NOISE ROBUST SPEECH RECOGNITION MAKES IN-CAR NAVIGATION SAFE AND AFFORDABLE

Most automotive systems incorporate sensors, keypads, and displays, all of which contribute to high cost and installation complexity and compromise safety when the navigator is used while driving. A complete voice activated, voice response navigator has recently been introduced to overcome these disadvantages. This paper describes how robust speech recognition help achieve the goals of low cost and safe usage, addressing the problems of speaker independent speech recognition in the presence of wind, engine, and road noise and the influence of the vehicle acoustics and the placement of the microphones. The solution of the problem of recognizing street names from large lists by a combination of alphabet recognizer and a spelling corrector is described. The resulting navigator is a single-board electronic add-on to the vehicle audio system. The recognition and speaking system runs on a low cost digital signal processor, with a micro controller used for audio system control, spelling correction, and route calculation. The navigator's database and software are stored on a standard audio compact disc.
