# Dolva API: Voice Intelligence Platform for Developers

> Dolva is a REST API that extracts cognitive and emotional signals from audio. Learn what you can build and how the API is structured.

Dolva is a REST API that analyzes audio recordings and returns structured signals about the speaker's cognitive state and emotional profile. Whether you're building mental wellness apps, conversation intelligence tools, or clinical monitoring solutions, Dolva gives you a simple HTTP interface backed by purpose-built audio ML models.

## What Dolva Does

You upload an audio file — a short voice clip, a conversation snippet, or a longer recording — and Dolva returns JSON containing signal data extracted from the audio. Two analysis types are available:
