Sentinel
Real-time voice safety and wellbeing monitoring for AI agents

Sentinel is thymia’s real-time monitoring SDK for voice-based AI agents. It analyses audio and transcripts as they stream, runs safety policies, and returns actionable results — all without storing recordings.
Early access
Sentinel is currently in early access. For access and configuration, contact support@thymia.ai.
How it works
Sentinel sits alongside your voice agent pipeline. You stream user and agent audio (plus transcripts) over a WebSocket connection. Sentinel runs biomarker models and safety policies in real time and returns results through callbacks.
Key capabilities
- Real-time biomarker extraction — Helios, Apollo, and Psyche models run on streamed audio to measure distress, emotion, and clinical indicators.
- Safety policies — configurable rules that trigger when biomarker thresholds are crossed, returning classification levels and recommended actions.
- Progress updates — periodic callbacks showing how much speech has been captured and when biomarker results will fire.
- Platform agnostic — works with any voice pipeline. Drop-in integrations for VAPI, Gemini Live, and LiveKit.
