UnboundLocalError every time

[bojtalepenye]

When does this happen?

Every single time. Why? I have no idea. But what I know is that no matter what vocie I try, I always get this error: local variable 'ratio' referenced before assignment

Possible solution request?

Maybe this only happens for me. Maybe I am doing something wrong. It would be a big help if somebody explained to me why this happens and how can I solve it.

Here is the error:

This does look like a bug, sorry about that. Can you paste the full exact command you are running?

Also, can you try that same command but with --minratio 0 on the command line as well?

I think I know what's happening but I don't think I'll be able to look into it until later today or tomorrow.

I looked into your post here: https://github.com/aedocw/epub2tts/issues/31 And thought that maybe the file is causing this. Then I converted the epub to txt like you said, but the issue still persisted. Then I cut down the book to like 4, or 5 sentences literally, but still, the error remained. Here is the full command with the --min-ratio 0:

ubuntu@LENOVO-LEGION:~/epub2tts/The Final Irony$ python3 ../epub2tts.py "/mnt/c/Users/lepen_ztxqwq1/Downloads/The Final Irony.txt" --minratio 0 --speaker 307

By the way, I forgot to mention, that one voice works. And that is the default one. If I don't specify a voice with --speaker, then it works. But I really want to use some other voice. So there is that.

[aedocw]

OK knowing the full command is super helpful, this is a problem with choosing a speaker with TTS, should be pretty quick to fix.

[aedocw]

I just realized what's going on. You need to specify speaker as "p307". Without the "p", it ends up trying to use a speaker model that does not actually exist.

Your command should look something like epub2tts sample.txt --speaker p307 (and it should work just as well with an epub).

Thank you very much, how did I not notice that. It works now, but I have another question if you don't mind. :D In the readme file under usage, there is link to another repository: https://github.com/rejuce/CoquiTTS_XTTS_Examples There are a lot of voices there. How could I use for example the "Abrahan Mack.wav" voice?

[aedocw]

Those are Coqui Studio voices, you would use that one for instance this way:

epub2tts mybook.txt --engine xtts --speaker "Abrahan Mack"

Be aware though that without a GPU, using XTTS is likely going to be too slow to be usable.

Glad we sorted this out!
