With the development of voice interaction technology, more and more home terminal devices have a voice interaction function. By using the voice interaction function, the user can control the terminal devices to perform corresponding operations, such as starting, stopping and the like.
At present, for voice interaction of a handheld device, a user is usually required to press a key or input a wake-up word to trigger the handheld device to start a voice interaction function. In order to improve the user experience, besides the two ways, a way of lifting the wake-up is also defined. For example, a user may pick up the remote control from a desktop and trigger a voice interaction function of the remote control.
However, in the lift-off wake mode, if the user is simply picking up the handheld device, there is no intent to interact with the voice. At this time, if the user is speaking at the same time, the condition of wrong reception is easy to occur, resulting in poor user experience.
In order to solve the above problems, the present application provides a sound reception system of a handheld device, such as a sound reception system framework diagram of a handheld device shown in fig. 2. The system includes at least a user layer, a sensing layer, and a system layer. The user layer is a hierarchy for the user to perform input operation to input signals. The sensing layer is provided with various sensors for sensing the operation of a user and converting the operation of the user into a hierarchy of related signals.

For example, when the handheld device is a remote controller, the main chip may be disposed in the display device or in the remote controller. The embodiment of the application uses the main chip to be arranged in the handheld device for the explanation of the scheme. It should be noted that the handheld device provided in the present application may be any terminal such as a mobile phone, a wearable device, an AR (Augmented Reality)/VR (Virtual Reality) device, a tablet Computer, a notebook Computer, a UMPC (Ultra-mobile Personal Computer), a netbook, a PDA (Personal Digital Assistant), and the like, and the embodiment of the present application is not limited thereto.

Further sensing layers may include a sound collector and a screen lift sensor. The sound collector is used for collecting voice signals input by a user, and the screen lifting sensor is used for detecting whether the handheld device is picked up or not. The sound collector can be a microphone, and the screen lifting sensor can be an acceleration sensor.
An acceleration sensor is a sensor capable of measuring acceleration. The damper is generally composed of a mass block, a damper, an elastic element, a sensitive element, an adjusting circuit and the like. In the acceleration process, the sensor obtains an acceleration value by measuring the inertial force borne by the mass block and utilizing Newton's second law. Common acceleration sensors include capacitive type, inductive type, etc. according to the sensor sensing element. The acceleration sensor used in the embodiment of the present application is not limited, and for example, a three-axis acceleration sensor may be used.
If the handheld device is picked up by a user, acceleration changes can be detected by the acceleration sensor. The acceleration sensor generates a screen lifting signal according to the acceleration change and sends the screen lifting signal to the main chip. And after receiving the screen lifting signal, the main chip controls the sound collector to start. And after the sound collector is started, the sound collector starts to collect the voice signal input by the user.

