Built for Creators, Not Just Gamers
Voice changers got popular in gaming. Content creators have different needs: a voice that sounds human, works on uploaded files, and fits into a production workflow.
Video Creators
Add character voices to your videos, build a persona, or narrate in a different accent. No voice actor required.
Podcasters
Bring characters to life, stay anonymous, or add variety to solo episodes without extra recording sessions.
Professionals

A Voice Library That Actually Sounds Human
Simplified's voice library uses ElevenLabs AI, the same technology behind major studios and global platforms. The AI reads the pacing, emphasis, and emotion from your original recording and keeps those qualities in the new voice. When you change a voice, it still sounds like something a real person recorded. Not a robotic filter. With 69+ character voices across ages, genders, accents, and languages, there is a voice for every kind of content.

With 69+ characters in the library, finding the right voice matters. Click any character and hear a preview before applying it to your file. You know exactly what you are getting before you commit. No guesswork, no download-and-regret cycle.
Preview Voice CharactersUpload a Video. Get Back a Voice-Changed Audio File.
Most voice changers only accept audio. Simplified accepts video too. Upload an MP4, MOV, WebM, MKV, or AVI file directly. The tool pulls the audio track, transforms the voice, and returns the result as an MP3. You save a manual extraction step. Supports files up to 50MB and up to 15 minutes of audio.

AI Voice Changer FAQs
And some things you'd ask us.
How does the AI voice changer work?
You upload an audio or video file, pick a voice character from the library, and the AI recreates your recording in the new voice. It preserves the timing, pacing, and emotion of your original audio. The output is ready to download as an MP3.
How many voice characters are available?
The library includes 69+ AI voice characters across different ages, genders, accents, and languages. You can preview any character before applying it to your file.
Do I need to install software?
No. The tool runs entirely in your browser. It works on Chrome, Firefox, Safari, and Edge, on desktop, tablet, and mobile.
What audio and video formats does it support?
Audio formats: MP3, WAV, M4A, OGG, FLAC. Video formats: MP4, MOV, WebM, MKV, AVI. The tool automatically extracts audio from video files.
What is the maximum file size and audio duration?
The tool supports files up to 50MB and up to 15 minutes of audio, which covers most podcast episodes, YouTube videos, and short social content.
Can I use the output in commercial projects?
Yes. Content created with the voice changer can be used in YouTube videos, podcasts, social media posts, client work, and other commercial projects.
What is speech-to-speech AI?
Speech-to-speech AI takes an existing voice recording and transforms it into a different voice. Unlike text-to-speech, which generates audio from typed text, speech-to-speech preserves the natural rhythm and emotion of the original recording.
How is this different from ElevenLabs?
Simplified uses ElevenLabs AI for voice transformation. ElevenLabs is a standalone voice platform. Simplified packages the same voice-changing technology inside a broader content tool, so you can go from upload to finished audio without switching between products.
Can I create my own AI voice?
Yes. The tool includes controls for stability, similarity, style exaggeration, and speaker boost so you can fine-tune any character voice. Custom voice creation is also available for more advanced use cases.
What does the emotional range feature do?
The emotional range controls how expressive the AI voice sounds. A higher setting produces more varied, dynamic delivery. A lower setting gives a more neutral, consistent tone. Adjust it to match the energy of your content.
