Piper TTS FileNotFoundError

[Gandalf-the-Blue]

Hi, I'm trying the following command for local piper-tts audio. I downloaded the
piper_linux_x86_64.tar.gz from https://github.com/rhasspy/piper/releases/tag/2023.11.14-2 and extracted and dumped the contents into the same folder as the epub_to_audiobook folder and downloaded the voice model I wanted = en_GB-cori-high.onnx

python3 main.py ./book/book.epub ./book/audio/ --tts piper --model_name ./en_GB-cori-high.onnx

I'm getting the following error, and for some reason after I confirm the cost ($0.00 Yay!) I run into the following issue. Can you help me out here?

Hi. Did you only 'dumped the contents into the same folder as the epub_to_audiobook folder' but not added it into path?

The current code needs to execute piper-tts directly.

epub_to_audiobook/audiobook_generator/tts_providers/piper_tts_provider.py

Line 62 in 25d9e52

"piper-tts",

It's in the same folder but called piper - made sure it was executable. Also tried changing the code to piper and rerunning, resulting in the error

Hi @Gandalf-the-Blue. I just changed the piper related code in #84. Maybe you can try again.

I updated piper related parameters, you can check this https://github.com/p0n1/epub_to_audiobook?tab=readme-ov-file#examples-using-piper-tts for latest examples.

Besides, you can specify your custom path to the piper executable by using the --piper_path parameter, like:

python3 main.py "path/to/book.epub" "path/to/output/folder" --tts piper --model_name <path_to>/en_US-libritts_r-medium.onnx --piper_path <path_to>/piper

Hey so I tried this again, doing the whole thing again and now I get this errror -

I should also add, that when I tried the piper examples from their git repo - I had to add the --config and point it to the model json file to get it to work.

I see the error what(): Model config doesn't exist in your log. Not sure if you put model and config into the same folder. I just put model and config file in the same folder with the main.py script so it's working. I'll add an option like --piper_ config later to handle this issue better.
