VC-to-DTMF interfacing system and method
First Claim
Patent Images
1. A voice command (VC) to dual tone multi-frequency (DTMF) interfacing system comprising:
- a first echo canceller for echo canceling a received voice command from a caller in a first mode;
a translator for translating the echo cancelled voice command into a DTMF code for use by a DTMF-driven system;
a second echo canceller for echo canceling audio output sent to the caller from the DTMF-driven system;
a first port for receiving a call from the caller;
a second port for sending the DTMF code to and receiving the audio output from the DTMF-driven system;
a port patch for connecting audio from the first port directly to the second port in a second mode; and
a tone detector for detecting a tone, in the first mode, from the DTMF-driven system to switch to the second mode.

Abstract
A voice command (VC)-to-DTMF interfacing system that allows existing DTMF-driven systems to be interacted with by a caller using voice commands. The VC-to-DTMF interfacing system translates the voice command from a caller into the DTMF codes which are then played through a port for receipt by the DTMF-driven system. In a first mode, the voice commands from the caller and the pre-recorded messages of the DTMF-driven system are echo cancelled. In a second mode, a voice message is directly streamed to the DTMF-driven system through an enabled port patch.

7. A method of interacting with a dual tone multi-frequency (DTMF) driven system with voice commands comprising steps of:
-
echo canceling a received voice command from a caller in a first mode; translating the echo cancelled voice command into a DTMF code for use by the DTMF-driven system; echo canceling audio output sent to the caller from the DTMF-driven system; receiving a call from the caller at a first port; sending the DTMF code to and receiving the audio output from the DTMF-driven system at a second port; enabling a port patch for connecting audio from the first port directly to the second port in a second mode; detecting a tone from the DTMF-driven system, in the first mode, to switch to the second mode; and enabling the port patch, in response to the detecting step. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of interacting with a dual tone multi-frequency (DTMF) driven system with voice commands, the method comprising steps of:
-
receiving at a first port audio input from a user, the audio input comprising the voice commands; translating the voice commands into corresponding DTMF codes for use by the DTMF driven system; in response to the step of receiving, connecting to the DTMF driven system through a second port to receive audio output of the DTMF driven system and send the corresponding DTMF codes to the DTMF driven system; sending the audio output of the DTMF driven system to the user through the first port; detecting a tone from the DTMF driven system, the tone signaling the user to record a message; in response to detection of the tone, enabling a port patch for connecting audio input of the user from the first port directly to the second port.
