Mic Bluetooth Speaker is a free Android app that turns your phone into a live, wireless microphone. Speak into the phone and your voice plays instantly through any Bluetooth speaker or earbuds, so it works as a portable PA system, a voice amplifier or a karaoke mic. It also has a voice changer with more than a dozen effects, hold-to-record voice clips, and a Share as Video feature for Snapchat, Instagram, TikTok and WhatsApp status.

Features
Live broadcast to any Bluetooth speaker or earbuds
Route your microphone straight to a paired speaker in real time. Pick the speaker from inside the app, drag the microphone sensitivity and volume faders, and watch the live level bars. It is made for announcements, teaching, presentations and small events.
A voice changer with more than a dozen effects
Robot, Chipmunk, Deep, Baby, Monster, Alien, Echo, Megaphone, Telephone, Old Radio, Ghost, Drunk and Parrot. Switch effects instantly while you talk. Reverse works on recorded clips.
Hold to record, slide up to lock
Press and hold the record button for a quick push-to-talk clip, or slide up to lock it and record hands-free for up to 10 minutes. Play the clip back in any voice, save it to your Music folder, or share it.
Share your voice as a video
Snapchat, Instagram Stories, TikTok and WhatsApp status do not accept plain audio files. Mic Bluetooth Speaker turns any clip or saved recording into an MP4 video with an animated waveform that they all accept.
Reverse: say it backwards
Record a short word and play it back in reverse. Send it to a friend and dare them to work out what you said. Short, slow words, such as a friend's name, are the funniest.
Record your live broadcast
Record what you hear while you broadcast, with all your effects applied. A recordings sheet lets you play, share or delete each take, and files are saved to your Music folder.
Audio tools for clear, strong sound
A two-band equalizer, pitch control, Boost, automatic gain control, a noise gate and feedback reduction help when the room is noisy, the speaker is far away or the speaker starts to whistle.
Private by design
Your live audio is processed on your phone and never uploaded. There is no account and no sign-up. Nothing is recorded unless you choose to record and save it.

Frequently asked questions
What is Mic Bluetooth Speaker?
Mic Bluetooth Speaker is a free Android app that uses your phone's microphone to send your voice live to a Bluetooth speaker or earbuds. It also includes a voice changer, push-to-talk recording and a way to share voice clips as videos.
How do I use my phone as a microphone for a Bluetooth speaker?
Pair the speaker with your phone in Android's Bluetooth settings, open Mic Bluetooth Speaker, allow the microphone permission, and tap Start. Whatever you say into the phone plays through the speaker.
Why is there a delay between my voice and the speaker?
Bluetooth audio adds a short delay, about 0.2 seconds in real-world use, and this is inherent to the Bluetooth audio standard rather than to the app. It is fine for announcements, talks and singing along, but you will notice it if you try to speak in time with a video.
Why does my speaker whistle or echo, and how do I stop it?
That is feedback: the speaker's sound is going back into the phone's microphone. Keep the phone away from the speaker, lower the speaker volume or the microphone sensitivity, turn on feedback reduction in Audio tools, or listen on earbuds.
Does it work with earbuds and headphones?
Yes. It works with any Bluetooth speaker, earbuds or headphones that your phone can play music through. If no Bluetooth device is connected, the phone's own speaker can be used, but a Bluetooth speaker or earbuds keep the sound clean and free of feedback.
Is it free, and is there a subscription?
The app is free and supported by ads. A single one-time purchase removes the ads. There is no subscription.
Does the app record or upload my voice?
No. Your live audio is processed on your device and never uploaded. Nothing is recorded unless you choose to record and save a clip. The free version shows ads from Google AdMob, which collects limited advertising data. See the privacy policy for details.
Which phones does it work on, and is there an iPhone version?
It works on Android 8.0 or newer. It is an Android app, and there is no iPhone version at the moment.
