Embodiment 1

[0026] figure 1 It is a flow chart of a method for obtaining the amplitude of a sound zone provided by Embodiment 1 of the present invention. This embodiment is applicable to vehicle-mounted terminals that need to obtain the amplitudes of different sound zones on the vehicle, so as to recognize voice signals according to the amplitude of each sound zone In the case of the source sound zone, the method can be executed by a corresponding sound zone amplitude acquisition device, which can be implemented in software and / or hardware, and can be configured on electronic equipment, such as a vehicle-mounted terminal.

[0027] Such as figure 1 As shown, the sound range amplitude acquisition method provided in the embodiment of the present invention may include:

[0028] S110. Collect voice data in the target sound area in real time, where the voice data includes audio signals corresponding to multiple sampling points.

[0029] Generally, the whole vehicle can be divided into four so...

Embodiment 2

[0039] figure 2 It is a schematic flowchart of a method for acquiring the amplitude of a sound region provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments, such as figure 2 As shown, the sound range amplitude acquisition method provided in the embodiment of the present invention may include:

[0040] S210. Collect voice data in the target sound zone in real time, where the voice data includes audio signals corresponding to multiple sampling points.

[0041] S220. Insert the audio signals corresponding to the multiple sampling points into the pre-created container in sequence, and bind the corresponding insertion time stamp to the amplitude of each audio signal during the insertion process.

[0042] Since the voice data collected by the vehicle-mounted terminal is time-sensitive, the voice data acquired some time ago is meaningless for the calculation of the current range amplitude. Therefore, it is necessary ...

Embodiment 3

[0053] image 3 It is a schematic structural diagram of a device for obtaining sound range amplitude provided by Embodiment 3 of the present invention. Such as image 3 As shown, the device includes:

[0054] Acquisition module 310, is used for collecting the voice data of target sound zone in real time, and described voice data comprises the corresponding audio signal of a plurality of sampling points;

[0055] The storage module 320 is configured to store the audio signal in the following manner: comparing the amplitude of the current audio signal to be stored with the amplitude of each stored audio signal, and selecting whether to store the current audio signal according to the comparison result audio signal;

[0056] The sound zone amplitude calculation module 330 is configured to calculate the current sound zone amplitude of the target sound zone according to the amplitudes of all the stored audio signals.

[0057] In this embodiment, the storage module stores the aud...

Abstract

The embodiment of the invention discloses a sound area amplitude acquisition method and device, an electronic device and a storage medium, wherein the method comprises the steps of collecting the voice data of a target sound area in real time, wherein the voice data comprises the audio signals corresponding to a plurality of sampling points; storing the audio signal by comparing the amplitude of the current audio signal to be stored with the amplitude of each stored audio signal, and selecting whether to store the current audio signal or not according to the comparison result; and calculatingthe current sound area amplitude of the target sound area according to the amplitudes of all the stored audio signals. According to the embodiment of the invention, the amplitude of the sound area canbe accurately obtained, so that the source sound area of the voice data is accurately positioned according to the amplitude of the sound area, the problem of false awakening caused by insufficient isolation of the four sound areas is solved, an amplitude data basis is provided for correcting false awakening of a voice engine, the calculation amount is small, and the system resources are saved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle systems, and in particular, to a method, device, electronic equipment, and storage medium for acquiring a sound range amplitude. Background technique [0002] Traditional in-vehicle voice recognition technology solutions are designed around the driver alone. The angle of the front-end microphone is designed to align with the driver's seat. Traditional in-vehicle navigation, music, phone and other application functions are also designed around the driver. , only need to acquire and recognize the driver's voice signal. With the increase of application requirements, the car four-tone zone solution has gradually entered people's field of vision. The car four-tone zone solution is a car voice system that can be used by all people in the car. The whole car is divided into four sound zones, front, rear, left, and right, and can independently pick up the sound of the four sound zon...
