Speaker normalization algorithms for very-low-rate speech coding

Abstract: We use speaker normalization for vocoding the speech of a new input speaker by using a speaker dependent segment vocoder operating at a very-low bit rate, below 300 b/s. The normalization consists of a spectral transformation, applied on the spectral parameter vector of the reference speaker, which should improve the match between the reference and input speakers. The optimal spectral transformation is determined by an iterative algorithm that is guaranteed to converge to a local optimum, i.e., the quantizatio… Show more

“…One method is to select the most suitable codebook for a new speaker from multiple speaker dependent codebooks [6]. Another is to adapt one codebook to a new speaker using linear transformation [7]. In the former method, the performance depends on the type and number of selected speakers used for designing the codebooks.…”
