Abstract

The present invention relates to a system for retrieving information from a network such as the Internet. A user creates a user-defined record in a database that identifies an information source, such as a web site, containing information of interest to the user. This record identifies the location of the information source and also contains a recognition grammar based upon a speech command assigned by the user. Upon receiving the speech command from the user that is described within the recognition grammar, a network interface system accesses the information source and retrieves the information requested by the user.

Claims

1. A method for retrieving information by a voice-browsing system, from an information source over a network, said method comprising steps of:

receiving a speech command from a user provided via an electronic communication device, by a speech-recognition engine coupled to a media server, the media server configured to identify and access the information source via the network, the speech-recognition engine adapted to select speech-recognition grammar established to correspond to the speech commands received from the user and assigned to a desired search;

selecting, by the media server, at least one appropriate information source retrieval instruction corresponding to the speech-recognition grammar established for a particular speech command, the at least one appropriate information-source-retrieval instruction stored in a database associated with the media server and adapted to retrieve information;

accessing, by a web browsing server, a portion of the information source to retrieve information of interest requested by the user, by selecting the information of interest from the information source and retrieving only the portion of the information according to the at least one appropriate information source retrieval instruction described, the information source periodically updated with current information;

converting the information retrieved from the information source into an audio message by a speech-synthesis engine, the speech-synthesis engine coupled to the media server; and

transmitting the audio message to the electronic-communication device for a particular user requesting information of interest to the user.
