How to use your Android phone as a microphone for a Bluetooth speaker
Built by Alok Singh (Best Latest Apps). Virtual Mic, one of the apps below, is ours. Download counts, ratings and labels are from Google Play (US) on 10 Nov 2026.
Short answer: pair your Bluetooth speaker with the phone, open a mic-to-speaker app such as Virtual Mic (ours), Live Mic to Bluetooth Speaker or Microphone by Wonder Grace, and tap start. Your voice plays through the speaker. If you want the phone to be a microphone for a computer instead, you need a different kind of app, such as WO Mic or AudioRelay.

Steps
- Pair the Bluetooth speaker in Android Settings > Connected devices.
- Install a mic-to-speaker app and allow microphone access.
- Turn the speaker volume down at first, then start the mic and raise it slowly.
- Keep the phone away from the speaker so you don't get feedback (howling).

Virtual Mic (ours)
The Play listing describes a live mic with a waveform, input gain and output volume, reverb, echo and EQ, and recording to M4A or WAV. It works with Bluetooth speakers and wired headphones.
- Pros: recording and effects in the same app; a live waveform shows you're being picked up.
- Cons: contains ads and in-app purchases; a small install base (10K+) and no public rating shown; Bluetooth adds delay, as it does with every app on this list; no desktop client, so it isn't a PC microphone.

FAQ
Can I use my Android phone as a microphone for a Bluetooth speaker?
Yes. Pair the speaker with your phone, install a mic-to-speaker app such as Virtual Mic, Live Mic to Bluetooth Speaker or Microphone by Wonder Grace, then start the mic. Your voice plays through the speaker live.
Why is there a delay or echo when I use my phone as a mic through Bluetooth?
Bluetooth audio adds latency, so you hear your voice slightly late. Keep the volume moderate and move the phone away from the speaker to avoid feedback. A wired speaker or headphones (AUX) has less delay than Bluetooth.
How do I use my Android phone as a microphone for my PC?
Use an app with a desktop client, such as WO Mic or AudioRelay. Mic-to-speaker apps like Virtual Mic play your voice through a speaker or headphones connected to the phone. They don't add a microphone to your computer.
Does Google have a built-in app for this?
Google's Sound Amplifier boosts and filters sound around you, but it plays through headphones and is designed for hearing, not for a PA speaker. For a Bluetooth speaker, use a mic-to-speaker app.
Can I use my iPhone as a mic for a speaker instead?
Yes. See our guide to the best ways to use an iPhone as a microphone, which compares Mic to Speaker - Virtual Mic, Live Listen and other iOS apps.
