Abstract

Abstract: Vocal tract length aligning was proposed for mandarin age voice conversion which transforms age speech into some required target age speech. In the method, the speech spectrum which has been pitch marked was warped in the frequency domain based on the warping factor and warping function while pitch was converted by linear transformation. The experimental results show that the effect of transforming old age speech into a young one is better than otherwise and that the average spectra distance of the former is markedly reduced.Meanwhile, age voice conversion is better for female voice than for male voice in effectiveness and naturalness.

Key words: age voice conversion, vocal tract length aligning, pitch marker, warping factor, warping function, linear transformation
