METHOD FOR MULTI-SENSORY SPEECH ENHANCEMENT ON MOBILE HAND-HELD DEVICE AND MOBILE HAND-HELD DEVICE Russian patent published in 2009 - IPC H04M1/03 H04M1/60 G10L21/02 

FIELD: physics; communications.

SUBSTANCE: invention relates to removal of noise from speech signals received by hand-held mobile devices. The mobile hand-held device with multi-sensory speech enhancement comprises an air conduction microphone which converts acoustic waves to a microphone electrical signal which indicates the speech frame, at least one alternative sensor which uses bone conduction and gives out an electrical signal of the alternative sensor, indicating the said speech frame, and a processor which uses the microphone signal and the signal of the alternative sensor to evaluate value of clear speech for the speech frame. The mobile hand-held device can also include a proximity sensor, separate from the air conduction microphone, which indicates distance from the mobile device to the object, and a unit for evaluating a clear signal which uses the microphone signal, signal of the said alternative sensor and proximity sensor to remove noise from the microphone signal and thereby obtaining an amplified clear speech signal.

EFFECT: removal of noise from speech signals received by hand-held mobile devices and generation of sound, taking into account noise value to provide clear speech.
