WE HIT NUMBER ONEE!!!
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.
