Not a chatbot
Not a chatbot. A reasoning agent.
Most automated answering solutions follow scripts. Stagee Core does not. It reads the caller real intent, adapts the response to the conversation context, and acts on the reservation system in real time.
It is built on a low-latency voice architecture combining speech recognition (ASR), natural language understanding (NLU), and speech synthesis (TTS), all optimized for the rhythm of a real phone conversation.

Technical capabilities
What Stagee Core can do.
Hears like a person hears.
Speech recognition with sub-80ms latency. Handles regional Portuguese accents, dining room background noise, and hospitality-specific terms (dishes, ingredients, allergens).
Understands what the client actually means.
Semantic NLU with restaurant-specific prompt engineering. Does not follow scripts.
Knows when to hand off the call.
When the conversation exceeds what the agent can handle, it transfers to the team. The written call summary is available in the portal.
Follows the conversation from start to finish.
Persistent context throughout the call. Automatic post-call summary with intent and collected data, accessible in the portal.
A voice that sounds like a person.
