Continuous Speech Recognition Consortium (CSRC) was founded for further enhancement of Japanese Dictation Toolkit that had been developed by the support of a Japanese agency. Overview of its product software is reported in this paper. The open-source LVCSR (large vocabulary continuous speech recognition) engine Julius has been improved both in performance and functionality, and it is also ported to Microsoft Windows in compliance with SAPI (Speech API). The software is now used for not a few languages and plenty of applications. For plug-and-play speech recognition in various applications, we have also compiled a repository of acoustic and language models for Japanese. Especially, the acoustic model set realizes wider coverage of user generations and speech-input environments.
