Amazon Connect and Deepgram

Integrate Deepgram’s Speech-to-Text (STT) and Text-to-Speech (TTS) models directly into Amazon Connect and Amazon Lex to power intelligent IVR systems and virtual voice agents.

This guide explains how to integrate your Deepgram models into Amazon Connect flow.

Overview

Amazon Connect is AWS’s cloud-based contact center platform, and Amazon Lex provides tools for quickly building conversational chatbots. With Deepgram integrated into Connect, organizations can seamlessly replace AWS Transcribe and Polly with Deepgram’s STT and TTS models—without modifying their existing Connect flows or operational logic.

This integration supports Deepgram-hosted customers only. Support for self-hosted deployments will be added in a future phase.

Architecture

  • Connect/Lex → Deepgram (STT): Live caller audio is streamed to Deepgram for real-time transcription.

  • Deepgram → Connect/Lex: The transcript is returned instantly for intent recognition or routing logic.

  • Connect/Lex → Deepgram (TTS): Lex sends text to Deepgram TTS model to generate natural spoken responses.

Prerequisites

Before starting:

  • An active Deepgram account
  • An active AWS account
