9. A computer-implemented method performed by a computer system for processing an interaction, the interaction including an utterance requiring recognition before being usable for further computer-implemented processing, the computer-implemented method comprising: receiving data representing an utterance from a computer application, the utterance received from a device of a customer over a computer network; identifying a grammar to which the utterance is expected to conform; determining a time length of the utterance; dynamically selecting, based at least in part on the identified grammar and the time length of the utterance, one or more recognizers from: an automated speech recognizer (ASR), and a second type of recognizer, different from the automated speech recognizer, and communicating over a computer network with devices located at locations remote from the computer system; and providing a recognition result responsive to results of processing by the one or more recognizers.

The computer-implemented method of claim 9 , wherein said dynamically selecting favors selection of the automated speech recognizer relative to the second type of recognizer based on recognition cost factors.
