Abstract

The disclosure provides a sound source orientation method, device and system, and relates to the technical field of sound signal processing. The method includes obtaining time delay estimates for each group of M microphones, wherein M≥2, 1≤m≤M, and each group of microphones includes two microphones; respectively calculating the relative Carry out coordinate transformation on the relative horizontal angle of each group of microphones based on the relative horizontal angle of each group of microphones, transform it into a preset coordinate system, and obtain the coordinate transformation horizontal angle φ m ;According to the transformation horizontal angle φ m and the time delay estimate is calculated according to the first formula to estimate the horizontal angle

Description

technical field [0001] The present disclosure relates to the field of acoustic signal processing, and in particular, to a sound source orientation method, device and system. Background technique [0002] With the continuous development and application of artificial intelligence technology, traditional microphones will be replaced by microphone arrays. The microphone array can clearly pick up far-field voice signals, filter ambient noise, and even extract target sounds from noisy environments. Compared with traditional microphones, the biggest advantage of the microphone array is that it makes full use of the spatial information of the signal, so as to obtain high-quality speech enhancement effects. [0003] In speech enhancement based on microphone array, sound source orientation plays a pivotal role. Fast and precise sound source orientation is a prerequisite for high-quality speech enhancement results. Orientation accuracy and tracking speed will directly determine the ...
