Yeah for sure, breaks are really important.
sconv was especially disappointing because it looked so good on metrics during my training, but the cracks really started to show once it entered user testing. Conformer has been so much less stressful in comparison because most user complaints are about near misses (or completely ambiguous speech where the output is not _wrong_ per se if you listen to the audio) rather than catastrophic failure.
There's another interesting emergent behavior with my user base as I make improvements, which is that as I release improved models allowing users to speak faster without mistakes, some users will speak even faster until there are mistakes again.
Edit: Yep! There have been several improvements on editing, though that's more in the user script domain and my work has still been mostly on the backing tech. I'm planning on working on "first party" user scripts in the future where that stuff is more polished too.
