A new kind of
research lab

Bridging the human-machine divide

our approach

Human communication
is like a dance

Human conversation is a rhythm—every glance, pause, and tone changes the meaning. At Tavus, we study that rhythm, designing AI that understands emotion, intent, and timing as one signal. We’re building systems that don’t just respond, they move with you.

The Dance

we study and pioneer

We’re building AI that feels human—machines that see, listen, and respond naturally.

Research Directive

We’re building AI that feels human—machines that see, listen, and respond naturally.

Models

We build models that teach machines perception, empathy, and expression so AI can finally understand the world as we do.
Our Research
Rendering

Phoenix [4]

Phoenix-4, a gaussian-diffusion rendering model developed to synthesize high-fidelity facial behavior at the speed of human interaction, is the result of building real-time facial animation systems that reproduce subtle, temporally consistent expressions with precise control over motion and identity.
Perception

Raven [1]

Raven-1, a novel multimodal perception model designed to unify object recognition, emotion detection, and adaptive attention within a single contextual framework, emerged from modeling how machines interpret people and environments by integrating visual input, emotional signals, and spatial relationships.
Emotional understanding

Sparrow [1]

Sparrow-1, a transformer-based dialogue model that captures conversational timing, responsiveness, and humanlike interaction flow using multimodal alignment techniques, embodies research into parsing communicative intent, emotional state, and turn-level structure across voice, language, and gesture.

Research areas

We study how intelligence perceives context, emotion, and tone to create AI that understands and acts as humans do.

contextual perception

Understanding meaning beyond words. Tone, timing, intent, and everything unsaid.

Audio understanding

Teaching machines to truly listen. Not just to sounds, but to emotion, cadence, and rhythm.

Agentic interaction

Building systems that act with awareness, not automation. Capable of response, reasoning, and restraint.

human-like speech

Synthesizing voice that carries emotion, not just words. Warmth, hesitation, humor, humanity.

Real-time rendering

Turning intelligence into motion. Seamless, lifelike expression that feels natural and alive.

Conversational intelligence

Making dialogue intuitive and human. Conversations that adapt, remember, and build trust over time.

Sparrow-0: Advancing Conversational Responsiveness in Video Agents with Transformer-Based Turn-Taking

In this paper, we dive into the development and research behind Sparrow-0, exploring the innovative transformer-based approach for turn-taking and its integration alongside Raven and Phoenix models within our Conversational Video Interface (CVI), an end-to-end operating system designed for building responsive video agents.

Ethical and aligned
by design

We believe technology earns trust through honesty, not opacity. Tavus is built on informed consent, transparent systems, and full disclosure—no fine print, no hidden levers. Every model, dataset, and likeness we use exists with permission and purpose. You deserve to know how the magic works, and we’re here to show you.
