A method for detecting the start and end of speech from a noisy signal including the steps of: detecting a voiced frame; searching for noise frames preceding this voiced frame; constructing an autoregressive model of the noise and a mean noise spectrum; bleaching the flames preceding the voicing, searching for the actual start of speech in the bleached frames; removing the noise from the voiced frames and parameterizing them; and searching for the actual end of speech.
