## What we know about Chatterbox

Chatterbox sits in the text-to-speech apis category, where it is production-minded open TTS from a commercial voice company - MIT license, built-in watermarking, and a fast Turbo variant, with Resemble's paid API as the scale-up path. We keep this Chatterbox profile grounded in primary sources, each fact dated to when we last confirmed it.

Chatterbox does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Chatterbox quote, it is the fastest way for us to close that gap.

On capabilities, Chatterbox covers instant voice cloning, emotion / style controls, and self-host / on-prem option. Each of those is verified against Chatterbox's own docs or dashboard, not marketing copy.

Among the 46 text-to-speech tools in our matrix, Chatterbox leads with the 18th-widest language coverage; the fact sheet below has the raw numbers behind that placement.

In total we track 11 verified facts for Chatterbox today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the Chatterbox fact sheet below.
