Set up audio for reliable classroom captions.

Teacher voice first. Lapel mic where possible. Avoid distant pickup in noisy rooms.

Capture the teacher voice clearly

Cleaner teacher audio gives captions the best chance to stay readable in real time.

Best starting point

Use the simplest setup that gets the teacher voice closest to the mic.

Recommended: lapel mic clipped near the teacher voice.
Acceptable: laptop mic in a quiet room for early testing.
Avoid: relying on distant room pickup in noisy spaces.

Pass

  • Mic clipped near the teacher voice.
  • Short caption check before students join.
  • Teacher voice clearly louder than room noise.

Use with care

  • Laptop mic in a quiet room.
  • Teacher staying close to the device.
  • Small pilot lesson before wider use.

Avoid

  • Distant pickup in noisy rooms.
  • Heavy fabric rubbing against the mic.
  • Fans, projectors, or student chatter near the mic.

Quick room check

Clip the mic close to the teacher voice.
Reduce obvious background noise where possible.
Run a short caption check before the class starts.
