19. The system as defined in claim 18 wherein the computer readable code for identifying the numeric sequence using at least one supplemental acoustic model includes: computer readable code for developing a base acoustic model including a plurality of words or expressions, each assigned with a statistical numeric value; computer readable code for testing the base acoustic model to recognize at least one co-articulation issue with the plurality of words or expressions; and computer readable code for generating the at least one supplemental acoustic model based on results from the testing of the base acoustic model.
18. A system for recognizing speech, comprising: a microphone configured to receive an utterance from a source, the utterance including a numeric sequence having a digit string including a plurality of tokens; and a processor selectively and operatively connected to the microphone, the processor including: computer readable code for detecting a co-articulation problem related to at least two potentially co-articulated tokens in the digit string; and computer readable code for identifying the numeric sequence using one of i) a dynamically generated possible numeric sequence that potentially corresponds with the numeric sequence, or ii) at least one supplemental acoustic model.
