| Abstract(in English) | One of the key issues for adaptation algorithms is to modify a large number of parameters with only a small amount of adaptation data. Speaker adaptation techniques try to obtain near speaker dependent (SD) performance with only small amounts of specific data and are often based on initial speaker independent (SI) recognition systems. In this paper, we introduce an aspect model into an acoustic model for rapid speaker and environment adaptation. A formulation of probabilistic latent semantic analysis (PLSA) is extended to continuous density HMM. We carried out isolated word recognition experiment, and the results was compared to that of MAP and MLLR. |
