Abstract

Differentiated voice is the common check material form in judicial voice testing field. There are many factors that lead to the voice variation; the more common approach is the voice channel, Stylistic variation, disguise and reverberation etc. The variation brings about changes in hearing, atlas and parameters for voice, which brings about many difficulties to speaker identification. According to the variety of speech variation mode we explore the variation of the internal principle, and get fundamental frequency variation rule before and after voice change of multiple corpuses by analyzing map and data. The results show that the fundamental frequency before and after voice variation exists a linearity relationship, we can realize speaker identification in voice variation field through comparing Chinese pitch pattern.
