Deepgram Reference Architecture

Prerequisites

• A documented audio/transcript data flow, consent/retention policy, approved environment boundaries, and service/data owners.
• Reviewed interfaces for auth, media ingestion, callbacks, observability, storage, and incident response.

Examples

Model a development producer that validates media metadata, sends a request using a scoped project key, receives a signed callback, and records only correlation/state metrics. Promote the same versioned contract through staging before a production canary, retaining a dead-letter/recovery owner and excluding audio/transcript content from telemetry.

Overview

Four reference architectures for Deepgram transcription at scale: synchronous REST for short files, async queue (BullMQ) for batch processing, WebSocket proxy for real-time streaming, and a hybrid router that auto-selects the best pattern based on audio duration.
