Tavus Releases Emotionally Intelligent CVI Platform: Three Core Models Drive Real-Time Video Interaction with Digital People

introductory

The field of human-computer interaction is undergoing a profound transformation, and Tavus, a company specializing in the development of advanced AI interaction technologies, has been driving this change. Last year, Tavus launched what was then called the world's fastest Conversational Video Interface (CVI), opening the door for developers to build real-time video interaction applications.

Now, Tavus has taken another step forward with the release of its new CVI platform for emotional intelligence. At the center of this platform are three breakthrough AI models: Phoenix-3, Raven-0 and Sparrow-0, which together give AI unprecedented ability to perceive, understand and express.

CVI platform: technical analysis

The new CVI platform is more than a tool, it is a complete ecosystem designed to make human-computer interaction more natural and efficient. It combines visual perception, natural language processing and advanced rendering technologies to realize the following key features:

1. Real-time: The CVI platform is optimized for low-latency scenarios and can support smooth real-time video conversations.
2. Emotional Intelligence: Through deep learning models, the CVI platform is able to understand human emotions and respond accordingly.
3. Full face rendering: More than just lip synchronization, the CVI platform is able to generate subtle expressions across the entire face for a more realistic AI image.
4. Ease of use: Tavus Provides a concise API for developers to easily integrate the CVI platform into their applications.

Core models: Phoenix-3, Raven-0 and Sparrow-0

The CVI platform's emotional intelligence and real-time interaction capabilities are made possible by three core models developed by Tavus:

Phoenix-3 Beta: Gaussian diffusion-based full-face rendering

Phoenix-3 is a rendering engine based on Gaussian diffusion modeling. While traditional facial animation techniques usually focus only on the movement of the lips, Phoenix-3 is able to generate subtle expressions of the entire face, including the movement of the eyebrows, cheeks, eyes and mouth.

The technical advantages of Phoenix-3 are:

• Gaussian diffusion modeling: The Gaussian diffusion model is capable of generating more stable and higher quality images than the traditional GAN (Generative Adversarial Network) model.
• Full face control: Instead of just controlling the lips, Phoenix-3 is able to finely control the movement of muscles throughout the face, resulting in richer expressions.
• Real-time rendering: Phoenix-3 is optimized for real-time rendering and generates high-quality facial animations with low latency.

Raven-0: Visual Perception and Emotional Understanding

Raven-0 is a visual perception model that gives the CVI platform the ability to "see" and "understand". Raven-0 not only recognizes objects, but also captures human movements, gestures, and micro-expressions to infer the emotional state of the user. Raven-0 not only recognizes objects, but also captures human movement, gestures and micro-expressions to infer the user's emotional state.

The technical highlights of the Raven-0 are:

• Continuous visual processing: The Raven-0 is capable of processing continuous video streams, tracking user movements and expression changes in real time.
• Multimodal fusion: Raven-0 can combine visual information with information from other modalities (e.g., speech) to more accurately understand user intent.
• Emotion Recognition: The Raven-0 recognizes a wide range of basic emotions and is able to capture more subtle emotional changes.

Sparrow-0: Transformer-based rotating dialog management

Sparrow-0 is a program based on the Transformer models the dialog management engine. It is responsible for controlling the pace of the conversation and deciding when the AI should talk and when it should listen.

Sparrow-0's technology is characterized by:

• Transformer model: The Transformer model has been a huge success in the field of natural language processing, and Sparrow-0 applies it to dialog management to enable a better understanding of the context and semantics of conversations.
• Rotational mechanisms: Sparrow-0 is able to predict the turn of a conversation to avoid interrupting the user or having long silences.
• Low latency response: Sparrow-0 is optimized to respond in less than 600 milliseconds, ensuring smooth conversations.

From a technical perspective, Sparrow-0 uses the Transformer model, a deep learning architecture originally designed for natural language processing tasks. It specializes in processing sequential data, making it well-suited to understanding the flow and context of conversations. By analyzing conversation patterns, including intonation, pacing, and semantics, Sparrow-0 can intelligently determine the best time for the AI to respond.

Model Synergy: Building Emotional Intelligence

Phoenix-3, Raven-0, and Sparrow-0 are not working independently, but in close collaboration to build an emotionally intelligent AI interaction system: Raven-0 is responsible for seeing and understanding, Sparrow-0 for listening and speaking, and Phoenix-3 for expressing. Raven-0 is responsible for "seeing" and "understanding", Sparrow-0 is responsible for "listening" and "speaking", and Phoenix-3 is responsible for "expressing".

Response time calculation formula:

Total delay time = T_perceptual + T_{deal with} + T_{add washes of ink or color to a drawing (Chinese painting)}

• T_perceptual: The time required for the Raven-0 model to process visual inputs and extract relevant features.
• T_{deal with}: The time required by the Sparrow-0 model to analyze the context of a conversation and generate a response.
• T_{add washes of ink or color to a drawing (Chinese painting)}: The time it takes to generate facial animations for the Phoenix-3 model and render the final output.

Experience CVI: Interact with Charlie

Tavus provides an AI demo program called Charlie that demonstrates the power of the CVI platform. charlie is more than just a chatbot, he understands context, recognizes intent, and engages in deep conversations.

By interacting with Charlie, users can experience a whole new way of interacting with the CVI platform; Charlie is able to search the web, analyze on-screen content, and generate images for true multimodal interaction.

Developer: Building Emotionally Intelligent Applications

Tavus provides developers with an easy-to-use API to integrate the CVI platform into their applications. Whether it's AI coaching, customer service or interactive sales training, the CVI platform helps developers build more engaging applications.

Summary and outlook

Tavus' release of the CVI platform marks an important milestone in the field of human-computer interaction. By combining advanced AI models with real-time rendering technology, the CVI platform provides developers with a powerful tool that enables them to build more natural, intelligent and emotional AI applications.

As AI technology continues to evolve, we can expect the CVI platform to play an even bigger role in the future, changing the way we interact with machines and bringing more innovation to the fields of education, healthcare, entertainment and more.
