From the beginning, I’ve been in awe that the system does as good a job as it does of matching the audio to each sentence. But the beginning and or end of the sentence audio ends up short part of a word or long. I just reloaded the audio in one of my chapters and regenerated timestamps, but it sti…

Did you try higher bitrate mp3s or M4a files. [image] The transcription of Ukrainian audio lessons is catastrophic Open Forum @BlueSkies305 If the MP3 is incorrectly encoded, our importer is treating part of the frame as silence. Firefox browser is less tolera…

After you posted that, I tried converting the MP3 that I downloaded from Audible to M4A at 320 using Audacity. It was worse than before. Then I downloaded the file from Audible again. Epubor gives the option of MP3 or MP4, so this time I tried MP4 and converted that to M4A at 320bps and it was st…

Sounds like a new problem. Previously it was the player in browser/app. They behave badly with low bitrate. I noticed the problem with timesyncs when playing the same sentence in app and browser. eventhough timestamp is same, the playback don’t match. Problem went away after using higher bitrate. W…

I should have said that this was using the IOS app. I didn’t try to see if it worked properly in the browser. I’ll have to do that.

I tried it in the browser and the original audio sounds the same as on IOS. I already deleted the higher bit rate files and I don’t think it’s worth redoing all of that. The audio of the default MP3 from Audible should be adequate for the AI to determine the start and end of a sentence.

Audio still not consistently matching text in sentence mode
