| Abstract(in English) | Speech recognition has been an active research area for many years, and nowadays, it is being used in many practical applications. However, the recognition performance is often seriously degraded by noise and reverberation present in recording environments. One promising approach to solve this problem is feature enhancement, which attempts to restore clean feature vectors using a GMM of clean speech. Mean-while, in many recent applications including those to mobile devices, it is easy to collect target user's speech data recorded in various environments. However, how to exploit these data for improving the performance of a speech recognizer that performs feature enhancement is an open question. This study experimentally compares different methods for combining MAP adaptation of the clean speech GMM and MLLR adaptation of the recognizer's acoustic model. |
