Sonic-3 – A real-time voice conversation model launched by Cartesia

What is Sonic-3？

Sonic-3 is the latest AI voice engine released by Cartesia, representing one of the fastest and most natural real-time voice conversation models available today. Unlike traditional Transformer-based systems, Sonic-3 adopts an innovative State Space Model (SSM) architecture, which more effectively simulates human thought processes — remembering conversation topics and emotions without reanalyzing the entire context every time.
This design enables latency below 100 milliseconds, setting a new benchmark in the real-time voice interaction industry.
Sonic-3 supports 42 languages, covering 95% of the global population, including 9 Indian languages, delivering native-level speech quality across diverse markets.
It features intelligent contextual understanding, automatically recognizing and pronouncing acronyms and abbreviations (e.g., NASA, FBI) correctly, significantly improving conversational fluency.
The engine also offers voice cloning, allowing users to create personalized voices within 10 seconds. The enterprise edition provides advanced voice tuning and custom brand voice design for professional use.
