Abstract
The invention comprises a lip reading device having a capacitive array for enhanced portable speech recognition.The capacitive array of the invention produces a sequence of signal frames or signal data sets (i.e., digitized output) representative of the proximity and motion of a user's lips at a predetermined sample rate and resolution.The sequence of signal data sets is stored in a first electronic memory and are compared against a reference data set representative of a predetermined acoustic signal stored in a second electronic memory.The attributes of signal data set are compared against the reference data set for likely data matches based on predetermined criteria.
