That makes me wonder how much of the work is being done by aeneas vs. your own model. If parts of the audio are in a low voice or noisy (which tends to cause aeneas to slip) will subaligner be able to fix that?
Aeneas is used for stretching pre-synced subtitle cue blocks, which is still experimental in subaligner. If durations of cues are correct in you case, there is no need to use this feature and passing in flag -so will switch it off. So why not get rid of stretch and see the difference?
What I know is Aeneas is using DWT which does not guarantee triangle inequality and for low voice or noise, DNN can handle those better with good enough model capacity.
