| Research Abstract |
Dictation is one of the final goal of speech recognition. In USA and EU,there have been researched in the speech recognition projects supported by the governments, such like ARPA and ESPRIT.To catch up with these projects, we had organized "Large-Vocabulary Continuous Speech Recongnition Database WG". The WG made it possible to collect a large ammount of speech database for the newspaper articles by the collaboration with many industrial research laboratories and universities.
The WG activity has been extended to the IPA project for Japanese dictation software development. This grant-aid for scientific research not only promoted the research activities in the investigater's laboratory, but also helped to organize the IPA nation-wide dictation project. The IPA dictation project shows 92% word accuracy for the 5,000-word newspaper article task. The developed acoustic models, language models and recognition program becomes the Japanese performance targets for speech recognition research and development.
