摘要:The present invention discloses a speech enhancing method, a speech
enhancing device and a denoising communication headphone. In the solutions of thepresent invention, a first sound signal that comprises a user's speech signal transmittedthrough coupling vibration and an ambient noise signal transmitted through the air and asecond sound signal that is mainly an ambient noise signal transmitted through the airare picked up by a primary vibration microphone and a secondary vibration microphone,respectively, that have a specific relative positional relationship therebetween, and theambient noise signals picked up by the two vibration microphones are correlated witheach other; a control parameter used to control an updating speed of an adaptive filter isdetermined according to the first sound signal and the second sound signal; the firstsound signal is denoised and filtered according to the second sound signal and thecontrol parameter; and the denoised and filtered speech signal is further denoised andspeech high-frequency enhancement is performed thereon. The technical solutions of thepresent invention can effectively improve the signal to noise ratio (SNR) and the quality ofspeech in an environment of highly intense noises.
