The separability analysis of pitch parameters in speaker recognition

Abstract

Aseparability research of prosodic parameters in speaker recognition is studied.The space distribution of the prosodic parameters is drawn using the mean and variance of the speaker pitch parameters,through which the separability of the speaker is obvious.We do a speaker identification experiment with a small corpus,and the experiment results show that speaker identification based on the prosodic parameters is possible. The first-level decision using the prosodic parameters can reduce the candidate corpus effectively,demonstrating the practicability of the pitch parameters.
