| Abstract(in English) | This paper presents a new approach against environmental noise, an acoustic model adaptation technique based on the Taylor series. Using an HMM composition, a model containing noise should be composed from a speech model and a noise model each time when environmental noise changes. From the viewpoint of a "noise adaptation" approach, we modify an acoustic model "from one noise to another". This makes it possible to adapt the acoustic model at a low computation cost. In an HMM composition, non-linear conversion from cepstrum parameters is required. To accomplish a fast model adaptation, this paper uses first-order terms of the Taylor series. Based on the experimental results, we confirm a low computation cost for the adaptation processes, and the need for a small amount of noise data for the model adaptation. |
