minInterruptionWords does not work #785
Description
Describe the bug
minInterruptionWords in agent voiceOptions does not work. When the VAD detects speech but the STT produces an empty transcript, the interruption word count check is skipped due to text being an empty string and thus falsy:
https://github.com/livekit/agents-js/blob/main/agents/src/voice/agent_activity.ts#L615
The Python SDK does not include this text condition, so I'm not sure why this was added when it was ported to TS:
I'm trying to use minInterruptionWords to reduce false positives.
