A mobile device is provided that includes a digit input that can be manipulated by a user's fingers or thumb, an air conduction microphone and an alternative sensor that provides an alternative sensor signal indicative of speech. Under some embodiments, the mobile device also includes a proximity sensor that provides a proximity signal indicative of the distance from the mobile device to an object. Under some embodiments, the signal from the air conduction microphone, the alternative sensor signal, and the proximity signal are used to form an estimate of a clean speech value. In further embodiments, a sound is produced through a speaker in the mobile device based on the amount of noise in the clean speech value. In other embodiments, the sound produced through the speaker is based on the proximity sensor signal.

The invention relates to a butterfly temporal bone conductive communication and / or hear-assisting device which is provided with a system device, a bone skin conduction and oscillation device and a vehicle device loading the system device and the bone skin conduction and oscillation device; wherein the vehicle device is provided with a structural body which can closely contact the bone skin conduction and oscillation device and the butterfly temporal bone at the butterfly temporal bone part; in addition, the bone skin conduction and oscillation device comprises a energy converter for converting electric signals and sound oscillation waves, which can transmit sound oscillation waves to inner ear through the butterfly temporal bone by means of bone conduction and receive the oscillation waves generated by a sounding vibrating skull and convert the oscillation waves into electric signals; on the basis, since bone conductive communication of sound oscillation waves can be carried out at the butterfly temporal bone part, according to applications, the vehicle device can be used as a bone conduction loudspeaker, a bone conduction microphone, a bone conduction multi-media device or a bone conduction communication device; if a peripheral external audio acquisition device is added, the vehicle device can be used as a bone conduction hear-assisting device or a bone conduction communication hear-assisting device; if a nose bone conduction device is added, the vehicle device can be used as a nose butterfly temporal bone conduction communication or communication hear-assisting device for reducing external noise of an air conduction mode and conveniences brought about by structural sliding in frequently-used bone skin conduction mode or by additional installation of construction members.

A method and system use an alternative sensor signal received from a sensor other than an air conduction microphone to estimate a clean speech value. The estimation uses either the alternative sensor signal alone, or in conjunction with the air conduction microphone signal. The clean speech value is estimated without using a model trained from noisy training data collected from an air conduction microphone. Under one embodiment, correction vectors are added to a vector formed from the alternative sensor signal in order to form a filter, which is applied to the air conductive microphone signal to produce the clean speech estimate. In other embodiments, the pitch of a speech signal is determined from the alternative sensor signal and is used to decompose an air conduction microphone signal. The decomposed signal is then used to determine a clean signal estimate.
