A dialing mode of a telematics unit in a vehicle is controlled by monitoring for dialing digits from a vehicle occupant, determining whether the type of dialing digits are continuous dialing digits or discrete dialing digits, establishing a continuous mode for receiving continuous dialing digits or a discrete mode for receiving discrete dialing digits based on the determination, and if the type of dialing digits changes, switching the established mode.

Method of controlling dialing modes in a vehicle

A method for recognizing speech involves reciting, into a speech recognition system, an utterance including a numeric sequence that contains a digit string including a plurality of tokens and detecting a co-articulation problem related to at least two potentially co-articulated tokens in the digit string. The numeric sequence may be identified using i) a dynamically generated possible numeric sequence that potentially corresponds with the numeric sequence, and/or ii) at least one supplemental acoustic model. Also disclosed herein is a system for accomplishing the same.
