| Zusammenfassung: | A method and detector for providing a noise resistant utterance detector is provided by extracting a noise estimate ( 15 ) to augment the signal-to-noise ratio of the speech signal, inverse filtering ( 17 ) of the speech signal to focus on the periodic excitation part of the signal and spectral reshaping ( 19 ) to accentuate separation between formants. |
