发明名称 NOISE REDUCTION ON WIRELESS HEADSET INPUT VIA DUAL CHANNEL CALIBRATION WITHIN MOBILE PHONE
摘要 A communication device includes: (1) a wireless adapter at which a wireless headset is communicatively connected to the communication device and at which is received a first acoustic input that includes a speech input and a first ambient noise input; (2) a microphone that receives a second acoustic input, which includes a second ambient noise input; and (3) a dual-channel adaptive noise canceller that utilizes the second ambient noise input to filter the first ambient noise input out of the first acoustic input to generate an acoustic output that primarily comprises the speech input.
