The engagement control layer for voice AI

Overview

Attention Labs is the engagement-control layer that decides which speech is actually addressed to a device or agent, in real time and before it acts, so AI responds only when it should & stays silent on the rest.

Their first system, Selective Auditory Attention (SAA), tags every utterance as device-directed, human-directed, or ambient, holds anything below the engagement threshold, and forwards only the addressed audio to any downstream model, on-device or in the cloud, fail-closed by design. It's the missing layer between the microphone and the model: addressee routing, engagement gating, and a clean audio handoff that drops into any voice stack, whatever AI sits behind it.
