Voice-operated interface for DTMF-controlled systems
View Patent ↗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.
1. A voice-operated arrangement for interacting with a plurality of dual-tone multi-frequency (DTMF)-controlled systems associated with a user, the arrangement comprising:
a speech recognition unit that generates a digital signal representative of a particular received voice command from the user; and
a speech-to-DTMF tones application that responds to the digital signal, accesses a user record from a plurality of records, retrieves dial-out information for one of the plurality of DTMF-controlled systems and completes a communication path between the user and the one DTMF-controlled system, wherein:
the voice-operated arrangement monitors the communication path, retrieves further voice commands uttered by the user and translates the further voice commands into DTMF tones which are thereafter transmitted to the one DTMF-controlled system;
the user record comprises a plurality of different fields comprises a series of said DTMF tones for accessing the one DTMF-controlled system within the plurality of DTMF-controlled systems.
