SO7: Tools For Spoken LRs


Continuous Speech Recognition Consortium (CSRC) was founded on 2000 to promote sharable high-quality platform for research and development of speech recognition. It is a continued work of the former Japanese Dictation Toolkit project from 1997 to 2000. An overview of the software developed in the first year (Oct. 2000 - Sep. 2001) is given in this paper. We have revised the LVCSR (large vocabulary continuous speech recognition) engine Julius, and constructed new acoustic models using very large speech corpora. Moreover, a variety of acoustic and language models as well as tools are being set up. Currently over 50 companies and academic institutes are joining. The software is available by contacting the address csrc@astem.or.jp.
