| Abstract: | In this paper we address the application of a denoising algorithm based on wavelet package decomposition and quantile noise estimation to noise suppression for automatic speech recognition. The denoising algorithm is adapted to suit the different requirements in machine recognition, as compared to human perception, and is tested in combination with state-of-the-art speech recognition systems. The results show, that, if the proposed algorithm is integrated with the recognition system---including the training process---a performance comparable to recent high-quality noise suppression methods is achieved. | ||
