[AkiThuong]

Hello livekit devs,
I getting this error after install all the package and plugins and tried everything but pointless.
I'm using Linux Debian and install newest plugins.
I'm using minimal_assitant.py in examples/voice-pipeline-agent
Please help.

_recognize_impl was introduced a few weeks ago in https://github.com/livekit/agents/pull/957/files#diff-a255bcc409229bc883ab7bbf85b3a5a70c3f445b960dc4d7c0753525519ce0bbR68-R84, most likely your livekit-agent was upgraded but the plugins were in the old version. Can you check that with pip list | grep livekit?
