# Introduction

> Detect AI-generated audio with high confidence and simple APIs

## Why Aurigin

Aurigin's API provides dual-layer voice security:

1. **Deepfake Detection** - Instantly verify whether audio is AI-generated by detecting tell-tale acoustic and statistical patterns of AI-generated speech
2. **Voice Identification** - Confirm who is speaking by matching voice samples against enrolled voiceprints

Together, these capabilities enable comprehensive voice fraud prevention and identity verification. Security teams, financial institutions, and platform providers use Aurigin to block fraud, safeguard communications, and maintain trust with their users.

## How it works

### Deepfake Detection

1. Send your audio file to `POST /predict`.
2. Receive predictions and confidence scores indicating if the voice is authentic or AI-generated.

### Voice ID

1. Enroll a user's voice with `POST /voiceid/enroll` to create a voiceprint.
2. Verify identity with `POST /voiceid/verify` to match voice samples and detect deepfakes simultaneously.
