Browser and microphone
Oral assignments, roleplay, live exams, and some TA interactions require a working microphone and a supported browser.
Recommended browsers
| Browser | Support |
|---|---|
| Google Chrome | Recommended |
| Microsoft Edge (Chromium) | Recommended |
| Safari | Supported; verify microphone permissions each session |
| Firefox | Supported; test before high-stakes exams |
Keep the browser updated. Avoid Internet Explorer.
Microphone permissions
- When Coraltalk prompts for microphone access, choose Allow.
- If you previously blocked access:
- Chrome/Edge: Click the lock icon in the address bar → Site settings → Microphone → Allow
- Safari: Safari → Settings → Websites → Microphone
- Reload the page and restart the assignment.
Hardware checks
- Select the correct input device in system settings (Bluetooth headsets sometimes disconnect).
- Close other apps using the microphone (Zoom, Teams).
- Test in a quiet room; reduce background noise for better transcription.
Camera (live exams / video)
- Allow camera when prompted for live exams or vid tickets.
- Check physical camera shutter switches on laptops.
Mobile devices
Mobile browsers may work but desktop Chrome/Edge is best for exams. If issues occur, switch devices early — do not wait until the deadline.
Firewall and school networks
Some school networks block WebRTC or media devices. Try a home network or contact IT to allow Coraltalk domains.
