Method for speech-based data retrieval on portable devices
First Claim
1. A method of speech-based data retrieval from a portable communication device having access to a dataset that has been semantically indexed for a topical domain, comprising the steps of:
- a) converting one or more spoken keywords related to the topical domain into a query word signal;
b) linking the query word signal to one or more related index words stored in the semantically indexed dataset;
c) retrieving a data file stored in the semantically indexed dataset that is associated with the one or more linked index words; and
d) processing the retrieved data file for presentation.

Abstract
Methods and apparatus are provided for speech-based data retrieval from a portable communication device, such as a cell phone with an onboard dataset. The method comprises semantically indexing the dataset with domain related keywords that are intuitive to a user familiar with the dataset domain. When the user speaks a keyword, a speech recognition system within the portable device links the keyword to a semantically related data file in the dataset. A processor in the portable communication device retrieves the selected data and converts it for presentation on a visual display and/or an audio output.
