Global IP Sound Aims to Eradicate Echo and Background Noise in VoIP

Global IP Sound (GIPS) released a new Voice Quality Enhancement (VQE) module aimed at controlling issues of echo, background noise, and other voice processing concerns in VoIP. The company said its GIPS VQE 1.0 module combines all of its currently offered speech processing components that pertain to echo and noise reduction. The module handles speech quality issues by canceling acoustic echo, distinguishing between speech and background noise, and then canceling or reducing this noise while maintaining a comfortable listening volume for the best sounding conversation possible. VQE 1.0 includes: Acoustic Echo Cancellation (AEC), Acoustic Echo Suppression (AES), Noise Cancellation, Noise Suppression, Voice Activity Detection (VAD), Comfort Noise Generation (CNG), and Automatic Gain Control (AGC).

GIPS VQE 1.0 is compatible with software applications such as soft phones, as well as hardware devices like IP phones, and with some modifications, carrier gateways and IADs. The module complies fully with the G.167 standards for acoustic echo cancellation.
