Abstract

A system and method for switching between the command-mode of operation and the text-mode of operation in voice-recognition systems. The system operates using voice-recognition software and a mechanical switch which together enable the system to differentiate between spoken commands that are used to operate the system and spoken words that are inserted as text into a software application. The mechanical switch can be added to a conventional computer mouse, hand-held or desk-mounted microphone, personal digital assistant such as a Palm Pilot, or any other apparatus either used with or having a microphone. Alternatively, the system and method can be implemented using software alone without a mechanical switch, i.e., an electronic switch, wherein a specialized word or words are used to command the system to switch between the command-mode and the text-mode. Such an electronic switch can be implemented in a mouse, microphone or electronic organizer in addition to or in lieu of any mechanical switch such apparatus may contain.

Claims

1. A method for switching between the command-mode and text-mode of operation in a voice-recognition system, the method comprising:

operating the voice-recognition application in one of a command mode or a text-mode, wherein the command-mode is used to issue commands that are executable on a computer on which the voice-recognition system resides, and wherein the text-mode is used to insert text into a software application that is in use using the voice-recognition system;

detecting a change in a switching device; and

in response to detecting the change, operating the voice recognition application in the other of the command mode or the text mode; and

wherein, after detecting the voice-recognition application as being in the command mode the method further comprises;

recognizing one or more voice inputs entered by a user as one or more command;

sequentially operating one or more of (i) multiple computers, (ii) multiple appliances, (iii) multiple devices, or (iv) multiple applications using the one or more commands.

2. An apparatus for switching between the command-mode and text-mode of operation in voice-recognition systems, wherein the apparatus is provided with a computer on which a voice-recognition system executes, and wherein the apparatus comprises:

a switch having at least two positions, including a first position for using the voice-recognition system in a command-mode of operation and a second position for using the voice-recognition system in a text-mode of operation, wherein the voice-recognition application in the command-mode is used to sequentially issue commands, from the computer on which the voice-recognition system executes, to any one of two or more (i) computers, (ii) appliances, (iii) devices, or (iv) applications operated on the computer, and wherein the voice-recognition system in the text-mode is used to insert text an application that is in use.

3. The apparatus of claim 2, wherein the apparatus further comprises a microphone that enables the voice-recognition system to receive spoken commands and spoken text, wherein the microphone is configured to be switched on only when the switch is positioned for the voice-recognition system to be in either in the command-node or the text mode.

4. The apparatus of claim 2, wherein the switch is a mechanical switch moveable between the first position and the second position.

5. The apparatus of claim 4, wherein the switch is a spring-controlled slide switch.

6. The apparatus of claim 5, wherein the spring-controlled slide switch has a first operating position at which the microphone is turned off, a second operating position at which the microphone is turned on in the command-mode, and a third operating position at which the microphone is turned on in the text-mode.

7. The apparatus of claim 6, wherein the first position is a default position such that when a user slides the switch from the first position to the second position and then releases the switch, the switch returns to the first position, and when the user slides the switch from the first position to the third position and then releases the switch, the switch returns to the first position.

8. The apparatus of claim 2, further comprising at least one button that is moveable between the first position and the second position in order to switch between the command-mode and the text-mode.

9. The apparatus of claim 2, wherein the apparatus further comprises a computer mouse for enabling a user to operate the switch.

10. The apparatus of claim 2, wherein the apparatus further comprises a microphone on which the switch is provided.

11. The apparatus of claim 2, wherein the apparatus combines the functionality of both a microphone and a mouse/cursor control device in enabling the user to use the voice-recognition system and to operate the switch.

12. The apparatus of claim 2, wherein the apparatus further comprises a wireless device for enabling the user to operate the switch.

13. The apparatus of claim 2, wherein the apparatus comprises a cable for enabling the user to operate the switch.

14. The apparatus of claim 2, wherein a portion of the apparatus operates using an infrared frequency that indicates whether the switch has moved between the first position and the second position.

15. The apparatus of claim 2, wherein a portion of the apparatus operates at a radio frequency.

16. A system for switching between the command-mode and text-mode of operation in voice-recognition systems, wherein the system is provided on a computer having a microphone coupled to it to receive voice input from a user, wherein the system comprises:

a voice-recognition software executable on the computer system, wherein the voice-recognition software is configured to enable the user to switch between a command-mode of operation and a text-mode of operation, wherein the voice-recognition software is operable in the command-mode to process voice input as commands and to sequentially issue commands interpreted from the voice inputs, from the computer on which the voice-recognition system executes, to any one of two or more (i) computers, (ii) appliances, (iii) devices, or (iv) applications residing on that computer, and wherein the voice-recognition software is operable in the text-mode to process voice input as text for a software application; and

wherein the voice-recognition software includes a software-executable switch that is manually operable by the user to switch the voice-recognition software between the command-mode and the text-mode.

17. The system according to claim 16, wherein when the voice-recognition software (i) is in the command-mode and (ii) is unable to understand a spoken command, the voice-recognition software prompts the user to select an intended command from a plurality of commands, and wherein the voice-recognition software displays at least some of the plurality of commands to aid the user in selecting the intended command.

18. The system according to claim 16, wherein voice-recognition software is configured to detect the user speaking the intended command in response to the intended command being displayed as one of the plurality of commands that are displayed.
