Abstract (en)
[origin: EP0594480A1] The method of the invention consists in: - detecting a voiced frame; - searching for the noise frames preceding this voiced frame; - constructing an auto-regressive model of the noise and a mean noise spectrum; - whitening the frames preceding the voicing; - searching for the actual start of speech in the whitened frames; - ridding the voiced frames of noise and parametrising them; and - searching for the actual end of speech.
