Abstract: A method and apparatus determine a likelihood of a speech state based on an alternative sensor signal and an air conduction microphone signal. The likelihood of the speech state is used, together with the alternative sensor signal and the air conduction microphone signal, to estimate a clean speech value for a clean speech signal.

Abstract: A method and apparatus determine a likelihood of a speech state based on an alternative sensor signal (316) and an air conduction microphone signal (318). The likelihood of the speech state is used, together with the alternative sensor signal and the air conduction microphone signal, to estimate (322) a clean speech value for a clean speech signal (324).
