Both packages (piper and piper-tts) provide /usr/lib/python3.14/site-packages/piper/

I don't see a way to change the module name without breaking dependencies.

It might be best to contact upstream (https://github.com/OHF-voice/piper1-gpl) to solve the name conflict.

As the package is at present, git clone followed by makepkg -sri fails, because one of the tests fails. The test fails because it expects to have a voice model (a valid .onnx and onnx.json file) in the same directory as the test code (which is src/piper1-gpl/build/tests/CMakeFiles/piper_test.dir/ ); but there is none there. Instead, the files are at src/piper1-gpl/tests/. There are two work-arounds:
1. don't run any tests:

 git pull && makepkg -sri --nocheck

or
2. do a dance to download the source, then insert links to the voice model files, then the build succeeds:

git pull  
makepkg -o  
mkdir -p src/piper1-gpl/build/tests/CMakeFiles/piper_test.dir/  
ln -s ../../../../tests/test_voice.onnx src/piper1-gpl/build/tests/CMakeFiles/piper_test.dir/test_voice.onnx   
ln -s ../../../../tests/test_voice.onnx.json src/piper1-gpl/build/tests/CMakeFiles/piper_test.dir/test_voice.onnx.json   
makepkg -sri

then the tests should all pass.

These files are only used to test the build. If you do not need that, you can set PIPER_BUILD_TESTS to OFF in build().

Then it goes on to download Chinese files and so on, which on my connection takes awhile, not to mention that I really don't want any extraneous files stored here.

[fixed the log]

@musickiller please explain, which onnx files are you talking about?

The package drags lots of .onnx language files, which I totally don't need. Is there a way to block it I only need English, a small one

@CapSel see https://aur.archlinux.org/packages/piper-tts#comment-1055766

this package conflicts with extra/piper - a mouse configuration tool. can this be solved somehow?

The build error with the vowel asset happens if the full path of the asset file is too long, so it fails when building in a directory with a long path. As Schlaefer mentioned, there's an upstream bug report for this: https://github.com/OHF-Voice/piper1-gpl/issues/126

The build fails using an AUR builder like paru which builds packages under a path like ~/.cache/paru/clone/piper-tts/piper1-gpl/ sice that makes the file paths too long. The package builds if it's built in to a shorter path like ~/piper-tts/.

@kagetora13, try to build in a clean environment (extra-x86_64-build) without AUR helper.

To install dependencies not in the repository, you can use -I, e.g. extra-x86_64-build -- -I ../python-pathvalidate/python-pathvalidate-3.3.1-1-any.pkg.tar.zst.