And the main chip calculates the sound source angle between the user and the handheld device according to the voice signal. And if the sound source angle between the user and the handheld device is within the preset sound source angle range, representing that the user intends to perform voice interaction, and performing voice recognition processing on the collected voice signals. It should be noted that the speech recognition processing procedure belongs to the prior art, and the detailed description is not provided in this application. The processes of performing intention judgment and intention execution according to the recognition result after performing the voice recognition processing also belong to the prior art, and detailed explanation is not provided in the present application.
If the sound source angle between the user and the handheld device is not within the preset sound source angle range, the fact that the user does not intend to carry out voice interaction is indicated, and voice recognition processing is not carried out on the collected voice signals.
In some embodiments, the sound collector may be a microphone array including at least two microphones. Calculating a sound source angle between a user and the handheld device according to the voice signal, specifically:
fig. 3 is a schematic diagram of a sound source angle calculation method. In fig. 3, a far-field incident signal is a voice signal input by a user, and a wave front means that a spherical surface is formed from a sound source to a propagation direction when a sound wave propagates. From a long distance, the wave front can be regarded as a plane, and calculation is also convenient. P microphones 1, 2.. p-2, p-1, p are shown in fig. 3. The calculation formula of the time difference of the voice signals sent by the sound source reaching each microphone is as follows:
wherein p is the number of microphones, d is the distance between two adjacent microphones, and thetamIs the sound source angle between the user and the handheld device. As shown in fig. 4, the sound source angle may specifically be the angle between the user and the central axis of the handheld device. The matrix can be constructed according to the formula:
wherein x is1...xpIs the X-coordinate value, y, of the microphone1...ypAs a Y-coordinate value τ of the microphone12...τ(p-1)pIs the time difference of the arrival of the voice signal sent by the sound source at the two adjacent microphones. From this matrix, p sound source angle values can be obtained. And finally, calculating by using a least square method to obtain a final sound source angle value. Detailed description of the inventionThe process is prior art and is not described in detail in this application. In addition to the above-described sound source localization method using time difference of arrival, other sound source localization methods may be adopted in the embodiments of the present application. E.g., based on high resolution spectral estimation. The basic principle is to obtain the corresponding received energy size at each angle by using a spatial spectrum scanning mode. And further determining the angle of the received maximum energy as the angle of arrival of the sound source.
The preset sound source angle range in the embodiment of the present application may be set by a user according to experience. For example, the preset sound source angle is set to 90 ° ± 15 °, if the calculated sound source angle is within the range of 90 ° ± 15 °, it may be determined that the user intends to perform voice interaction. It may be that the user picks up the handheld device and places the microphone of the handheld device in a range of positions that are offset from side to side by no more than 15 deg. directly in front of the user's mouth. If the calculated sound source angle is not within the range of 90 ° ± 15 °, it may be determined that the user does not intend to perform voice interaction. It may be that the user simply picks up the handheld device but does not place the microphone of the handheld device directly in front of the user's mouth with a positional offset of no more than 15 left and right.
For example, as shown in FIG. 4, if the user is in the B position, where the sound source angle is 90, the user is directly in front of the handheld device. If the user is in the position A, the included angle between the user and the central axis of the handheld device is 10 degrees, the sound source angle is 90 degrees +/-10 degrees, and the user intention can be determined to carry out voice interaction. If the angle between the user and the central axis of the handheld device is 50 degrees when the user is at the position C, the angle of the sound source is 90 degrees +/-50 degrees, and the value of the angle is not within the preset angle range of the sound source. It may be determined that the user did not intend to engage in a voice interaction.
In some embodiments, if it is determined that the sound source angle is within the preset sound source angle range, it is further determined whether the voice activity detection result is an end. If the voice activity detection result is not finished, the voice activity detection result indicates that the user continues to input the voice signal. The sound collector continuously collects the voice signal input by the user. And finally, the main chip performs voice recognition processing according to the complete voice signal. If the voice activity detection result is end, it indicates that the user does not continue inputting the voice signal. And the main chip performs voice recognition processing according to the currently acquired voice signal.
Illustratively, the user inputs a voice signal "turn on the television" after picking up the remote controller. And the main chip of the remote controller judges that the sound source angle is within a preset sound source angle range, namely, the user is determined to have the voice interaction intention. At this time, the user continues to input the voice signal "jump to the center set", and the voice activity detection result is not ended at this time. The sound collector continues to collect the voice signal input by the user, and obtains a complete voice signal, namely, turning on the television and jumping to the central set. And finally, turning on a television for the completed voice signal, and jumping to a central set for voice recognition processing. If the user does not continue inputting the voice signal after the user is determined to have the voice interaction intention, the voice activity detection result is ended at the moment. And finally, performing voice recognition processing according to the current voice signal 'turn on television'.
In some embodiments, if the sound source angle is not within the preset sound source angle range, the collection of the voice signal input by the user is stopped regardless of whether the voice activity detection result is not finished or finished.
In some embodiments, if the sound source angle is within the preset sound source angle range and the handheld device has a display, the result of performing the voice recognition process on the voice signal is finally displayed on the display.
In some embodiments, if the sound source angle is not within the preset sound source angle range, after determining that it is not within the preset sound source angle range, controlling the screen of the display to be extinguished.
In some embodiments, if the controller receives the screen-up signal, the controller controls the sound collector to start up, but the sound collector does not collect the voice signal, and the prompting language "please speak again" can be displayed on the display, and meanwhile, an alarm sound is given to remind the user. And if the voice signal is not collected by the sound collector within the preset time period, determining that the user has no voice interaction intention, and controlling the display to extinguish the screen. And if the voice signal is collected by the sound collector within the preset time period, determining that the user has the voice interaction intention, and performing voice recognition processing on the collected voice signal.

And step two, after receiving the screen lifting signal, the controller controls the sound collector to start. The sound collector collects a voice signal input by a user and sends the voice signal to the controller.
And step three, the controller calculates the sound source angle between the user and the handheld device according to the voice signal.
And step four, if the sound source angle is within the preset sound source angle range, performing voice recognition processing on the voice signals.

and calculating the sound source angle between the user and the handheld device according to the distance between two adjacent microphones and the time difference of the two adjacent microphones in receiving the voice signals. Wherein the sound source angle is the angle between the user and the central axis of the handheld device
In some embodiments, if the sound source angle is within the preset sound source angle range, it is continuously determined whether the voice activity detection result is over. If the voice activity detection result is not finished, the voice collector still can continuously collect the voice signal input by the user. The controller continues to receive the voice signal and finally performs voice recognition processing on the complete voice signal. If the voice activity detection result is end, the voice collector can not collect the voice signal input by the user any more. The controller performs a voice recognition process on the current voice signal.
