Hume AI

What is it?

Hume AI is an emotionally intelligent AI platform. Its core product — EVI (Empathic Voice Interface) — is a spoken AI assistant that analyses the tone of your voice and adjusts how it responds. If you sound frustrated, it responds with more care. If you sound excited, it matches that energy. The underlying technology uses machine learning trained on large datasets of human emotional expression, covering voice tone, facial movement, and language.

Hume is aimed at developers building applications where emotional context matters: mental health tools, customer service, companions, and interactive voice products.

Who is it for?

• Developers building voice or companion apps that need emotional awareness
• Researchers studying AI and human emotional interaction
• Product teams at companies where empathetic AI could improve user experience (therapy, coaching, customer support)
• Technically curious non-coders who want to experience emotionally adaptive AI firsthand via the demo

The magic moment

Open the EVI demo on Hume's website and speak naturally about something that's been stressing you. Notice how the AI doesn't just respond to the words — it responds to how you're saying them. Its tone softens. It checks in. Compared to every other voice assistant you've used, it feels like a fundamentally different kind of interaction.

Step-by-step setup

1. Go to hume.ai and create an account
2. Try the EVI demo first — no setup required, just click and speak
3. To build with it, go to the API section and generate an API key
4. Install the Hume Python or TypeScript SDK: pip install hume or npm install hume
5. Follow the EVI quickstart guide in the documentation
6. Make your first API call — send audio and receive both a response and an emotional analysis
7. Explore the emotion scores returned with each response to understand how it's interpreting input

Note: if you're not a developer, the interactive demo at hume.ai is worth experiencing even if you never touch the API.
