  • System for suppressing rain noise
    Patent number: 8374855
    Abstract: A voice enhancement logic improves the perceptual quality of a processed signal. The voice enhancement system includes a noise detector and a noise attenuator. The noise detector detects and models the noise associated with rain. The noise attenuator dampens or reduces the rain noise from a signal to improve the intelligibility of an unvoiced, a fully voiced, or a mixed voice segment.
    Type: Grant
    Filed: May 19, 2011
    Date of Patent: February 12, 2013
    Assignee: QNX Software Systems Limited
    Inventors: Phillip A. Hetherington, Adrian R. Groves
