The world's first 3D immersive voice agent

The Voice-first
Personal Agent

Not a voice that replies — a presence that's there.

Today's voice AI just takes turns — you talk, it processes, it plays a reply. Lulula is real full-duplex: it can interrupt, be interrupted, and stay quiet — wrapped in 3D spatial sound that gives it place, motion, and presence.

The gap

Today's “full-duplex” voice AI is fake full-duplex.

It still works like broadcast: you finish, it processes, it plays back a clip. Real conversation isn't built that way.

01

Turn-based — it can't stop

Tell today's “full-duplex” voice AI to stay quiet and it talks anyway. It's trigger-by-turn, not truly listening.

02

It makes you hit “send”

Humans think while they speak. Round-based agents force you to finish a perfect prompt before anything happens.

03

No body, no room

Most assistants only speak — no position, no movement, no environment. Nothing that feels like being there.

What we build

Three things at once: it talks back, it's there, and it acts.

Real full-duplex

Targeting 250 ms — under the 300 ms humans can perceive. It cuts in mid-sentence, lets you cut in, and knows when to fall silent. Roughly 20% of human talk is back-channel.

3D sound world

Voice, action sounds, and environment cues with real direction and distance — 15° spatial resolution and 40 ambient scenes. It doesn't just speak; it's somewhere.

An agent that acts

More than chat. A new multi-agent core listens, remembers what you want, plans it out, and gets the task done — then routes work to the best cloud model.

How it works

From a half-formed thought to a finished task

1

Just talk

No perfect prompt. No “send”. Start before you've figured it out.

2

Clarify together

It asks, cuts in, and reflects back — in real time.

3

Feel it acting

Spatial voice, action sounds and room tone show what it's doing.

4

It captures the task

The conversation becomes a structured task — recorded, not re-typed.

5

Route to the worker

It hands execution to the right cloud model — with only the context that job needs.

3D audio

3D audio isn't background sound. It's how the agent behaves.

Every sound has timing, a place, a cause, and a meaning — 15° of spatial resolution across 40 ambient scenes.

Voice

you

Speaking, interrupting, reminding — with emotional tone and breath.

Action sound

front

Typing, turning pages, opening a tool, stepping closer.

Environment

around

Room tone, focus mode, distance, a shift in space.

Architecture

The big models are the workers. Lulula owns the interaction — and the context boundary.

Cloud models
  • Coding / writing / execution
  • Powerful task workers
  • Receive only task-specific context
filtered context in →
Lulula · the interaction layer
  • Voice-first, full-duplex interaction
  • Owns your personal context
  • Interruption & clarification
  • 3D sound behavior
  • Keeps the context boundary local
  • Routes each task to the best model

We don't compete with the big models. We make them useful inside real, personal conversation.

Use cases

Built for the messy way real life actually starts

Daily reflection
“I think I messed up that conversation today.”

It helps you reflect, untangle it, and draft the message to make it right.

Planning
“I'm overwhelmed about next week.”

It breaks the week down into a plan you can actually start.

A quiet need
“My nose hurts every time I use tissues.”

It hears the need behind the words — and suggests what to do, or buy.

Creative work
“I have an idea but can't explain it.”

It turns the mess into a PRD, a pitch, a task you can ship.

Technology

Built for low-latency, interruptible, multimodal voice

01

End-to-end, not stitched

One model generates voice, action & ambient sound, and behavior together — not a brittle ASR → LLM → TTS chain that stacks latency at every seam. In training now.

02

Real-time duplex pipeline

VAD, ASR, interrupt detection and streaming TTS, coordinated so you and the agent can overlap — it decides when to listen, pause, cut in, or continue.

03

Emotional voice — trained

25 emotions × 32 tone words, with smooth transitions even between intense states. The hardest channel of all, and it's already done.

04

Data is the moat

High-quality duplex data costs ~1000× more than ordinary audio. Our own pipeline synthesizes multi-emotion, multi-turn, multi-environment data from cheap mono speech.

The takeaway · two convictions

For the first time, AI that's truly by your side.

Lulula is building the real-time voice and 3D sound layer for personal AI — the world's first 3D immersive voice agent. Not a tool. A presence.

Conviction 01

Audio is the most natural home for an always-on agent — always near, never fighting for your eyes.

Conviction 02

Real companionship is presence, not Q&A. Sometimes you just want someone there.
