Abstract

An arrangement for allowing “hands-free” access to DTMF-controlled systems, such as one's voice mail messaging systems, utilizes a speech-to-DTMF tone application that monitors the communication between the user and the DTMF-controlled system. A speech recognition unit is utilized to retrieve certain voice commands (e.g., “next”, “skip”, “repeat”, “forward”, etc.) when uttered by the user. The application then translates the received commands into the proper DTMF tone sequence used by the DTMF-controlled system and transmits the DTMF tones to the system. The application is particularly useful in the cell phone environment and avoids the necessity of the user to constantly switch between using the keypad and listening to messages/commands from the system.

First claim

What is claimed is:

1. A method comprising:
receiving a spoken voice command from a user;
when the spoken voice command corresponds to a user customized command in a user record:
translating the spoken voice command into a digital command based on the user record; and
interacting with a remote application via the digital command;

when the spoken voice command does not correspond to the user customized command in the user record and the spoken voice command is understood:
translating the spoken voice command into the digital command based on a conventional command; and
interacting with the remote application via the digital command; and

when the spoken voice command is not understood, providing an error message to the user.

2. The method of claim 1 , further comprising bridging together a first call between the user and the remote application and a second call between a command translation application and the remote application.

3. The method of claim 2 , further comprising transmitting the digital command to the command translation application.

4. The method of claim 1 , further comprising requesting the user to input spoken user identifying information.

5. The method of claim 4 , further comprising:
receiving the spoken user identifying information;
validating the spoken user identifying information; and
permitting the user to access the remote application upon successfully validating the spoken user identifying information.

6. The method of claim 1 , wherein the digital command comprises dial-out information associated with the remote application.

7. The method of claim 1 , wherein the receiving of the spoken voice command, the translating of the spoken voice command, and the interacting with the remote application occur as the user is engaged in a conversation with a second user.

8. The method of claim 7 , wherein the conversation is a telephone conversation.

9. A system comprising:
a processor; and
a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising:
receiving a spoken voice command from a user;
when the spoken voice command corresponds to a user customized command in a user record:
translating the spoken voice command into a digital command based on the user record; and
interacting with a remote application via the digital command;

when the spoken voice command does not correspond to the user customized command in the user record and the spoken voice command is understood:
translating the spoken voice command into the digital command based on a conventional command; and
interacting with the remote application via the digital command; and

when the spoken voice command is not understood, providing an error message to the user.

10. The system of claim 9 , the computer-readable storage medium having additional instructions stored which, when executed by the processor, cause the processor to perform operations comprising bridging together a first call between the user and the remote application and a second call between a command translation application and the remote application.

11. The system of claim 10 , the computer-readable storage medium having additional instructions stored which, when executed by the processor, cause the processor to perform operations comprising transmitting the digital command to the command translation application.

12. The system of claim 9 , the computer-readable storage medium having additional instructions stored which, when executed by the processor, cause the processor to perform operations comprising requesting the user to input spoken user identifying information.

13. The system of claim 12 , the computer-readable storage medium having additional instructions stored which, when executed by the processor, cause the processor to perform operations comprising:
receiving the spoken user identifying information;
validating the spoken user identifying information; and
permitting the user to access the remote application upon successfully validating the spoken user identifying information.

14. The system of claim 9 , wherein the digital command comprises dial-out information associated with the remote application.

15. The system of claim 9 , wherein the receiving of the spoken voice command, the translating of the spoken voice command, and the interacting with the remote application occur as the user is engaged in a conversation with a second user.

16. The system of claim 15 , wherein the conversation is a telephone conversation.

17. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:
receiving a spoken voice command from a user;
when the spoken voice command corresponds to a user customized command in a user record:
translating the spoken voice command into a digital command based on the user record; and
interacting with a remote application via the digital command;

when the spoken voice command does not correspond to the user customized command in the user record and the spoken voice command is understood:
translating the spoken voice command into the digital command based on a conventional command; and
interacting with the remote application via the digital command; and

when the spoken voice command is not understood, providing an error message to the user.

18. The computer-readable storage device of claim 17 , having additional instructions stored which, when executed by the computing device, cause the computing device to perform operations comprising bridging together a first call between the user and the remote application and a second call between a command translation application and the remote application.

19. The computer-readable storage device of claim 18 , having additional instructions stored which, when executed by the computing device, cause the computing device to perform operations comprising transmitting the digital command to the command translation application.

20. The computer-readable storage device of claim 17 , having additional instructions stored which, when executed by the computing device, cause the computing device to perform operations comprising requesting the user to input spoken user identifying information.
