Claim 20:
21. A wearable sensing system for determining speech based on minute facial skin surface movements, the wearable sensing system comprising:
a housing configured to be worn on a head of a user;
at least one coherent light source associated with the housing and configured to direct light towards a facial region of the head;
at least one sensor associated with the housing and configured to receive light source reflections from the facial region and to output associated reflection signals,
wherein the housing is configured such that when worn, the at least one sensor is held at a distance of at least 2 cm from the skin surface; and
at least one processor configured to:
receive the reflection signals from the at least one sensor in a time interval;
analyze the reflection signals to identify minute facial movements in the time interval;
decipher the minute facial movements to determine associated speech; and
generate output of the associated speech.
