| Abstract(in English) | A text-independent speaker recognition method using the individual information in the harmonic structure of LP-residual spectrum is proposed. The feature parameter extracted from harmonic structure is obtained by dividing LP-residual spectrum to subbands and parameterizing the power difference of spectrum in each subband. A VQ-based text-independent speaker identification experiments are conducted using speech data uttered by 25 male and 25 female speakers over 1 year. Experimental results show that feature parameter extracted from harmonic structure gives poor identification rate when it is used alone. However, it decreases identification errors over 11% by combining it to LPC cepstral coefficients. |
