Development of the speech recognition technology undernonstationary noisy environments using an adaptation method

適応処理による非定常雑音下での音声認識技術の開発

Research overview:
this research aims at developing the noise-robust speech recognition technology under nonstationary noisy environments like factories,in which it is difficult to recognize noisy speech precisely because of low SNR (signnal-to-noise ratio) and spectral-pattern deformation. This research improves the rerformance of noisy speech recognition by using the parameter weighted in reliable voiced sound periods for the pattern matching based on DTW (dynamic time warping).
