VOICE MODELS
Voice AI
Local STT, TTS, VAD, and echo control that let devices hear and speak without the cloud.

§03 / Fig. 03 — Signal path
Speech, reasoning, and response run on-device.

FIG. 03 — Full-duplex voice loop. Mic → STT → SLM (+ memory, guardrails, tools) → TTS → speaker, entirely local. No request ever leaves the device.
§04 — WHY ON-DEVICE
Physical AI cannot wait on a cloud round trip.
THE CLOUD WAY
Mic → network → datacenter → back.

Nothing leaves the chip. Speech, reasoning, memory, tools, and response stay on-device.

§05 — PRODUCTS
Everything an on-device voice agent needs.
AGENT ORCHESTRATION
Agent Harness
C++ runtime to create autonomous agents that reason, plan, and execute multi-step workflows.
EDGE MODELS
Model Catalog
Edge-ready SLMs selected, quantized, and compiled for local reasoning on embedded hardware.
1B – 35BOPTIMIZED PARAMETERS
FIG. 05 — Product overview. Voice AI, agent runtime, and edge models: one stack for devices that need to speak, listen, and reason locally.
§06 — WHY EDGEAI
Three things no competitor has all of.
01
One-stop-shop
The full agentic stack, not a single tool — orchestration, voice, and models in one runtime.
02
Ultra-portable
Hardware-agnostic by design. Build once, deploy across NVIDIA, Qualcomm, Apple, and AMD.
03
Purpose-built
Not a wrapper. Built from the ground up for real-time, on-device execution.
§07 — BY THE NUMBERS

§08 — Meet Friday
An AI that's yours alone.
Friday is a personal assistant that lives entirely on your device — brilliant, always on, and answerable to no one but you.
“Friday, what did I miss today?”
Friday
Two emails worth reading — and a 4 p.m. you almost forgot.
Always on-device — nothing you say ever leaves this machine

§09 — IN THE FIELD
One platform. Every physical frontier.
FIG. 01
Robotics
Talk to your robots. Spoken commands, understood on-device.
FIG. 02
Automotive
An in-cabin co-pilot that works with no signal.
FIG. 03
Aerospace
A mission voice agent where the radio can't reach.
FIG. 04
Defense
Private voice AI in comms-denied environments.

Barge-in and interruption handling for on-device voice agents
Barge-in is the hardest part of a voice agent to get right: hearing yourself over your own TTS, deciding an interruption is real, and stopping in a couple of audio frames. Why the DIY Whisper + llama.cpp + Piper stack breaks it, and how an on-device C++ loop fixes it.

Time-to-first-token: why voice agents live or die on latency
A latency budget for real-time voice agents: the 200ms human turn-taking rule, where cloud pipelines spend 600ms–1.7s, and how on-device buys it back.

How to build an offline voice assistant on NVIDIA Jetson Orin
A builder's guide to running a fully offline voice agent on Jetson Orin — local STT, an SLM, and TTS, with real latency numbers and where the DIY Whisper + llama.cpp + Piper stack breaks down.
