Seven AI voice changers ranked for disguising your voice, from Voicemod and ElevenLabs to free, fully local Applio, with which run in real time and which keep your audio on your own computer.
AI voice conversion replaces the sound of your voice with a different one. That's much harder to undo than a pitch shift, which researchers have shown can be reversed.
Voicemod is the best overall pick: real-time, easy to set up with Discord, OBS and games, and free to try.
ElevenLabs Voice Changer gives the most natural results for recorded audio, but it runs in the cloud, so your real voice is uploaded.
Applio is the best fully local option. It's free and open source, and nothing leaves your computer, though you'll need a decent graphics card.
A new voice isn't enough on its own. Your word choice, background noise and file metadata can identify you too.
We weighed how convincing and natural the converted voice sounds, whether it works live or only on recordings, whether your audio stays on your computer or goes to a company's servers, how easy it is to set up, and what it costs.
The classic way to disguise a voice is to shift its pitch up or down. That's quick, but it keeps the shape of your voice intact, and researchers have built systems that estimate the shift and undo it. A 2020 study by Zheng and colleagues restored pitch-shifted voices well enough to bring speaker-verification errors down to about 7%, against 30% for an earlier method, on noisy real-world recordings. The same method struggled to undo AI voice conversion.
AI voice conversion works differently. It keeps your words, timing and intonation, but replaces the timbre of your voice with a different speaker's, so there's no simple setting to reverse. It isn't foolproof: in the VoicePrivacy research challenges, attackers could still identify some speakers from anonymized audio, just with much more difficulty. For most uses, though, it's a far stronger disguise than a pitch shift.

Voicemod is a real-time voice changer for Windows and Mac that sets itself up as a virtual microphone, so it works in Discord, OBS, Zoom and games.
What works: It has more than 200 voices, including AI voices that Voicemod says were trained with professional voice actors and carry Fairly Trained certification. Setup takes minutes, and Voicelab, on the PRO plan, lets you build and save your own effect chain. On Snapdragon X Elite laptops, Voicemod says its AI voices run entirely on the device. The free plan gives you a rotating daily selection of voices to try.
What doesn't: Many of its voices are characters (robots, monsters, cartoon voices), which hide who you are but make it obvious your voice is altered. Voicemod doesn't publish its PRO price on its website, so you'll see it only in the app or at checkout.
Best for: Streamers, gamers and anyone who wants a live disguise without technical setup.
ElevenLabs is best known for text to speech, and its Voice Changer re-voices a recording in one of its library voices while keeping your delivery.
What works: It sounds the most natural of the tools here, keeping your pauses, emphasis and emotion in a voice that isn't yours. It's on every plan, including Free with about 10 minutes a month, and Starter costs $6 a month for about 30 minutes. Those credits are shared with every other ElevenLabs tool, so the minutes shrink if you use anything else. Its Voice Isolator, on the same plans, strips background noise, music and room echo out of a recording, which helps remove sounds that could identify where you are.
What doesn't: It works on files, not live audio, with a five-minute limit per conversion. Everything runs in the cloud, so your real voice is uploaded to ElevenLabs. Its use policy also bans using a voice to deceive people about whether it was made by AI, so an anonymous show should say the voice is synthetic.
Best for: Podcasters, YouTubers and interviewees who record first and want the most natural-sounding disguise.
Applio is a free, open-source app for RVC (Retrieval-based Voice Conversion), the model family behind most community voice models.
What works: Everything runs on your own computer, so your voice never reaches anyone's servers. It's MIT-licensed and free, runs on Windows, Mac and Linux, and has a real-time mode as well as file conversion. You can use one of the thousands of community RVC voice models or train your own, and its interface is much easier to use than the original RVC tools.
What doesn't: You'll want a reasonably strong graphics card, especially for live use, where latency depends on your hardware. You also have to find or train a target voice model, and its README says it will no longer get frequent updates, mainly security and dependency fixes.
Best for: Privacy-minded creators who are comfortable installing software and want nothing to leave their machine.
The w-okada Voice Changer (VCClient) is an open-source, real-time client that runs RVC and Beatrice voice models on your own hardware.
