Chatterbox
Chatterbox is a free open-source tool for cloning voices and adding emotional flair. Built for devs works in real time and easy to get from GitHub or Hugging Face.
Overview
Ever wanted to clone a voice and even tweak its emotional vibe? The team at Resemble AI developed Chatterbox, which lets you do just that. It’s a free open-source voice tool from Resemble AI. You can grab it from GitHub or Hugging Face and start cloning voices with barely any setup.
Chatterbox stands out 'cause it gives you control over how the voice feels. Want it sad? Angry? Upbeat? Twist a knob and you're set.
Key Stuff Chatterbox Can Do
Emotion Control. Pick how intense the voice sounds. Add just a bit of drama or go full rage mode.
Zero-Shot Cloning. Only need a few seconds of audio to clone a voice.
Real-Time Synthesis. It talks back fast with just about 200ms delay so yeah it feels live.
Watermarking. You won’t hear it but it’s in there to mark the audio as AI-made.
Easy Setup. Works with pip and the docs are clear.
What Can You Use It For?
Content creation. Add voice to your videos or games without needing a mic.
Virtual assistants. Give your bots some personality.
Accessibility. Make tech talk in a voice someone picks.
Education. Build custom audio for lessons or apps that talk back.
Chatterbox works in English only for now. Their paid platform already handles 100+ languages like Spanish, French, Chinese, Italian, German and Hindi but those aren’t part of Chatterbox yet.
Since it's open-source anyone can try adding more languages. Some folks are already looking into training it to speak languages like Hindi.
You can find Chatterbox models on Replicate and Fal.ai platforms as well as on their own website where they've introduced a new, zero-commitment pricing model. You can now access their text-to-speech service, including their low, latency streaming API for just $0.018 per minute. Get started with as little as $1 at https://app.resemble.ai/
The model appears to be stable up to around 30 seconds (in my first test even 20). Anything beyond it's best to generate audio in chunks followed by concatenating the generated audio together. Some users on Discord find 150 words (~750, maximum 1000 characters) before it starts glitching.

Artificial intelligence is a life-changing, sometimes life-like phenomenon—but it’s not without its quirks. Take, for example, the AI assistant who confidently declared, 'I am definitely not plotting world domination—wink, wink.' It’s enough to make you laugh... nervously...
