The Journey of EVI: From Inception to General Availability

Hume AI has been at the forefront of emotional AI research and development. Their expertise and dedication have led to the creation of EVI, a game-changer in the field of conversational AI. The company recently announced a $50 million Series B funding round, led by EQT Ventures, which brings its valuation to an impressive $219 million.

The funding will be utilized to scale Hume’s team, accelerate AI research, and further enhance the capabilities of EVI. General availability of EVI is expected in April 2024, and developers can sign up for notifications to stay updated on its release.

What’s the Power of EVI?

EVI offers a wide range of features and capabilities that redefine the way we interact with AI systems. Let’s explore some of the key attributes that make EVI stand out from its counterparts:

1. Empathic Capabilities: Speaking the Language of Emotions

EVI is designed to respond with human-like tones of voice based on the user’s expressions. It adapts its language to address the user’s needs effectively, maximizing satisfaction. This empathic approach makes conversations with EVI feel more natural and engaging, creating a sense of connection between humans and machines.

2. Seamless Interaction: Recognizing the End of Conversation Turns

One of the challenges in AI-based conversations is the smooth transition between turns. EVI leverages the user’s tone of voice to accurately detect the end of a conversation turn, eliminating awkward overlaps. This state-of-the-art detection ensures seamless interactions, making the user experience more comfortable and fluid.

3. Interruption Handling: Mimicking Human Conversations

Just like a human conversation partner, EVI handles interruptions gracefully. It stops speaking when interrupted and effortlessly resumes from where it left off. This feature enhances the natural flow of the conversation, allowing users to engage with EVI in a manner that feels intuitive and lifelike.

4. Continuous Improvement: Learning from User Reactions

EVI is not a static AI system; it continuously learns and improves based on user reactions. By optimizing for happiness and satisfaction, EVI aims to provide personalized and tailored responses, enhancing the overall user experience. This self-improvement capability ensures that EVI evolves and adapts to individual preferences over time.

The Science Behind EVI: Semantic Space Theory

The foundation of EVI’s emotional intelligence lies in semantic space theory (SST). This data-driven framework for understanding emotions enables Hume AI to train its models and develop products that capture the full spectrum of human emotion. SST maps the high-dimensional nature of emotions and reveals the continuity between emotional states, further enhancing EVI’s ability to comprehend and respond to vocal expressions.

Building with EVI: An Immersive Experience

Developers can harness the power of EVI by integrating it into their applications. Hume AI provides a suite of tools, including a WebSocket API, REST API, and SDKs for Typescript and Python, to simplify the integration process. These resources enable developers to create seamless and immersive voice-based interactions with EVI.

1. WebSocket Connection: Enabling Real-time, Bidirectional Dialogue

The primary way to work with EVI is through a WebSocket connection, which facilitates real-time, bidirectional dialogue between the user and the AI system. By streaming audio input to EVI and receiving responses in real-time, users can enjoy fluid and natural conversations with the AI.

2. Text and Voice Responses: Enhancing User Interaction

EVI responds to user input in multiple ways. It generates text responses, expressive audio responses, and transcripts augmented with vocal expression measures. This holistic approach ensures that users receive comprehensive and engaging feedback from the AI system.

3. Error Handling and Completion Notifications: Smooth User Experience

EVI provides detailed error messages if any issues arise during the conversation. Additionally, it notifies users when it has finished responding, allowing for a more seamless and satisfying user experience. These features enhance the reliability and usability of EVI in various applications.

Empowering Developers: Tools and Resources

To empower developers and facilitate the integration of EVI into their projects, Hume AI offers a range of developer tools and resources. Let’s explore some of the key components:

1. WebSocket API: Real-time Interaction Made Easy

The WebSocket API serves as the primary interface for real-time, bidirectional interaction with EVI. It handles audio and text transport, facilitating smooth communication between the user and the AI system. Developers can leverage this API to create dynamic and interactive voice-based applications.

2. REST API: Customizing EVI to Suit Your Needs

For developers seeking greater customization options, Hume AI provides a REST API. This configuration API allows developers to tailor EVI according to their specific requirements. From system prompts to speaking rates and voice preferences, developers have the flexibility to shape EVI’s behavior and responses.

3. SDKs for Typescript and Python: Simplifying Integration

To simplify the integration process, Hume AI offers SDKs for Typescript and Python. These software development kits encapsulate the complexities of audio streaming and WebSocket communication, making it easier for developers to integrate EVI into their web and Python-based projects.

4. Open-Source Examples and Web Widget: Practical Starting Points

Hume AI provides open-source examples and a web widget to help developers explore and implement EVI’s capabilities.
