speech recognition software for Polish language
Software for speech recognition in Polish language. Large vocabulary continuous speech recognition (LVCSR) and Commands. SkryBot recognises speech in Polish language and changes it into text by using: 1.microphone, 2.sound files (turned off in demo version). SkryBot recognises dictated speech and converts it into text. This means, that if you speak to the microphone or you use earlier recorded sound file, SkryBot will change it into text. SkryBot offers you: 1. audio conversion and cutting sound files into smaller ones, 2. searching for words or phrases in sound files (recognised by SkryBot), 3. editing sound files and automatic cutting off long silence parts in the recording, 4. improving accuracy of recognition. Versions of SkryBot: 1. SkryBot Prawo - for courts, lawyers, police, 2. SkryBot Administracyjny - for civil and government administration, 3. SkryBot Medycyna Rodzinna - for doctors, hospitals. https://sourceforge.net/p/skrybotdomowy/wiki/Home

Note that the whole history including ancient CVS, then some time in monotone, then subversion was united into one GIT repository thanks to ESR's reposurgeon. 2013-05-29: Maintainers of github fork "pyst2" contacted to join forces. Note that the last release here fixes the same bug as on github, otherwise github version seems to only contain cosmetic changes and examples. 2012-07-06: An offer to maintain the project has been received. 2012-01-29: There have been two or three forks that are being maintained. This is now just history unless someone cares to take up maintenance here.
