摘要：
This correspondence reports results for a tracking, realtime 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.
