Mic to speaker megaphone: loud voice amplifier, Bluetooth output & sirens
Turn your phone into a megaphone. Shoutly is a live mic to speaker app: talk into the microphone and your voice comes out of the phone speaker, wired headphones or a Bluetooth speaker in real time — loud, clear and with almost no delay. Use it as a portable PA system, a bullhorn for tours and classrooms, a voice amplifier for events, a karaoke mic or a stage monitor through headphones. 🎙 LIVE MIC TO SPEAKER • Tap on / off or push-to-talk (hold to talk) like a real megaphone • Mic boost up to +24 dB with live level meters • Choose the output: phone speaker, earpiece, headphones or Bluetooth speaker • Keeps running with the screen off — turn it off from the notification 🛡 NO MORE HOWLING • Echo cancel uses your phone's call echo canceller so the speaker doesn't feed back into the mic • Feedback guard detects howling, notches that tone out and lowers the boost automatically • Clear voice and noise gate make speech carry further 🔊 VOICE EFFECTS & ECHO • Megaphone, walkie-talkie with roger beep, AM radio, robot, alien, chipmunk and monster voices • Echo, karaoke, hall and stadium reverb with adjustable amount • Bass and treble controls 🚨 SIRENS & SOUNDBOARD • Wail, yelp, hi-lo and phaser sirens, alarm beep • Air horn, door chime, school bell, referee whistle, applause, buzzer, drum roll and ta-da • Loop sirens and set their own volume 📢 ANNOUNCEMENTS • Type a message and your phone speaks it through the megaphone (text to speech) • Record a message once and repeat it every few seconds — perfect for queues, shops, parking and events • Ready-made phrases and saved messages 🔒 PRIVATE BY DESIGN Audio is processed on your phone only. Shoutly never uploads your voice and stores nothing unless you record a message yourself. 🌍 15 languages · light "Paper" and dark "Night" themes SHOUTLY PRO Unlimited live sessions, every voice effect, echo and siren, repeating announcements, unlimited saved messages and no ads. Choose monthly, yearly (with a 3-day free trial) or a one-time lifetime purchase. Safety: start with a low volume and raise it slowly, keep the microphone away from the speaker, and never use the app to listen to people without their consent.
