After my grandmother’s continual complaints about her Hearing Aid, I attempted to build my own intelligent version that better cleans speech.
I utilized a variation of Google’s Wavenet in addition to hardware beamforming on Raspberry Pi to separate speech from babble and machine noise, thereby improving hearing aid technology.
