronic device, or the variation amplitude of the motion data in the preset time length is not in the preset range, or the triggering mode is triggered in a mode of touching the electronic device and the variation amplitude of the motion data in the preset time length is not in the preset range, it is indicated that the electronic device is held by the user with a high probability, that is, the distance between the electronic device and the user is close to the high probability, and then the target user usage scene of the audio signal is determined to be a second usage scene. For example, when the user says "please perform voice recognition" to the electronic device, and the variation amplitude of the motion data of the electronic device within the preset time length is within the preset range, that is, when the electronic device is in a static state, the target user usage scenario of the audio signal is determined to be the first usage scenario. And when the step of acquiring the input audio signal is triggered by the user through the control of the touch electronic device, it indicates that the distance between the user and the electronic device is not too far, and the user is determined to be the second usage scenario.
In this embodiment, as shown in fig. 2, a scene diagram of a first usage scene in one embodiment is shown. Included in fig. 2 are an electronic device 210, a desk 220, a voice wake up mode 220, and a user 230. And the electronic device 210 may be placed on the table 220, at this time, the variation range of the motion data within the preset time length is within the preset range, so that the target user usage scenario may be determined as the first usage scenario. The user 230 may trigger the step of acquiring the input audio signal through the voice wake-up mode 220, and at this time, the distance between the user 230 and the electronic device 210 is likely to be relatively far, so that the target user usage scenario may be determined as the first usage scenario. Moreover, when the input audio signal is triggered and acquired through the voice wake-up mode 220 and the variation amplitude of the motion data in the preset time length is within the preset range, the target user usage scenario of the audio signal can also be determined as the first usage scenario. Namely, when the mobile phone is stably placed on the table top and is awakened by voice, the distance between the mobile phone and the user is considered to be relatively long, and a relatively large signal enhancement amplitude (namely a target adjustment parameter value) can be set.
In this embodiment, as shown in fig. 3, a scene diagram of a second usage scene in one embodiment is shown. A user 310 and an electronic device 320 are included in fig. 3. Then, when the user 310 holds the electronic device 320, the step of acquiring the input audio signal is generally triggered by touching the electronic device, and the variation range of the motion data within the preset time duration is generally large, so that it can be determined that the target user usage scenario of the input audio signal is the second usage scenario. Then the user is holding the handset to speak and the magnitude of the signal enhancement is limited to a lower level.
In the audio signal processing method in this embodiment, the motion data and the triggering manner corresponding to the step of acquiring the input audio signal are combined to determine the target user usage scenario of the electronic device, so that accuracy of scenario judgment can be improved, accuracy of audio signal processing can be improved, and false recognition of the audio signal can be reduced.
In one embodiment, performing corresponding signal conditioning processing on the audio signal based on the target conditioning parameter value to obtain the target audio signal includes: acquiring a reference adjusting parameter value of the audio signal; and when the reference adjusting parameter value is larger than the target adjusting parameter value, carrying out corresponding signal adjusting processing on the audio signal based on the target adjusting parameter value to obtain a target audio signal.
Wherein, the reference adjusting parameter value can be obtained by the existing voice adjusting algorithm. The target tuning parameter value may be a maximum multiple of a signal amplification.
Specifically, when the reference adjusting parameter value is larger than the target adjusting parameter value, the electronic device performs corresponding signal adjustment processing on the audio signal based on the target adjusting parameter value to obtain a target audio signal. For example, the target user usage scene is a first usage scene, the target adjustment parameter corresponding to the first usage scene is M, the input audio signal is calculated by the adaptive signal enhancement algorithm to obtain a reference adjustment parameter value X, and when X > M, the audio signal is subjected to corresponding signal adjustment processing according to M to obtain the target audio signal. Or, the target user usage scene is a second usage scene, the target adjustment signal corresponding to the second usage scene is N, the input audio signal is calculated by the adaptive signal enhancement algorithm to obtain a reference adjustment parameter value X, and when X is greater than N, the audio signal is subjected to corresponding signal adjustment processing according to N to obtain the target audio signal.
In the audio signal processing method in this embodiment, when the reference adjusting parameter value is greater than the target adjusting parameter value, corresponding signal adjustment processing is performed on the audio signal based on the target adjusting parameter value to obtain the target audio signal, the signal adjusting parameter value is limited, and a smaller value is taken, so that when the user does not speak, and another person nearby is in a chat scene, a smaller adjusting parameter value can be obtained, the accuracy of audio signal processing is improved, the chat content of another person is prevented from being entered, and the situation of misidentification of the audio signal is reduced.
In one embodiment, the audio signal processing method further includes: and when the reference adjusting parameter value is smaller than or equal to the target adjusting parameter value, carrying out corresponding signal adjusting processing on the audio signal based on the reference adjusting parameter value to obtain a target audio signal.
Specifically, when the reference adjusting parameter value is smaller than or equal to the target adjusting parameter value, the audio signal is subjected to corresponding signal adjusting processing based on the reference adjusting parameter value, and a target audio signal is obtained. For example, the target user usage scene is a first usage scene, the target adjustment parameter corresponding to the first usage scene is M, the input audio signal is calculated by the adaptive signal enhancement algorithm to obtain a reference adjustment parameter value X, and when X is less than or equal to M, the audio signal is subjected to corresponding signal adjustment processing according to X to obtain the target audio signal. Or, the target usage scene is a second usage scene, the target adjustment signal corresponding to the second usage scene is N, the input audio signal is calculated by the adaptive signal enhancement algorithm to obtain a reference adjustment parameter value X, and when X is less than or equal to N, the audio signal is subjected to corresponding signal adjustment processing according to X to obtain the target audio signal.
In the audio signal processing method in this embodiment, when the reference adjusting parameter value is less than or equal to the target adjusting parameter value, corresponding signal adjustment processing is performed on the audio signal based on the reference adjusting parameter value to obtain the target audio signal, and then corresponding signal adjustment processing is performed on the audio signal based on a smaller value of the reference adjusting parameter value and the target adjusting parameter value, so that an effect of correctly identifying the input audio signal can be achieved, and when the user does not speak, and other people nearby are in a chat scene, a smaller adjusting parameter value can be obtained, accuracy of audio signal processing is improved, entry of chat contents of other people is avoided, and a situation of misidentification of the audio signal is reduced.
In one embodiment, the user usage scenario includes a first usage scenario and a second usage scenario, wherein a distance between the user and the electronic device characterized by the first usage scenario is greater than a distance between the user and the electronic device characterized by the second usage scenario; adjusting the parameter value comprises adjusting multiple;
determining a target adjusting parameter value of an audio signal according to a target user usage scene, and performing corresponding signal adjusting processing on the audio signal based on the target adjusting parameter value to obtain a target audio signal, including:
when the target user usage scene is a first usage scene, determining that a target adjusting parameter value of the audio signal comprises a first adjusting multiple corresponding to the first usage scene, and performing corresponding signal adjusting processing on the audio signal based on the first adjusting multiple to obtain a target audio signal;
when the target user usage scene is a second usage scene, determining that a target adjustment parameter value of the audio signal comprises a second adjustment multiple corresponding to the second usage scene, and performing corresponding signal adjustment processing on the audio signal based on the second adjustment multiple to obtain a target audio signal; the first adjustment factor is greater than the second adjustment factor.
