Voice packet data network browsing for mobile terminals system and method using a dual-mode wireless connection
First Claim
1. An interactive voice response (IVR) system, comprising:
- a network;
a server coupled to said network;
a voice application accessible via said server; and
a mobile terminal, wherein a call connection having a data mode and a voice mode is established between said mobile terminal and said server, including;
a transceiver for establishing a wireless link between said mobile terminal and said network, wherein said transceiver is coupled to receive from said voice application a state-dependent grammar using said data mode and state-dependent voice output using said voice mode, an audio input/output (I/O) which outputs said voice output to a user and receives voice input from said user, and a speech processor for extracting valid input from said voice input based on said grammar, wherein said transceiver sends said valid input to said voice application via said data mode.

Abstract
A system and method for voice browsing IVR services using a mobile terminal. A voice application is accessible via a server connected to a network. A call connection is established between the mobile terminal and the server using a dual-mode connection. The call connection includes a voice mode and a data mode for alternately transmitting voice and data via the network. The voice application sends a state-dependent grammar that defines the speech recognition results that the voice application is ready to accept as input or commands at its present state of execution. The voice application also sends to the mobile terminal state-dependent voice output such as audio prompts and instructions using the voice mode. The user responds orally to the voice output. The mobile terminal processes this voice input using speech recognition facilities. Valid input is extracted from the voice input based on the state-dependent grammar. The mobile terminal sends the valid input to the voice application using the data mode. The voice application updates its state of execution based on the valid input.

10. A method for allowing a user to interact with a voice application using a mobile terminal, wherein the voice application is accessible via a server coupled to a network, and wherein the mobile terminal communicates with the network via a wireless link, comprising the steps of:
-
(a) opening a call connection between the mobile terminal and the server, wherein said call connection includes a voice mode and a data mode;
(b) downloading at the mobile terminal a state-dependent grammar and state-dependent voice output, wherein said grammar is sent using said data mode and said voice output is sent using said voice mode;
(c) outputting said voice output to the user;
(d) receiving voice input from the user;
(e) applying said grammar to said voice input, thereby extracting valid input;
(f) uploading said valid input at the server; and
(g) determining a new state based on said valid input.
