| Abstract(in English) | In this report, new acoustic models made by mixing probabilistic distributions with various precision are proposed. The proposed models can prevent phonetic confusion among precise phonetic models caused by acoustic variations in spontaneous speech, while keeping the advantage of precise model that can deal with acoustic variations caused by phonetic environment. Distributions in the proposed models are taken from both precise cotext-dependent(CD)model and another rough model, such as context-independent model. By using distributions from rough model, a model can match acoustic features which don't fit the precise model because of variations due to spontaneity. Experiments on spontaneous speech for hotel reservation task indicated that some of the proposed models can reduce error rate with CD model by around 1/10. |
