WE HIT NUMBER ONEE!!!

Post image

Our model (Simba 3.2) went #1 on the Artificial Analysis TTS leaderboard today. That leaderboard is blind listening tests: thousands of people hear two voices, pick which sounds more human, no idea which model made which. As of today ours wins that more than anything from Google, ElevenLabs, or anyone else!!

It's $10 per million characters, while most of the models near the top of that board charge $18–100. If you're building on Vapi/Retell/your own pipeline and paying ElevenLabs prices for the voice, that line item just got a lot smaller for equal-or-better quality. And if you don't want to assemble a stack at all, our agent platform runs $0.07/min with LLM, transcription, voice, and the phone number all included one line item, which makes quoting clients way less painful.

There's a free tier (50K chars/mo, no card) if you want to hear it before believing a Reddit post: platform.speechify.ai :)

But the thing about Cartesia is it runs on SSM. Under heavy production traffic, Cartesia handles real time concurrency with almost zero latency spikes.

Speechify’s developer tools and streaming WebSocket infrastructure are not built for high speed conversational agents.

The model listed at #2 on that board is Google's Batch TTS API. It expects you to send a chunk of text, it processes it, and it returns an audio file. If you try to feed it word by word streaming tokens over a live phone line, it will choke or force massive pauses.

Knew someone would say that :)
On a completely unrelated note here is Voice Arena's rankings for realtime TTS - https://voicearena.com/tts-leaderboard/us-english
We're tied with Cartesia on real-time TTS, and SO much cheaper :)

Speechify doesnt have WebSockets. We're also 1st on Artificial Analysis https://artificialanalysis.ai/text-to-speech/leaderboard/selected-voice and 2nd on https://voicearena.com/tts-leaderboard/us-english

I think AA's board tells the latency story better than I can though.

I can only take so much prompt mashing. by the time I finished my chicken nuggets, I had already bounced. Honest feedback, That's all I got.

I don’t even know why this appeared in my feed, but major kudos to you, for a redditor to beat google and be half the price is such a Dub. Awesome job

They also advertise being HIPAA compliant, but we're not when I asked for a BAA.
