Chatterbox TTS Online
Speech studio
34 voices · 18 languages
Hear Resemble AI’s Chatterbox without setting anything up — no Python, no GPU, no checkout. Type your text, generate, and download the MP3. It is the same engine that powers this site’s free Standard+ tier.
How it works
Three steps, about a minute
- 1
Paste or write your text
Drop in a script, a paragraph, or a whole article. Longer text is split into parts automatically and joined back into one file.
- 2
Pick a voice and preview it
Almost every voice has a preview you can play before spending anything, paid ones included. Filter by language, then hear two or three before committing.
- 3
Generate and download
Audio comes back in seconds as MP3 or WAV, with a commercial licence on every tier — including the free one.
Examples
Hear it on real scripts
Every clip below was generated here on the free tier — no account, no credits. Play one to hear the voice on that kind of writing, or load the script into the generator and make your own version of it.
TikTok hook
The first three seconds, where the scroll is decided.
“Stop scrolling. You've been doing this wrong your entire life, and nobody told you, because the right way takes four seconds and looks like cheating. Watch.”
Short-form story
Narration for a faceless story clip, built to land in under a minute.
“So my neighbour knocks on the door at eleven at night holding a ladder. Not asking for anything — just holding it. And he says, completely calmly: don't worry, this is about the cat. It was not about the cat.”
Podcast opener
Cold open that sets up the episode without a sponsor read.
“This week: a bank that lost four hundred million dollars because of a rounding error, the intern who found it, and the eight months it took anyone to believe her. It's a story about arithmetic, and it is somehow also a story about how hard it is to be right early.”
Included
What you get
- Free without an account
- Thousands of characters a day as a guest, no sign-up and nothing to install. An account raises the limit; it is not a gate on the tool.
- Commercial use included
- Monetised videos, client work and ads are all fine on every tier. You own what you generate.
- MP3 and WAV export
- MP3 for editors and uploads, WAV where you need uncompressed audio. Speed is adjustable from 0.75× to 1.5× on engines that support it.
- Long text, one file
- Text past the per-request limit is split at sentence boundaries, generated in order, and stitched back into a single download.
- Voices across 18 languages
- Several languages are read by voices trained on that language rather than an English voice reading foreign words — the difference is audible immediately.
- Credits that never expire
- Premium and ultra voices are billed in credits. One-time packs never expire; monthly plans refill every billing cycle instead.
Why people search for Chatterbox
When Resemble AI open-sourced Chatterbox, it did something unusual for the category: it shipped a model whose expressiveness holds up against paid engines, under an MIT license that does not hedge. The result is a model that shows up in every “open-source ElevenLabs alternative” discussion.
The catch is the setup. Running it yourself means a CUDA-capable GPU, a Python environment, and several gigabytes of weights before you hear a single word. This page removes that step: the generator above calls the model in the cloud, so you can judge the output first and decide whether self-hosting is worth it after.
The same engine as our free tier
Chatterbox is not a demo here — it is the engine behind the Standard+ voice on the site’s free tier, running the multilingual variant trained across 23 languages.
That makes this page a fair capability test. If the voice above fits your project, you can keep using it right here at no cost, or take the same model self-hosted knowing exactly how it sounds. If you need something it does not do, the voice picker lets you swap engines and rerun the same text for a direct comparison.
Where Chatterbox fits — and where it does not
A practical guide from running it in production:
- Pick Chatterbox for expressive short clips: character dialogue, reactions, lines where energy matters
- Pick Kokoro (also free here) for long narration — it is faster and takes 10× more text per clip
- Pick a premium engine when you need voice variety or languages beyond what the open models cover
