Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

Thank you! I've been pulling my hair out for the past few hours over this, and never realized that it was due to a container upgrade. Holding the container back at the older version solved this for me until this bug is fixed.

Seems to be an upstream issue in wyoming-piper: rhasspy/wyoming-piper#20

Rolled back to 1.6.3-ls75 in the interim.

[thespad]

The only real difference between ls75 and ls76 is installing from pypi because the new upstream repo (https://github.com/OHF-Voice/piper1-gpl) doesn't publish prebuilt binaries on github.

It does also mean the piper binary is executed from the python venv rather than /usr/share

[thespad]

Ah, it looks like the master branch has merged in the full support for piper1-gpl but there's no release that does. We might have to roll back to using the really old piper binary from like November 2023 until they resolve that.

Man, I thought I was going mad with this!

Hello, same issue for me with version 1.6.3-ls81, rolling back to 1.6.3-ls75 fixed the issue
