Technology

The Amigo Care Engine. In-house. Voice-first. Auditable.

Every component of Amigo is engineered and operated in-house — from voice acquisition to signal extraction to care reports. No black boxes. No opaque chains. A single, auditable system designed for clinical environments.
Architecture

Three layers. One care engine. One continuous signal.

Trained on clinical speech corpora, deployed on a real-time voice stack, and tuned into a single care signal — routed to your dashboard, your caregivers, and the family.

The modules

Each module, explained.

Every module is purpose-built for the care signal. No general-purpose black boxes. No third-party detours.

Entry & exit

Voice Engine

Carries the call. Handles natural turn-taking, calm pacing, age-appropriate prosody, and senior-grade hearing accessibility.

Dialogue orchestration

Conversation Layer

Manages the structure of every call — opening, daily-check questions, medication confirmation, cognitive prompts, closure — adapted per senior.

Affective signal extraction

Mood Tracker

Extracts affective state from each conversation — vocal features, lexical markers, and self-report — scored against the senior's personal baseline.

Cognitive markers

Cognitive Index

Tracks recall, fluency, orientation, and engagement across calls. Produces a composite index trended in 7-, 30-, and 90-day windows.

Longitudinal signal store

Mood Signals

Stores per-senior mood, cognition, adherence, complaints, and engagement on a unified time axis — the substrate for trends and alerts.

Conversation continuity

Care Memory

Remembers what matters — stories, names, routines, preferences — so each call feels like a continuation, not an interrogation.

Threshold-based routing

Alert Engine

Evaluates incoming signals against your protocols. Routes soft and red alerts to the right human within seconds, with full audit log.

Family & caregiver outputs

Reports Engine

Generates the weekly family wellbeing report and the pre-visit caregiver brief automatically, signed under your agency's brand.

Architecture principles

How we built it, and why.

In-house, end to end

Voice, signal extraction, memory, alerts and reports are all developed and operated under one roof. One vendor. One audit surface. One accountable team.

Voice-first by design

The senior never sees a screen. The interface is a phone call — the only digital surface every senior already knows how to use.

Signals, not transcripts

Raw conversation is processed into structured clinical-quality signals. Your team works with mood, adherence, cognition — not paragraphs.

Protocol-shaped

Every threshold, escalation route and report cadence is configurable to your clinical protocols — not a generic default.

Privacy by construction

Per-tenant data isolation, role-based access, encryption in transit and at rest, key rotation, and configurable retention.

Audit-grade by default

Every call, alert, score and access event is timestamped, immutable, and exportable for clinical, security and regulatory review.
