the command: python -m aeneas.tools.execute_task .\audio\2.mp3 .\sync_text\2.xhtml "task_language=eng|os_task_file_format=smil|os_task_file_smil_audio_ref=../audio/2.mp3|os_task_file_smil_page_ref=../text/2.xhtml|is_text_type=unparsed|is_text_unparsed_id_regex=f[0-9]+|is_text_unparsed_id_sort=numeric" .\smil\2.smil -vv the results: image

i set up and ran for the first chapter and everything went smooth with: n m delta: 28836 25625 3000

the second chapter results in: n m delta: 39437 33752 3000

added a couple log statements in dtw.py and have determined this is the line where it breaks best_path = aeneas.cdtw.cdtw.compute_best_path( mfcc1, mfcc2, delta ) self.log([u"computing done"])

in further testing, I have found the upper limit to be about 20 min of audio, anything under that seems to work just fine
