description

Use when writing or reviewing Java code in this repo that calls Deepgram Conversational STT v2 / Flux over `/v2/listen`. Covers `client.listen().v2().v2WebSocket()`, `V2ConnectOptions`, `onTurnInfo`, and turn-aware close handling. Use `deepgram-java-speech-to-text` for standard v1 transcription and `deepgram-java-voice-agent` for fully interactive assistants. Triggers include "flux", "conversational stt", "listen v2", "turn detection", "end of turn", and "eot".

Using Deepgram Conversational STT / Flux (Java SDK)

Turn-aware streaming transcription over /v2/listen for conversational audio.

When to use this product

• You want explicit turn events, not just regular interim/final transcript chunks.
• You are building conversational UX where end-of-turn timing matters.

Use a different skill when:

• You need general-purpose STT over REST or classic streaming → deepgram-java-speech-to-text.
• You need a hosted interactive assistant → deepgram-java-voice-agent.
