  • Speech recognition based interactive information retrieval scheme using dialogue control to reduce user stress
    Patent number: 7286988
    Abstract: In the disclosed speech recognition based interactive information retrieval scheme, the recognition target words in the speech recognition database are divided into prioritized recognition target words that constitute a number of data that can be processed by the speech recognition processing in the prescribed processing time and that have relatively higher importance levels based on statistical information, and the other non-prioritized recognition target words. Then, the speech recognition processing for the speech input with respect to the prioritized recognition target words is carried out at higher priority, and a confirmation process is carried out when the recognition result satisfies a prescribed condition for judging that the retrieval key can be determined only by a confirmation process with the user.
    Type: Grant
    Filed: July 15, 2003
    Date of Patent: October 23, 2007
    Assignee: Nippon Telegraph and Telephone Company
    Inventors: Kumiko Ohmori, Masanobu Higashida, Noriko Mizusawa
