A microphone array for car environments
Yves Grenier · 1992
The authors describe a microphone array for speech recording in car environments. The array is designed for hands-free radiotelephone, and is also used as a front-end for an automatic speech recognition system. The configuration of the array and the adaptive beamforming technique implemented are described and the performance of the array are evaluated. The measure of performance is the score obtained with a speech recognition system. Within the European ESPRIT project ARS (adverse environment recognition of speech), a prototype of this microphone array was built. It has eight microphones and works in real time, using one TMS C30 processor.>
