What we know about IndexTTS-2

IndexTTS-2 is a text-to-speech apis platform: emotion-controllable zero-shot voice cloning for production use, but under a custom Bilibili license (not OSI-approved) with scale caps and AI-training restrictions. This profile tracks what we have verified about IndexTTS-2, each fact linked to a primary source and dated.

IndexTTS-2 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 IndexTTS-2 quote, it is the fastest way for us to close that gap.

On capabilities, IndexTTS-2 covers instant voice cloning, emotion / style controls, and self-host / on-prem option. Each of those is verified against IndexTTS-2's own docs or dashboard, not marketing copy.

In total we track 10 verified facts for IndexTTS-2 today, and add coverage as the ingestion pass revisits it. Where a number is a vendor claim rather than our own measurement, it is labeled as such on the IndexTTS-2 fact sheet below, and each row links the primary source it came from so you can check our work.

Whether IndexTTS-2 is the right call depends on your use case more than any single spec, which is why the head-to-head verdicts below score it per scenario rather than crowning one overall winner. Use the fact sheet for the raw numbers, and the matchups for how IndexTTS-2 actually fares against the platforms buyers most often weigh it against.
