Abstract
Project is bent on speech signal processing, its parametrization and using this parameters in robust speech recognition by HMM net. Main part to use non-linear spectral smoothing, gain detection of this smoothing on recognizer robustness, compare this method with another used method and possibility to use this algorithm in recognizers with more inner states nets.
