Abstract
The present invention allows telephony users and on line users to communicate with one another using an instant massaging (AIM) service. The on line IM user will provide and receive textual messages, wherein the telephony user will provide and receive corresponding audible messages. To allow more efficient interaction with the telephony user, responses to queries posed to the telephony user are structured with possible answers. The answers are used to define and limit the voice recognition grammar for processing the telephony user's response. Predefining the grammar for responses increases the effectiveness of the speech recognition system and the integrity of the IM session. Further, voice commands may be predefined to facilitate better control of the IM session as well as provide more effective communications.
