@nickfisherau Nice. Did you publish any details about your alignment code?
For post-edit - maybe #Praat is easier for #speechtech?
I recently did phone alignment tool as a gift to Czech #phonetics and minimizing dependencies (and install hassle), I finally went without anything like Kaldi, using just very basic #Pytorch for NN AM training and then alignment. I guess going zero-up was really easier than decomposing some big thing like Whisper.
