Abstract: A system for tuning the text-to-speech conversion process having a text-to-speech engine that converts the input text into a processed text form which includes speech features. A visual editing interface displaying the processed text form using graphical indicators on an output device to allow a user to edit the text and graphical indicators to modify the speech features of the text input.

Abstract: A voice-tag editor develops voice-tag “sounds like” pairs for a voice-tagging lexicon. The voice-tag editor is receptive of alphanumeric characters input by a user. The alphanumeric characters are indicative of a voice tag and/or “sounds like” text. The voice-tag editor is configured to allow the user to view and edit the alphanumeric characters. A text parser connected to the voice-tag editor generates normalized text corresponding to the “sounds like” text. The normalized text serves as recognition text for the voice tag and is displayed by the voice-tag editor. A storage mechanism is connected to the editor. The storage mechanism updates the lexicon with the alphanumeric characters which represent voice-tag “sounds like” pairs.

Abstract: Personalized agent services are provided in a personal messaging device, such as a cellular telephone or personal digital assistant, through services of a speech recognizer that converts speech into text and a text-to-speech synthesizer that converts text to speech. Both recognizer and synthesizer may be server-based or locally deployed within the device. The user dictates an e-mail message which is converted to text and stored. The stored text is sent back to the user as text or as synthesized speech, to allow the user to edit the message and correct transcription errors before sending as e-mail. The system includes a summarization module that prepares short summaries of incoming e-mail and voice mail. The user may access these summaries, and retrieve and organize email and voice mail using speech commands.

Abstract: A hash function based data retrieval system for use with a lexicon database of a data processing system is disclosed. The system comprises a RAM, a disk memory, and a data file residing in the disk memory, wherein the data file contains stored data and is organized into nests. The system further comprises a hashing data structure residing in RAM, wherein the data structure is designed to occupy a fixed amount of memory independent of content of the data file. A data retrieval module is operable to identify a nest using a hash function that is based on parameters selected according to characteristics of the data file. The hash function is further designed to be optimized for content of the data file. The hash function is further designed to produce hash values based on the fixed amount of memory.

Abstract: An automated form filling system includes an input receptive of a plurality of information inputs from a plurality of information sources. An information fuser is operable to select information from the plurality of information inputs based on a comparison of the information inputs, and based on knowledge relating to reliability of the information sources. A form filler is operable to fill an electronic form with the selected information.
