Performance of an HMM speech recognizer using a real-time tracking microphone array as input
Thomas B. Hughes, Hong Seok Kim, J.H. DiBiase, H.F. Silverman · IEEE Transactions on Speech and Audio Processing · 1999
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.
