Abstract

See full text

Range to a human speaker is determined using a laser-based time of flight (ToF) system, with the range then being used to adjust the gain of a microphone receiving the speaker's voice. If desired, an acoustic-based Direction of Arrival (DoA) system uses acoustic information to determine the direction of incoming sound, such as a person talking, and the direction of the sound is then used to focus the area of laser illumination.
