Study of line spectrum pair frequencies for speaker recognition

Four varieties of line spectrum pair (LSP) frequencies for speaker recognition applications and their corresponding performances are studied. The four varieties are all-LSP frequencies, odd or even line spectrum frequencies, the mean of adjacent LSP frequencies, and the difference of adjacent LSP frequencies. A speaker-based vector quantization approach is used in the evaluation. The results show that each variety of LSP frequencies has a very high accurate rate.<
