The streaming-native voice model now leads the blind, Elo-rated TTS Arena — ahead of Google, ElevenLabs, and every other major provider — while Speechify prices its API below most of the field it outranks.

Speechify's Simba 3.2 model sits at the top of the Artificial Analysis Text to Speech Arena, a blind, Elo-rated leaderboard where listeners compare unlabeled voice samples and vote on which sounds better. In the current standing Simba 3.2 leads with an Elo score around 1,233, ahead of Google's Gemini 3.1 Flash TTS and a field that includes ElevenLabs, Cartesia, and other major commercial providers. It is the first time Speechify's family has held the outright #1 position rather than a top-10 placing.
Simba 3.2 is the flagship of Speechify's Simba voice-model family, exposed to developers through the Speechify Voice API. It is streaming-native — audio begins arriving in chunks as it generates rather than after the whole clip renders — and Speechify tunes it for very low time-to-first-byte, in the sub-300ms range, which is what makes it viable for real-time voice agents and live reading. Its headline capability is expressivity handled at the prosody level: rather than only adjusting speed and pitch, the model shapes the rhythmic and tonal patterns that carry emotion, with a set of expressive styles and SSML control. At launch it is English-first with the language set expanding and a growing curated voice roster; a sibling model, Simba 1.6, covers 30-plus languages and zero-shot voice cloning on the same API.
The through-line is quality-per-dollar. Speechify meters the API by characters of generated speech, on tiers that drop toward roughly $6 per million characters at higher volume — well below most of the models Simba 3.2 now outranks, several of which cost multiples more per character. The previous-generation Simba 3.0 had already broken into the leaderboard's top 10 in May 2026 at around $10 per million characters; Simba 3.2 pushed the family to the top of the board. Treat the exact Elo figure and per-character rates as a snapshot — leaderboard positions and voice pricing both move — and confirm the current standing and prices on Speechify's own pages and the Artificial Analysis leaderboard.
The right read on Simba 3.2 hitting #1 is that the voice problem is now solved and cheap — which means the value has moved to everything around the voice. A leaderboard-topping API hands you a great audio track and stops there. It writes no script, makes no video or images, captions nothing, and publishes nowhere. That gap is exactly what Kompozy fills. Kompozy is a content generation and publishing engine, not a voice model, so the two don't compete — they slot together. Kompozy writes the Blog Article and the script under a Persona Brief so the text you feed the Simba 3.2 API is already on-brand, you call the API to voice it into a clean audio read for a podcast feed or a faceless-video voiceover, and then Kompozy produces everything the API can't and ships it: Clipped and Persona Shorts, brand-exact Carousel Posts, Quote Graphics, Photo Posts, and a Newsletter, scheduled and published across nine social platforms plus blog and email from one queue with Autopilot. For social talking-head video, Kompozy already uses HeyGen's built-in TTS, so Simba 3.2 owns your standalone audio channel while Kompozy owns generation and distribution.
There's also a timely play in the news itself. "The best-ranked AI voice model just got cheap" is a story your audience is searching this week. Drop your take into Kompozy and it fans one point of view into a blog explainer, a carousel, a captioned short, and platform-native posts — and you can voice the blog with the very model the story is about, closing the loop while the news is fresh.
Simba 3.2 is the flagship model in Speechify's in-house Simba voice family, available to developers through the Speechify Voice API. It is streaming-native with very low latency and prosody-level emotion control, and it currently ranks #1 on the Artificial Analysis Text to Speech Arena.
On the Artificial Analysis Text to Speech Arena — a blind, Elo-rated leaderboard — Simba 3.2 currently sits at #1, ahead of Google's Gemini 3.1 Flash TTS, ElevenLabs, and other providers, while Speechify prices its API below most of that field. Leaderboard positions move, so confirm the current standing before relying on it.
Speechify meters the voice API by characters of generated speech, on tiers that drop toward roughly $6 per million characters at higher volume (around $10 on the entry tier) — well below several higher-priced rivals. Verify current rates on speechify.ai, since voice pricing changes.
No. Simba 3.2 synthesizes audio only. It does not write scripts, make video or images, caption clips, or publish to any platform. To turn one idea into a full week of on-brand posts across nine platforms — and voice the audio channel with a model like Simba 3.2 — pair it with a content engine like Kompozy.
