METHOD AND SYSTEM FOR VOICE SEPARATION BASED ON DEGENERATE UNMIXING ESTIMATION TECHNIQUE

摘要

A method and system for voice separation based on DUET algorithm is disclosed. The method comprises: receiving signals from microphones; performing a Fourier transform on the received signals (S110); calculating a relative attenuation parameter and a relative delay parameter for each data point (S120); selecting a clustering range for the relative delay parameters based on a distance between the microphones and a sampling frequency of the microphones, clustering the data points within the clustering range for the relative delay parameters into subsets (S130), and performing an inverse Fourier transform on each subsets (S140). It provides an efficient and intelligent solution to deploy DUET on the software and/or hardware.
