Abstract :
This correspondence reports results for a tracking, real-time microphone array as an input to a hidden Markov model based (HMM-based) connected alpha-digits speech recognizer. For a talker in the near field of the array (within 0.5 m), performance approaches that of a close-talking microphone input device
