Speaker identification and verification by combining MFCC and phase information

S Nakagawa, L Wang, S Ohtsuka - IEEE transactions on audio …, 2011 - ieeexplore.ieee.org
In conventional speaker recognition methods based on Mel-frequency cepstral coefficients (MFCCs),
phase information has hitherto been ignored. In this paper, we propose a phase …

[PDF][PDF] Speaker recognition by combining MFCC and phase information

S Nakagawa, K Asakawa, L Wang - spectrum, 2007 - Citeseer
In conventional speaker recognition method based on MFCC, the phase information has
been ignored. In this paper, we proposed a method that integrates the phase information on a …

[PDF][PDF] Relative phase information for detecting human speech and spoofed speech.

L Wang, Y Yoshida, Y Kawakami, S Nakagawa - INTERSPEECH, 2015 - isca-archive.org
The detection of human and spoofed (synthetic/converted) speech has started to receive
more attention. In this study, relative phase information extracted from a Fourier spectrum is …

Learning affective representations based on magnitude and dynamic relative phase information for speech emotion recognition

L Guo, L Wang, J Dang, ES Chng, S Nakagawa - Speech Communication, 2022 - Elsevier
