Overview

Deepgram provides two STT service implementations:
  • DeepgramSTTService for real-time speech recognition using Deepgram’s standard WebSocket API with support for interim results, language detection, and voice activity detection (VAD)
  • DeepgramFluxSTTService for advanced conversational AI with Flux capabilities including intelligent turn detection, eager end-of-turn events, and enhanced speech processing for improved response timing.
Since Deepgram Flux provides its own user turn start and end detection, you should use ExternalUserTurnStrategies to let Flux handle turn management. See User Turn Strategies for configuration details.
