Abstract
Systems, methods, and non-transitory computer readable media including instructions for noise suppression are described. A head mountable system for noise suppression includes a wearable housing; a coherent light source configured to project light towards a facial region of the head; a detector configured to receive coherent light reflections from the facial region associated with facial skin micromovements and to output associated reflection signals; and a processor configured to: analyze the reflection signals to determine speech timing; receive audio signals from at least one microphone; correlate the reflection signals with the received audio signals to determine portions of the audio signals associated with the words spoken by the wearer; and output the determined portions of the audio signals associated with words spoken by the wearer, while omitting output of other portions of the audio signals not containing the words spoken by the wearer.
