Bavieca (www.bavieca.org) Reviews

I started bavieca for about a week and tried to build Indonesian ASR for news reading domain. The results is very good compare to julius and HTK (5K words LM; WER around 2-3%; untrained speaker). Bavieca is a very promising tool.

I started using BAVIECA one month ago with the help of various scripts kindly made available by Daniel Bolanos and I was able to reproduce quite good results on WSJ, almost reproducing Dani's original results. I am now porting BAVIECA to Italian and I just trained an Adult Speech ASR (read speech, APASCI-FBK corpus) and a Child Speech ASR (ChildIt-FBK) both using also some MLLR adaptation iterations. Results are FANTASTIC and essentially better than those previously obtained with similar toolkit (Cslu Toolkit, Sonic, Sphinx and Julius). As a simple example, PHONETIC RECOGNITION ERROR was only 15% with children speech. More results will be reported as soon as I'll develop new things (VTLN, MMI, ecc.) Indeed, BAVIECA was quite useful.