What works: It's built for live use, with a virtual audio output that plugs into streaming and call apps. It runs locally on Windows, Apple Silicon Macs and Linux, and it can hand the heavy processing to a second computer on your network, so a gaming PC can do the conversion while you stream from another. It's free, though updates have slowed: the last release came out in August 2025.
What doesn't: The settings (chunk size, GPU options) take tuning to get latency down, and much of the documentation is written for Japanese users first. The Mac build is unsigned, and it's still labeled beta.
Best for: Streamers who want a local, live AI voice and don't mind some tinkering.
Shift is a real-time voice changer originally made by Supertone, the AI voice company owned by HYBE. HYBE wound Supertone down in July 2026, and Shift moved to a new company, Antinode Audio. Supertone says the service continues with licenses and voices unchanged.
What works: It runs on Windows and Mac with no graphics card needed, and it works with streaming and call apps. There's a free tier with monthly credits, Starter costs $3.99 a month, and Pro costs $14.99, so it's an inexpensive way to get polished character voices live.
What doesn't: Its voices lean toward characters rather than ordinary-sounding people. It doesn't say whether conversion happens on your computer or in the cloud, and the change of ownership leaves its future uncertain.
Best for: Streamers who want a low-cost live voice without a gaming PC.
Respeecher is a speech-to-speech company that works on film and TV, and its Voice Marketplace offers more than 40 licensed voices to anyone.
What works: The voices are licensed from real voice actors, so you're not borrowing anyone's voice without permission. Conversion quality is aimed at broadcast work, and it's available on the web, as a Pro Tools plugin and through an API. Pay-as-you-go starts at $5 for five minutes of conversion.
What doesn't: It costs far more per minute than the other tools, with the Creator plan at $89 a month. It runs in the cloud, and it's built for production work rather than casual live calls.
Best for: Documentary makers and producers protecting an interviewee's identity in a finished piece.
Voice.ai is a free real-time voice changer for PC and Mac with a large community library of voices.
What works: The desktop app is free, works with Discord, Zoom, Meet, OBS and games, and gives you access to thousands of user-made voices.
What doesn't: For anonymity, its terms are the weakest here. Uploading content gives Voice.ai a perpetual, irrevocable license to it, including for model training, and by default its terms let it use your computer's resources for its own computation, a setting you can switch off. It doesn't say whether conversion runs locally.
Best for: Casual users who want a free live voice changer and aren't uploading anything sensitive.
Changing the sound of your voice is one layer. These can give you away too:
Your words: favorite phrases, an accent in your vocabulary and the way you build sentences can be recognized even in a new voice. For sensitive recordings, write out what you'll say, edit it to sound less like you, then read it.
Background sound: room echo, traffic, a pet or a church bell can place you. Record somewhere quiet, or run the audio through a noise-removal tool before conversion.
Metadata: audio files can carry the device, software and time they were made with. Export a fresh file from your editor and strip metadata before you share it.
The service itself: a cloud tool receives your real voice. The Electronic Frontier Foundation's AI privacy guide suggests a simple test: if a feature still works with your internet off, it's probably running on your device.
Disguising your own voice is legal for things like streaming, podcasting and protecting a source. Using one to pass yourself off as a real person, to commit fraud or to harass someone can be illegal, and ElevenLabs, Respeecher and Voice.ai ban it outright in their terms. With the open-source tools, the legal responsibility is yours. Your recordings can also count as biometric data in some places: Illinois's Biometric Information Privacy Act covers voiceprints, so check a service's privacy policy before uploading your voice.
Voicemod for live use, because it's easy and works in most apps. For recorded audio, ElevenLabs sounds the most natural, and Applio is the best choice if you don't want your voice to leave your computer.
Simple pitch shifting can be reversed, and researchers have shown it. AI voice conversion replaces your voice's timbre, which is much harder to undo, though not impossible.
Yes. Applio and the w-okada Voice Changer are free, open source and run entirely on your own computer, though both work best with a graphics card.
No. It converts recordings you upload, up to five minutes at a time. For live calls or streams, use Voicemod, Shift, Applio's real-time mode or the w-okada Voice Changer.
Not on its own. Your word choice, background sounds and file metadata can identify you, so pair the voice changer with a script, a quiet room and a clean export.
