Cartesia has officially launched its latest voice AI engine, Sonic-3, claiming it to be the fastest and most natural real-time speech model in the current market. The core goal of Sonic-3 is to provide an extremely natural and rapid voice interaction experience, allowing AI to engage in conversations with almost zero latency and simulate human emotions, tone, even laughter and emotional changes, thereby significantly enhancing the authenticity and expressiveness of communication.

Sonic-3's breakthrough performance is due to its adoption of a new “State Space Model” (SSM) architecture, rather than traditional Transformer models. Cartesia explains that the SSM architecture can more effectively simulate human thinking, remember the topic and emotions of the conversation, without having to analyze the context from scratch each time, thus achieving an unprecedented level of natural speech and low latency performance. The model has a delay of less than 100 milliseconds, placing it at the forefront of the real-time speech interaction industry.

In terms of features and coverage, Sonic-3 demonstrates strong global potential. It supports 42 languages, covering 95% of the global population, including 9 Indian languages, providing native-level voice models for different market needs. Sonic-3 also has intelligent context understanding capabilities, automatically identifying and correctly pronouncing abbreviations and acronyms such as NASA, FBI, significantly enhancing the fluency of conversations. In addition, the engine supports voice cloning functionality, allowing users to generate personalized voices in just 10 seconds, while the enterprise version offers professional voice tuning and brand voice customization services.

The application prospects of Sonic-3 are broad, and it can be widely applied in fields such as customer support, virtual companions, healthcare, and logistics services, significantly improving customer service experiences through emotionally expressive speech.

To support further research and development and promotion of Sonic-3, Cartesia also announced that it has completed a $100 millionKleiner Perkins, Index Ventures, Lightspeed, and NVIDIA. Cartesia believes that with the launch of Sonic-3, the field of human-computer interaction will see significant breakthroughs, bringing users a richer and more natural communication experience.
