Abstract:
In combination:(a) first extraoral aerodynamic flow magnitude transducer at a first location in front of the mouth of and at a distance from the speaker and facing said speaker of an input speech utterance for sensing the physical extraoral aerodynamic flow of said input speech utterance, said first extraoral aerodynamic flow magnitude transducer having first electrical output signal consistently representing the magnitude of the local extraoral aerodynamic flow at said first location thereof; and(b) second extraoral aerodynamic flow magnitude transducer at a second location lower than said first location and at a distance from said speaker and facing said speaker for sensing said physical extraoral aerodynamic flow of said input speech utterance, said second extraoral aerodynamic flow magnitude transducer having second electrical output signal consistently representing the magnitude of the local extraoral aerodynamic flow at said second location thereof, whereby speech signal in the form of extraoral aerodynamics including physical extraoral flow directions may be sensed.
