Selective enablement of speech recognition grammars 
US 9196252 B2

ABSTRACT

A method for processing speech audio in a network connected client device can include selecting a speech grammar for use in a speech recognition system in the network connected client device; characterizing the selected speech grammar; and, based on the characterization, determining whether to process the speech grammar locally in the network connected client device, or remotely in a speech server in the network. In one aspect of the invention, the selecting step can include establishing a communications session with a speech server; and, querying the speech server for a speech grammar over the established communications session. Additionally, the selecting step can further include registering the speech grammar in the speech recognition system.

Abstract - This software project based paper is for a vision of the
near future in which computer interaction is characterised by
natural face-to-face conversations with lifelike characters that
speak, emote, and gesture. The first step is speech. The dream of
a true virtual reality, a complete human-computer interaction
system will not come true unless we try to give some perception to
machine and make it perceive the outside world as humans
communicate with each other. This software project is under
development for “listening and replying machine (Computer)
through speech”.
The Speech interface is developed to convert speech input into
some parametric form (Speech-to-Text) for further processing
and the results, text output to speech synthesis (Text-to-Speech)
