My application is to give audio input while driving bike and detect human voice. For that wind noise remove and voice detection is essential. I have tesetd ADAU1761 codec for my application. But when I tried algorithm of Voice Activity detection and VAD flag, I found that ADAU1761 do not differentiate human voice and other noise like music or whistle. I have also attached project file. I want to know using ADAU 1761 codec, can we precisely detect human speech?
