Research Abstract |
To improve speech recognition performance in adverse conditions, a noise compensation method is proposed and investigated that applies a transformation in the spectral domain whose parameters are optimized based on likelihood of speech GMM modeled on the feature domain. Experimental results show that the proposed method is able to work in real-time and it is effective to reduce noise effects.
