18. The system of claim 15 , wherein when an utterance has been correctly processed, at least one parameter in the ASR grammar is adjusted to increase a likelihood that the ASR system processes phrases in a similar fashion in future ASR operations involving the ASR grammar, and when an utterance has been incorrectly processed, at least one parameter in the ASR grammar is adjusted to decrease a likelihood that the ASR system processes phrases in a similar fashion in future ASR operations involving the ASR grammar.
15. A computer-implemented system for performing speech recognition, the system comprising: at least one computer programmed to: initiate a communication session with a speaker, the communication session requiring automatic speech recognition (ASR); and determine a characteristic of the speaker, the characteristic selected from a group consisting of a speaker identity and at least one voice characteristic for the speaker; and an identification unit configured to identify a speaker-dependent phrase-based ASR grammar to use in the communication session, wherein different phrase-based grammars are used for different users based on at least one speaker-dependent feature independent of a gender of the users; an information collection unit configured to record feedback in real-time of ASR phrase processing operations during the communication session, wherein each ASR phrase processing operation seeks to match a spoken utterance against at least one entry within the identified speaker dependent, phrase-based grammar, each entry of the at least one entry within said identified speaker dependent, phrase-based grammar having a plurality of grammar option weights, each of the plurality of grammar option weights corresponding to a respective speech processing context, wherein the grammar option weights affect which entries are matched to the spoken utterances; and a logic unit configured to utilize said recorded feedback to automatically adjust the grammar option weights of the ASR grammar to improve accuracy of the identified speaker dependent, phrase-based grammar.
