Toronto, Canada - GAO Research Inc. (www.GAOResearch.com) has released its updated Voice Activity Detector (VAD) and Comfort Noise Generator (CNG)software. These modules are used to enable the reduction of transmission rate during silent periods of speech. The Voice Activity Detection (VAD) and Comfort Noise Generator (CNG) algorithms allow the insertion of an artificial noise during silent intervals of speech. This feature avoids noise modulation that would otherwise be present.If thebackground acoustic noise that is present during active periods of speech abruptly disappears, noise modulation may reduce the intelligibility of the speech. The function of the Voice Activity Detector is to reliably detect the presence or absence of speech and to convey this information to the CNG algorithm. The Comfort Noise Generator is responsible for generating noise that matches the actual background noise while keeping the global transmission cost as low as possible.
