Hi all! I'm Brandon, cofounder of Cartesia! We’re thrilled to be sharing our work on Sonic, the fastest human-like voice API. As a company, we’re obsessed with making intelligence faster, cheaper, and more accessible for everyone. And we believe that we need fundamentally new AI architectures to get there. We founded Cartesia to build long-lived real-time intelligence for every device, starting with a kernel of architectural innovation: state space models. My cofounders Karan, Albert, and Chris pioneered State Space Models (SSMs) in academia, and our models like S4 and Mamba are now widely adopted across industry and academia. Sonic is built on a new state space model architecture we’ve developed for low latency modeling of high resolution signals - more technical details here soon! Thanks so much for checking us out! Product Hunt users who sign up for a paid tier get 10% off for their first 2 months through next Friday, June 7.

We were looking for the best quality-to-cost ratio, and Cartesia Sonic clearly stood out. After testing multiple alternatives, we chose to stick with Cartesia for its performance and wide range of high-quality voiceover characters across multiple languages.

Cartesia is amazing! They have enabled us to reduce system latency by hundreds of milliseconds – critical to making our conversations feel natural. Their streaming in, streaming out interface, python libraries, and robust and stable services are perfect for our CRTRs. Thanks team!

Cartesia is a game-changer for us. They provide high-quality voice APIs which are extremely fast and budget-friendly.
