Speaker adaptation by hierarchical EigenVoice

  title={Speaker adaptation by hierarchical EigenVoice},
  author={Yoshifumi Onishi and Ken-ichi Iso},
We propose a novel speaker adaptation method, Hierarchical EigenVoice (HEV). This method extends the EigenVoice [ I ] through clustering the Gaussian components of HMMs into a hierarchical tree structure. It enables to autonomously control a number of adaptation parameters (model complexity) depending on the amount of adaptation utterances from a new speaker. The experimental results of Japanese large vocabulary continuous speech recognition confirmed the significant performance increase in all… CONTINUE READING
