A voice recognition device and method allows position-stabilized capture
of spoken sounds with great repeatability and accuracy. The voice
recognition device may additionally provide two channels of lip movement
information to supplement the usual audible speech component recognition
system in selecting the proper pairing of data input to text output. The
voice recognition device may provide a further channel of information
about the speech generating motions via an ultrasonic injection of sound
into the vocal cavity and subsequent decoding of the emitted sound after
injection. The ultrasonic injection and decoding may also used to provide
audible clues as to the unvoiced sound formed by speaking when the vocal
cords are not energized. The ensemble of electronic equipment upon the
bail band may be in microcircuit form, including placing the components
on a copper layer polyimide flexible strip.
