| Abstract: | In this paper, as a key technology for the improvement of a speech recognition system in car environments, we propose a single-microphone-based acoustic echo canceller that selects an optimum cancellation result based on the echo estimation with maximum likelihood using an acoustic model for signals from multi-loudspeakers. The results of experiments conducted on speech superimposed on music show that the proposed canceller can improve the S/N ratio and speech recognition rate, compared to the canceller based on a NLMS algorithm, where the signals from multi-loudspeakers are measured by a single microphone. |
