Abstract :
The voice extraction (VE) system described in this paper is an enabling technology that provides pure voice signals to speech processing systems in noisy vehicle environments. The technology is used to extract a single voice signal of interest from a mixture of sounds, including background noise, music, and multiple speakers. The technology embodies both hardware and software elements. Tests conducted inside a noisy vehicle are presented
