Biggest wins — audio & setup
The setup choices that affect accuracy most, before any tuning.
Audio quality comes first
For live events, input quality usually matters more than any software setting. A clean, consistent audio signal in the correct language is the single biggest driver of accurate captions.
- Microphone source: use a dedicated pulpit, lapel, or line/USB microphone rather than the laptop's built-in mic, which picks up room noise and reverb.
- Levels: aim for a clear, consistent signal — too quiet causes missed words, too loud causes distortion.
- Speaker pace: a natural pace with slight pauses between thoughts is recognized more reliably than fast, run-on speech.
- Correct source language: make sure the session's spoken language matches what is actually being said.
- Fewer target languages: translate only the languages you need.
- Network: use a stable connection and avoid guest networks that block real-time connections.
Rehearse with the real microphone on the real network before going live. This catches the issues that matter most.
