23. An apparatus comprising:
-
a motion sensor to detect a movement of a user'"'"'s head;
a headset to support the motion sensor at a position substantially constant relative to the user'"'"'s head; and
a data processor to generate a signal indicating a type of movement of the user'"'"'s head based on signals from the motion sensor, the type of movement being selected from a set of pre-defined types of movements. - View Dependent Claims (24, 25, 26, 27)

28. An apparatus comprising:
-
an image capture device to capture images of lips of a user;
a motion sensor to detect a movement of a head of the user and generate a head action signal;
a processor to process the images of the lips and the head action signal to generate lip position parameters and head action parameters;
a headset to support the image capture device and the motion sensor at positions substantially constant relative to the user'"'"'s head as the user'"'"'s head moves; and
a transmitter to transmit the lip position and head action parameters. - View Dependent Claims (29, 30)

39. A method comprising:
obtaining successive images of a speech articulation portion of a face of a user from a position that is substantially constant relative to the user'"'"'s face as a head of the user moves. - View Dependent Claims (40, 41)
-
42. A method comprising:
-
measuring movement of a user'"'"'s head to generate a head motion signal;
detecting a voice of the user; and
recognizing speech based on the voice and the head motion signal. - View Dependent Claims (43, 44, 45, 46)
