Perceptually Weighted Mel-Cepstrum Analysis of Speech Based on Psychoacoustic Model Hongwu YANG Dezhi HUANG Lianhong CAI Publication IEICE TRANSACTIONS on Information and Systems Vol.E89-D No.12 pp.2998-3001 Publication Date: 2006/12/01 Online ISSN: 1745-1361 DOI: 10.1093/ietisy/e89-d.12.2998 Print ISSN: 0916-8532 Type of Manuscript: LETTER Category: Speech and Hearing Keyword: weighted mel-cepstral analysis, auditory properties, Full Text: PDF(138.1KB)>>
Summary: This letter proposes a novel approach for mel-cepstral analysis based on the psychoacoustic model of MPEG. A perceptual weighting function is developed by applying cubic spline interpolation on the signal-to-mask ratios (SMRs) which are obtained from the psychoacoustic model. Experiments on speaker identification and speech re-synthesis showed that the proposed method not only improved the speaker recognition performance, but also improved the speech quality of the re-synthesized speech. | ||||||||||
