We are going to refer to the problem of speech recognition under noisy conditions, with medium size vocabularies of isolated words. We describe a method for feature extraction and the scores obtained with a HMM based recognizer. This method uses a combination of others two methods: the Short-time Modified Coherence and the spectral subtraction.
