| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | TANDEM-STRAIGHT, an F0-adaptive spectral envelope extraction procedure was applied to cross synthesis VOCODER, which synthesizes sounds by mixing features of two input sounds, such as speech and musical instruments or animal voices. A set of tests with FIR implementation of time-varying filter illustrated potential improvements of intelligibility by using STRAIGHT spectrum of speech sounds, but at the same time, introduced deterioration of instruments' characteristic timbre. A new cross synthesis framework using deviation spectrum of speech sounds and minimum phase implementation of time varying filter was proposed to solve this problem. Preliminary tests suggested that the proposed method reduces this deterioration while preserving intelligibility. |
