Zusammenfassung:A system for, and method of, generating an acoustic model and a mobile communication device that includes an acoustic model having at least one mixture weight vector generated by the method. In one embodiment, the method includes: ( 1 ) generating at least one mixture weight vector, ( 2 ) re-ordering elements of the at least one mixture weight vector to yield at least one re-ordered mixture weight vector and ( 3 ) vector quantizing the at least one re-ordered mixture weight vector to yield at least one quantized re-ordered mixture weight vector.
