A Novel Method for Speech Acquisition and Enhancement by 94 GHz Millimeter-Wave Sensor
Sensors, 2015 In order to improve the speech acquisition ability of a non-contact method, a 94 GHz millimeter wave (MMW) radar sensor was employed to detect speech signals. This novel non-contact speech acquisition method was shown to have high directional sensitivity,
