Atlas Cortex — Intercom & Broadcasting (Part 7)

Room-to-room communication and whole-house announcements via the satellite speaker network.

Overview

Atlas turns the satellite network into a whole-house intercom system with targeted messaging, broadcast announcements, and two-way communication.

Capabilities

Targeted Messages

User (in kitchen): "Tell the kids dinner is ready"
Atlas: "Which room are the kids in?"
User: "Their bedrooms"
Atlas: *plays on bedroom satellites* "Hey! Dinner's ready — come to the kitchen!"

Broadcast Announcements

User: "Announce family meeting in 5 minutes"
Atlas: *plays on ALL satellites* "Attention everyone — family meeting in 5 minutes in the living room."

Room-to-Room Call

User: "Call the garage"
Atlas: *opens two-way audio between kitchen and garage satellites*
Atlas: "Connected to the garage. Go ahead."
User: "Hey, are you almost done out there?"
Garage person: "Five more minutes!"
Atlas: *ends call after silence timeout*

Group Pages

User: "Page upstairs"
Atlas: *plays on all upstairs satellites* "Message from the kitchen..."

Message Types

Type Delivery Two-Way Timeout
Announce TTS on target satellites No N/A
Broadcast TTS on ALL satellites No N/A
Call Two-way audio stream Yes 60s silence
Page TTS on zone satellites No N/A
Emergency Max volume ALL satellites No N/A

Room Zones

CREATE TABLE IF NOT EXISTS satellite_zones (
    id            TEXT PRIMARY KEY,
    name          TEXT NOT NULL,            -- "upstairs", "downstairs", "bedrooms"
    satellite_ids TEXT NOT NULL             -- JSON: ["bedroom-01", "bedroom-02", "office-01"]
);

Zones allow grouping satellites for targeted announcements: "Page upstairs", "Announce in the bedrooms".

Message Personalization

Atlas uses the voice engine (C11) to generate appropriate TTS:

  • To children: Friendly, warm tone — "Hey buddy! Mom says dinner's ready!"
  • To teens: Casual, brief — "Dinner time."
  • Emergency: Urgent, clear — "ATTENTION: Smoke detected in the kitchen. Please evacuate."

Implementation Tasks

Task Description
P7.1 Intercom intent parser — extract target rooms, zones, people, message
P7.2 Message personalizer — adapt tone/voice for target audience
P7.3 Satellite router — deliver TTS audio to specific satellites/zones
P7.4 Two-way calling — bidirectional audio stream between satellites
P7.5 Zone management — create/edit/delete satellite groups
P7.6 Emergency broadcast — max-priority, all-satellite override
P7.7 Pipeline integration — Layer 2 plugin for intercom/announce intents
