# Introduction

> Welcome to Sayvy AI — Next-generation conversational voice agents and multi-channel automation engine

# Sayvy AI Documentation

Sayvy AI gives engineering and product teams ultra-low latency conversational voice AI infrastructure. Connect SIP trunks, WebRTC bidirectional audio streams, intelligent conversation workflows, and multi-channel automations (WhatsApp & SMS) with zero operational friction.

## Developer Console & API Access

Manage voice agents, view live call transcripts, configure webhooks, and generate scoped credentials directly from the **Sayvy AI Console**.

### Provisioning Credentials

1. **Create Scoped Keys**: Generate dedicated keys with granular permissions (`agents:read`, `calls:dispatch`, `campaigns:manage`).
2. **Set Expiration**: Protect mission-critical deployments with automatic key rotation or non-expiring production secrets.

3. **Secure Your Secret**: Copy and store your secret key immediately in your environment variables or secret manager.

* **Sub-500ms Audio Latency**: Streaming speech-to-text (Deepgram Nova-2), LLM token streaming (Claude 3.5 Sonnet / GPT-4o), and neural text-to-speech pipelines (Cartesia & ElevenLabs).
* **Bi-directional Interruption Handling**: Real-time conversational barge-in allows users to interrupt natural speech smoothly.
* **Multi-channel Execution**: Automatically dispatch WhatsApp follow-ups, trigger webhooks, and log structured transcripts into your CRM.
