Method for activating context sensitive speech recognition in a terminal
First Claim
Patent Images
1. A method for activating speech recognition in a terminal, comprising the steps of:
- (a) detecting an event at the terminal;
(b) performing a first command in response to the event of step (a);
(c) automatically activating speech recognition at the terminal in response to said step (a);
(d) determining whether a second command is received via one of speech recognition and the primary input during a speech recognition time period commenced upon a completion of said step (b);
(e) deactivating speech recognition at the terminal and determining whether the second command is received via the primary input if it is determined that the second command is not received in said step (d) during the speech recognition time period; and
(f) performing the second command received in one of said steps (d) and (e).

Abstract
A process for activating speech recognition in a terminal includes automatically activating speech recognition when the terminal is used and turning the speech recognition off after a time period has elapsed after activation. The process also takes the context of the terminal into account when the terminal is activated and defines a subset of allowable voice commands which correspond to the current context of the device.

27. A terminal capable of speech recognition, comprising:
-
a central processing unit;
a memory unit connected to said central processing unit;
a primary input connected to said central processing unit for receiving inputted commands;
a secondary input connected to said central processing unit for receiving audible commands;
a speech recognition algorithm connected to said central processing unit for executing speech recognition; and
a primary control circuit connected to said central processing unit for processing said inputted and audible commands and activating speech recognition in response to an event for a speech recognition time period and deactivating speech recognition after the speech recognition time period has elapsed.

40. A system for activating speech recognition in a terminal, comprising:
-
a central processing unit;
a memory unit connected to said processing unit;
a primary input connected to said central processing unit for receiving inputted commands;
a secondary input connected to said central processing unit for receiving audible commands;
a speech recognition algorithm connected to said central processing unit for executing speech recognition; and
software means operative on the processor for maintaining in said memory unit a database identifying at least one context related word set, scanning for an event at the terminal, performing a first command in response to the event, activating speech recognition by executing said speech recognition algorithm for a speech recognition time period in response to detecting said event at said terminal, deactivating speech recognition after the speech recognition time period has elapsed, and performing a second command received during said speech recognition time. - View Dependent Claims (41, 42, 43, 44, 45, 46)
