Abstract
A global speech user interface (GSUI) comprises an input system to receive a user's spoken command, a feedback system along with a set of feedback overlays to give the user information on the progress of his spoken requests, a set of visual cues on the television screen to help the user understand what he can say, a help system, and a model for navigation among applications. The interface is extensible to make it easy to add new applications.
Claims24
A computer readable storage medium encoded with instructions, which when loaded into a communications system establishes a global speech user interface (GSUI), said GSUI comprising:
- means for performing speech recognition to transcribe spoken commands into commands acceptable by said communications system;
- means for using the transcribed spoken commands to navigate among applications hosted on said communications system;
- and
- means for displaying a set of visual cues to guide a user in issuing proper spoken commands, said visual cues comprising:
- a set of immediate speech feedback overlays, each of which provides non-textual feedback information about a state of said communications system;
- a set of help overlays, each of which provides a context-sensitive list of frequently used speech-activated commands for each screen of every speech-activated application;
- a set of feedback overlays, each of which provides information about a problem that said communications system is experiencing;
- and
- a main menu overlay that shows a list of services available to the user, each of said services being accessible by spoken command.
A method of providing a global speech user interface, comprising operations of:
- performing speech recognition to transcribe spoken input into commands satisfying predetermined criteria;
- using the transcribed spoken commands to navigate among predetermined applications;
- displaying a set of visual cues to guide a user in issuing proper spoken commands, said visual cues comprising:
- a set of immediate speech feedback overlays, each of which provides non-textual feedback information about a state of said global speech user interface;
- a set of help overlays, each of which provides a context-sensitive list of frequently used speech-activated commands for screens of speech-activated ones of the predetermined applications;
- a set of feedback overlays, each of which provides information about a problem that said global speech user interface is experiencing;
- and
- a main menu overlay that shows a list of services available to the user, each of said services being accessible by spoken command.
A global speech user interface system, comprising:
- a speech recognition system transcribing spoken input into machine-recognizable commands;
- a navigation system using the transcribed spoken commands to navigate among predetermined applications;
- an overlay system programmed to display a set of visual cues to guide a user in issuing proper spoken commands, said visual cues comprising:
- a set of immediate speech feedback overlays, each of which provides non-textual feedback information about a state of said global speech user interface system;
- a set of help overlays, each of which provides a context-sensitive list of frequently used speech-activated commands for screens of speech-activated ones of the predetermined applications;
- a set of feedback overlays, each of which provides information about a problem that said global speech user interface system is experiencing;
- and
- a main menu overlay that shows a list of services available to the user, each of said services being accessible by spoken command.
