Abstract
The wavelet analysis can improve speech recognition performance through many approaches. First, it can be used to remove noise, and consequently the recognition process may perform better. Alternatively, wavelet-based features can be added to other successful features to improve recognition performance. Third, wavelets can serve as an activation function in neural-networks employed for speech recognition. Hybrid methodology may comprise a mix of one or more approaches.
