Case Study: Cerebrium achieves ultra-responsive AI avatar conversations with Cartesia

How Cartesia Powers the World's Most Responsive AI Avatars

Cerebrium, which builds serverless infrastructure for AI teams, sought to create a highly responsive AI avatar for applications like sales training. Their challenge was to minimize latency to simulate realistic human conversations, as even small delays could break user immersion and engagement. They turned to vendor Cartesia and its text-to-speech API to be a key part of their tech stack.

Cartesia provided its low-latency, ultra-realistic voice API to power the avatar's speech. The solution delivered less than 100 ms to first audio latency, enabling the AI to respond to user input in under 500 ms end-to-end. This speed, combined with fine-grained controls for emotion and tone, resulted in voice interactions that are indistinguishable from a human coach, significantly enhancing the user experience for Cerebrium's demo.
