Voice changer · Mac and iPhone

Change your voice in a video: robot, chipmunk, deep and more

A voice changer turns plain narration into a character, a punchline or an anonymous voice, without recording anything twice.

Each effect is processed on your device, only one is active at a time, and switching to another replaces it rather than piling effects on top of each other.

Quick answer

To change your voice in a video, pick one of Zella's 16 voice changers on Mac or iPhone, processed on your device: Chipmunk, Deep, Robot, Echo, Reverb, Megaphone, Telephone, Underwater, Monster, Helium, Alien, Ghost, 8-Bit, Duck, Cartoon and Ogre. On the Mac, tap one in the Sounds tab to transform your whole mic track; on iPhone, apply one to a clip's audio from the Audio button. Tap again to get your own voice back. Free on every tier.

  1. Step 1: Mac: open the Sounds tab

    Scroll to the Voice Changer section, below the sound-effects library.

  2. Step 2: Tap a voice

    Pick Robot, Chipmunk, Deep or any of the others. Zella processes your mic track on the Mac and swaps it in.

  3. Step 3: iPhone: use the Audio button

    Select a clip, tap Audio in the timeline toolbar and choose a voice for that clip's audio.

  4. Step 4: Change a voiceover

    On iPhone, record narration with Audio → Record voiceover, then tap the voiceover strip and apply a voice. Choosing None gives you back exactly what you recorded.

  5. Step 5: Turn it off

    Tap the same voice again on the Mac to return to your normal voice.

A cast of characters, built in

From Telephone and Megaphone to Alien and 8-Bit, with no separate audio app or plugin to install.

Never destructive

On an iPhone voiceover the effect always renders from the untouched original, so effects replace each other and the raw take is never overwritten.

Hide a voice

Use Deep or Robot to keep a narrator anonymous, processed on the device with nothing uploaded.

Does the voice changer work on my whole video or one clip?

On the Mac it transforms your whole mic track. On iPhone you apply it to one clip's audio, or to a voiceover you recorded.

Can I undo a voice effect?

Yes. Tap the same voice again on the Mac, or choose None for an iPhone voiceover, and your original voice comes back.

Is my voice uploaded?

No. Every voice changer runs on your Mac or iPhone.

Is the voice changer free?

Yes. All 16 voices are free on every tier, on both platforms.
