Trillet AI: Gemini in Vertex AI + GKE to reduce call-center voice agent errors and costs

Trillet AI builds a voice application layer for enterprise that automates high-stakes customer interactions such as appointment rescheduling and government follow-ups. The company moved its infrastructure to Google Cloud, using Gemini in Vertex AI as the primary reasoning engine and Google Kubernetes Engine for autoscaling real-time voice traffic. It also used Speech-to-Text and Text-to-Speech for voice interactions, with the model ingesting extensive client-specific business logic and negative constraints.

Architecture

Trillet AI runs its real-time voice application on Google Kubernetes Engine and uses Gemini in Vertex AI as the primary reasoning engine. The model receives large amounts of client-specific business logic and 'negative constraints' to avoid invalid actions, while Speech-to-Text and Text-to-Speech services support live conversations.
