Here’s the fastest way to get microphone access for the Claude app:

  1. Open Claude and start a voice chat or tap the microphone / sound-wave icon. Claude should trigger the permission request when voice mode starts.
  1. On your phone, allow microphone access when prompted. If you blocked it before, open your device settings, find Claude, and switch Microphone to allow.
  1. If you’re on desktop, make sure your browser allows mic access for claude.ai, then refresh the page and try again. If the browser prompt was denied, change the site permission from the lock icon in the address bar.
  1. Close other apps that might be using the microphone, like Zoom or recording tools, because they can interfere with Claude’s access.

Common fixes

  • Restart the Claude app after changing permissions.
  • Update to the latest app or browser version.
  • Try a different supported browser on desktop if the icon still doesn’t appear.
  • If voice mode is still missing, the feature may be rolling out gradually for some accounts or regions.

What it should look like

Once mic access is working, you should see the voice icon become active and be able to speak naturally into Claude.

TL;DR: tap the voice icon, allow microphone access, and if it fails, enable mic permission in app settings or browser site settings, then refresh/reopen Claude.
