  • Patent number: 4044204
    Abstract: A speech signal-in-noise enhancement system which separates the voiced-unvoiced portions of speech, detects and extracts the voiced fundamental pitch and uses that data to control the band-pass center frequencies of a bank of filters so that the filters pass the harmonics of the fundamental pitch. The output of these filters is summed to form a composite signal representative of voiced speech. Unvoiced speech is separately passed to the summer.
