3. The device of claim 2 , wherein the plurality of acoustical property sets comprises two or more of: a first acoustical property set regarding gender; a second acoustical property set regarding age; a third acoustical property set regarding voiced or unvoiced; a fourth acoustical property set regarding a type of sound; a fifth acoustical property set regarding nationality; and a sixth acoustical property set regarding dialect.
2. The device of claim 1 further comprises the processing module generating the speech characteristic probabilities by: for a frame of the plurality of frames: individually correlating a digital signal component of the frame with at least some of a plurality of acoustical property sets to produce a set of acoustical property correlations; interpreting the set of acoustical property correlations to produce an index; addressing a speech characteristic codebook based on the index to retrieve a speech characteristic sample; and correlating the digital signal component with the speech characteristic sample to produce the speech characteristic probability for the frame.
