Title:
SOUND SOURCE LOCALIZATION METHOD AND APPARATUS BASED ON MICROPHONE ARRAY, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/257499
Kind Code:
A1
Abstract:
A sound source localization method and apparatus based on a microphone array, and a terminal and a computer-readable storage medium. The method comprises: acquiring a voice signal from a microphone array module (S110); pre-processing the voice signal, and determining target data including sound source information (S120); obtaining sound source orientation information according to the target data and by means of orientation processing (S130); obtaining, according to the sound source orientation information, a control signal for controlling an LED orientation display module (S140); and sending the control signal to the LED orientation display module, so that the LED orientation display module displays the orientation of a sound source (S150). By means of the sound source localization method, useless voice signals, such as noise and silence, can be effectively excluded, so as to obtain target data including sound source information; and a control signal can be obtained according to sound source orientation information, and the orientation of a sound source is intuitively displayed by using an LED orientation display module. Therefore, a sound source localization system can quickly and intuitively display the orientation of a sound source.
