Abstract

The embodiment of the present invention discloses a method, device, electronic equipment, and storage medium for acquiring the amplitude of a sound range, wherein the method includes: collecting voice data of a target sound range in real time, and the voice data includes a plurality of sampling points corresponding to Audio signal; storing 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; The current sound zone amplitude of the target sound zone is calculated according to the stored amplitudes of all audio signals. The embodiment of the present invention can accurately obtain the amplitude of the sound area, thereby accurately locating the source sound area of ​​the voice data according to the amplitude of the sound area, thereby solving the problem of false wake-up caused by insufficient isolation of the four-sound area, and correcting the false wake-up of the speech engine Provide amplitude data basis, and the amount of calculation is small, saving system resources.

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...
