About Cartesia
Cartesia offers Sonic-3, a state-of-the-art text-to-speech (TTS) API designed for creating highly natural and expressive AI voice agents. Unlike traditional TTS, Sonic-3 incorporates AI-generated laughter and emotions, making conversations feel more human and engaging. It boasts ultra-low latency (90ms time-to-first-audio), ensuring real-time, fluid interactions crucial for conversational AI applications. Built on advanced state-space models (SSMs), Sonic-3 provides context-savvy accuracy, handling acronyms and initialisms intelligently, and supports 42 languages. Cartesia also provides Ink-Whisper for fast streaming speech-to-text and Line, a code-first platform for developing and orchestrating complex voice agents. This suite of tools is ideal for developers and enterprises looking to build sophisticated, high-performance voice AI solutions for various industries like customer support, healthcare, gaming, and logistics, with a strong focus on enterprise-grade security and compliance.
