Abstract

The invention relates to a sound source direction determination method and device, electronic equipment and a storage medium, and belongs to the technical field of audio processing. The method comprises the steps that based on M pickup directions, M voice signals are picked up, each voice signal corresponds to one pickup direction, the M voice signals are used for waking up a terminal, and M is an integer larger than 1; based on the M voice signals, M wake-up parameters and an initial sound source direction are determined, and the M wake-up parameters are used for representing the contribution degree of waking up the terminal by the M voice signals; and adjusting the initial sound source direction based on the M wake-up parameters and the M pickup directions to obtain a target sound source direction. The method can improve the accuracy of determining the target sound source direction.

Description

technical field [0001] The present application relates to the technical field of audio processing, and in particular to a sound source direction determination method, device, electronic equipment and storage medium. Background technique [0002] At present, the terminal has a voice recognition function, which can recognize a voice control command in a voice signal of a user, and then execute an operation corresponding to the voice control command. In order to save power consumption, the terminal is in a dormant state before recognizing the voice control command. After receiving the wake-up command, it wakes up and collects the voice signal, and then recognizes the voice signal. In order to improve the clarity of the collected voice signal, the terminal may use the voice signal of the wake-up command to locate the direction of the sound source, and then collect the voice signal based on the sound source direction. [0003] In the related art, when the user wakes up the termi...
