1. A method of operating an automatic speech recognition service accessible by a client over a packet network, comprising the steps of:
- a. receiving from the client over the packet network information corresponding to a grammar used for speech recognition, wherein said grammar corresponds to words associated with information to be inserted in a form;
b. receiving from the client over the packet network information representing speech;
c. recognizing the received speech information by applying an automatic speech recognition algorithm in accordance with the grammar; and
d. sending information based upon the recognized speech over the packet network to the client to used be in the form.

Abstract
A system and method of operating an automatic speech recognition service using a client-server architecture is used to make ASR services accessible at a client location remote from the location of the main ASR engine. The present invention utilizes client-server communications over a packet network, such as the Internet, where the ASR server receives a grammar from the client, receives information representing speech from the client, performs speech recognition, and returns information based upon the recognized speech to the client.
