A recent post with comments on other options in the space: https://news.ycombinator.com/item?id=27235970 https://news.ycombinator.com/item?id=27235970 (comment: https://news.ycombinator.com/item?id=27242148 https://news.ycombinator.com/item?id=27242148) Vosk seems to be where the brains/efforts behind the CMUSphinx project went, but I'm not sure -- it's been a long time (like ~10 years) since I used CMUSphinx but it worked reasonably well without much actual optimization way back when I used it -- it's possible/likely that the project is just mostly done and good at what it does. I think a lot of the team/people in the space have moved on to trying to use machine learning to solve the problem rather than the older model-based approaches.
