Record a new character voice
Speak into the microphone for three to five seconds. MimicMic builds the voice on your iPhone, ready for you to perform the next line.
Voice a whole scene yourself
One voice.
Every character.
No cast to assemble. Pick a character, perform the line, then switch voices and move straight to the next one.
MimicMic is an offline AI voice changer for iPhone: record a line in your own voice and hear it back as an anime or game character, with your timing and emotion intact. It is not a real-time voice changer and not text-to-speech.
Free to download, with 5 free voice conversions. Love it? Unlock it for life with one purchase. No subscription.

Use Apple Watch as your microphone for MimicMic. Record a line, then hear it in your character’s voice on iPhone. Your audio is never uploaded to the cloud.

Every conversion stays in history
Each finished take is saved under its voice automatically. Open history from the result or its Voicebox card to replay, share or delete individual takes. Rename the voice and its older takes still stay connected.

Share one line or the whole set
Export a finished line as a standard WAV, or package every take for one character into a ZIP for a collaborator or editing tool.

Questions
Can one person voice several characters?+
Yes. Pick the character for each line, hold to perform it, then export the result as a WAV. Switch characters and record the next line for a short video, animation, game or tabletop story.
How do I make the characters feel different?+
Change the performance when you change characters. Let the lead speak faster, give the guardian longer pauses, and keep the regent’s emphasis steady. MimicMic preserves your timing and stress, so the acting still comes from you.
What can I import, and in what format?+
WAV, M4A, MP3 and AIFF. A clip needs at least three seconds, and three to five of them go into the voice. Anything too short or near-silent is refused — just pick a take with clearer speech.
Can I make my own voice? Can I use someone else’s recording?+
You can record yourself or import your own audio. But the built-in voices are fictional characters, and using someone else’s recording to impersonate them is not something we support or encourage — you are responsible for having the rights to whatever you import.
Can I save the transformed audio and send it to people?+
Yes. Every result is saved automatically in that voice’s conversion history. Export one line as a standard WAV, or package every take for the same voice into a ZIP, then share it through Messages, Discord, WhatsApp, AirDrop or Files.
Can I organise a larger voice library?+
Yes. Rename any voice, change its icon and color, add custom tags, and reorder or delete it. Search, built-in/custom filters and tag filters help you find the next role; a tag selected in Voicebox also filters the voice picker on the recording screen.
Can I clear recordings but keep my voices?+
Yes. Settings shows the space used by conversion results, staged imports and recording takes. Clear All Recordings asks for confirmation and removes only those audio files; every voice you created stays in your library.
Does voice conversion need the internet? Is my recording uploaded?+
No to both. Every voice model runs on your iPhone’s own silicon, and AI voice processing never uploads your recording to the cloud or any server.
Can I use Apple Watch as a microphone for MimicMic?+
Yes. Record a line on Apple Watch, then hear it in your character’s voice on iPhone. Your audio is never uploaded to the cloud.
Is MimicMic free?+
Yes, it is free to download, and your first 5 voice conversions are free, so you can hear the speed and quality first. If you love it, a one-time in-app purchase unlocks it for life with unlimited use. No subscription.
Any limits? How much space does it take?+
You need an iPhone running iOS 26 or later. Each take is up to thirty seconds — plenty for a long monologue. To keep the computation on-device, about 900 MB of voice models install with the app, and nothing streams afterwards.
Your next scene only needs one performer.
Pick a character, perform the line, then move to the next. Free to download, no account, no cloud upload.
