| Abstract(in English) | In this paper, aiming to a real use of speech recognition for car navigation systems, we analyze and evaluate in-car speech collected in running cars using 7 (seven) array microphones and one head-set microphone. We evaluate in-car speech from the viewpoints of ASR accuracy using a noise reduction method integrating the summation of array microphones and Spectral Subtraction (SS) to obtain ASR accuracy improvement. |
