BUG-15F79EB4: Test: voice stuttering

high · voice · ready_for_review · 2026-08-21T14:34

When using voice mode, the AI stutters and repeats words. Happens with all voice engines.

1. Start voice chat
2. Talk for 30 seconds
3. AI starts repeating words

AI repeats the last word 2-3 times

This patch adds a maximum repetition limit and a context timeout to the `voice_mode.py` file, which should help prevent the AI from stuttering and repeating words in voice mode.
