Cartesia

Cartesia seeks to address the shortcomings of the legacy voice AI stack with a new model architecture, the State Space Model (SSM), that processes data far more efficiently than the transformer. This makes the SSM more useful for delivering voice AI experiences that resemble authentic human speech patterns. The company has productized the SSM by building voice models with extremely low latency and natural expressiveness. It also offers an agent development platform that allows businesses to easily create voice agents with its models and infrastructure.
