Noise Effect on the Correlation between Fundamental Frequency (F0)

Difference and Speaker Identification Accuracy

Abstract

In this study, 30 native Japanese speakers were examined using two types of noise with three levels of SNR (SNR = ∞,0 dB,−10 dB), and five unknown speakers were asked to di!erentiate between two types of speech. Based on the experiment results, a linear single regression analysis was conducted to analyze the relationship between the fundamental frequency (F0) di!erence between stimulus pairs and the identification rate in the presence and absence of noise, and the e!ect of the degree of noise. The parameters estimated by the linear single regression analysis confirmed the possibility that F0 contributes more to speaker recognition with noise than without noise, and that the change in the contribution of F0 to speaker recognition with the presence or absence of noise may be small.
