Abstract

A system for operating one or more devices using speech input including a receiver for receiving a speech input, a controller in communication with said receiver, software executing on said controller for converting the speech input into computer-readable data, software executing on said controller for generating a table of active commands, the table including a portion of all valid commands of the system, software executing on said controller for identifying at least one active command represented by the data, and software executing on said controller for transmitting the active command to at least one device operable by the active command.

Claims (29)

1. A system for operating one or more devices using speech input, comprising:
a receiver for receiving a speech input;
a controller in communication with said receiver;
software executing on said controller for converting the speech input into com-puter-readable data;

a command menu including a plurality of command menu levels;
software executing on said controller for identifying at least two commands in sequence represented by the data, each of the at least two commands from a different command menu level; and software executing on said controller for sending the at least two commands to one or more devices operable by the system.
2. The system according to claim 1, further comprising:
software executing on said controller for identifying an isolated command repre-sented by the data; and software executing on said controller for implementing the isolated command.
3. The system according to claim 1, wherein said command menu includes one or more global commands.
4. The system according to claim 3, further comprising:
software executing on said controller for identifying a global command repre-sented by the data; and software executing on said controller for implementing the global command.
5. The system according to claim 1, wherein the one or more devices operable by the system are medical devices.
6. A system for operating one or more devices using speech input, comprising:
a receiver for receiving a speech input;
a controller in communication with said receiver;
software executing on said controller for converting the speech input into com-puter-readable data;

software executing on said controller for generating a table of active commands, the table including active commands selected from at least two different levels of a command menu;
software executing on said controller for identifying at least one active command represented by the data; and software executing on said controller for sending the at least one active com-mand to one or more devices operable by the system.
7. The system according to claim 6, wherein the at least one active command is an isolated command.
8. The system according to claim 6, wherein said software for identifying at least one active command identifies at least one other active command in sequence.
9. The system according to claim 8, wherein each of the at least one active com-mand and at least one other active command are sequential commands each from a different level of the command menu.
10. The system according to claim 6, wherein the table of active commands includes at least one global command.
11. The system according to claim 10, further comprising:
software executing on said controller for identifying a global command repre-sented by the data; and software executing on said controller for implementing the global command.
12. The system according to claim 6, wherein the one or more devices operable by the system are medical devices.
13. The system according to claim 6, wherein the speech input includes isolated speech.
14. The system according to claim 6, wherein the speech input includes continuous speech.
15. The system according to claim 6, wherein the speech input includes isolated speech and continuous speech.
16. The system according to claim 6, wherein the table of active commands includes at least one isolated command phrase and at least one concatenated command phrase.
17. The system according to claim 6, wherein the active commands are selected from the command menu based on a depth parameter.
18. The system according to claim 17, wherein the depth parameter is indicative of a deviation from a current menu position.
19. The system according to claim 18, wherein the depth parameter is indicative of a number of menu levels.
20. The system according to claim 6, wherein said software for identifying at least one active command parses the data into one or more potential commands.
21. The system according to claim 6, wherein said software for identifying at least one active command queries the table of active commands.
22. The system according to claim 6, wherein said software for identifying at least one active command queries a table of command equivalents.
23. A method of controlling a device using a speech input, comprising the steps of:
determining commands associated with each device of a system from a com-mand menu;
generating a table of active commands, wherein the table includes active com-mands selected from at least two different levels of the command menu;
receiving a speech input;
converting the speech input into computer-readable data;
identifying at least one active command represented by the data; and sending the active command to at least one device to which the active command pertains.
24. The method according to claim 23, wherein the step of generating the table of active commands includes determining the last active command identified.
25. The method according to claim 23, wherein the step of generating the table of active commands includes utilizing a depth parameter, the depth indicative of a number of menu levels.
26. The method according to claim 23, wherein the step of identifying at least one active command includes parsing the data into one or more potential commands.
27. The method according to claim 23, further comprising the step of:
displaying the identified at least one active command.
28. The method according to claim 23, wherein the step of identifying the at least one active command includes generating a prompt to a user of the system.
29. The method according to claim 23, wherein the table of active commands in-cludes at least one isolated command and at least one command sequence.
