Empathic Voice Interface (EVI)

Hume's Emotionally Intelligent Voice Interface (EVI) is the world's first voice AI with emotional intelligence. It takes live audio input and returns audio and text transcriptions enhanced by tonal expressiveness data. By analyzing pitch, rhythm and timbre, EVI unlocks additional added features such as vocalizing at the right time and generating empathetic speech with the right intonation. These features make voice-based human-computer interactions smoother and more satisfying, while opening up new possibilities in new areas such as personal AI, customer service, ease of use, robotics, immersive gaming, VR experiences, and more.

We provide a full suite of tools for easy integration and customization of EVI in your applications, including a WebSocket API for handling audio and text transfers, a REST API, and SDKs for Typescript and Python that simplify integration on web and Python base projects.In addition to this, we provide open source examples and web parts as a practical starting point for developers to explore and implement EVI capabilities in their own projects.

Building with EVI

The primary way to use EVI is through a WebSocket connection that sends audio and receives feedback in real time. This allows for a smooth two-way conversation: the user comments, EVI listens and analyzes their expression, and then EVI generates emotionally intelligent feedback.

You can start a conversation by connecting to a WebSocket and sending the user's voice input to the EVI. You can also send text to the EVI and it will read it out.

EVI will respond in the following manner:

• Give a textual response from EVI
• Provides expressive audio feedback for EVI
• Provides transcription of users' messages and measurement data of their vocal expressions
• If the user interrupts the EVI, feedback on this is given
• When the EVI has finished replying, it will give an alert message
• If there is a problem, an error message is given
