# Voice Verification Workflow

Use the `/verify-by-voice` endpoint to compare two audio samples: a reference audio and a real-time audio recorded by your application.

Authentica analyzes both samples and determines if they match.

## How It Works

1. Provide a `registered_audio` (reference audio)
2. Provide a `query_audio` (real-time audio from your app)
3. Authentica compares them and returns the match result

See the [Verify by Voice API Reference](/api-reference/voice-verification/verify-by-voice) for detailed parameter documentation.
