Is this project still active?
What I also have been wondering.
We are working on other ASR solutions internally. We haven't yet reached a satisfactory WER and the optimization is still going to be little time-consuming. Based on what gets achieved, we might merge or create a new repository with the improved solution.
is the new solution going to be open source?
At the moment we have no timeline for it. As the solution is still in its infancy and Syn.Speech still seems to have higher and faster performance. Any next ASR solution (if any) will be open-sourced as well
