Template Apps

Each template is a runnable demo that streams text to Deepgram Flux TTS over /v2/speak and plays the audio back. Unlike the Flux transcription starters, these use the official SDK’s speak.v2 client on the backend, so the SDK manages the Deepgram WebSocket, authentication, and binary-audio framing for you.

The Python, JavaScript, and Java SDKs ship a speak.v2 client for /v2/speak:

• Python — deepgram-sdk (GitHub)
• JavaScript — @deepgram/sdk (GitHub)
• Java — deepgram-java-sdk (GitHub)

See Getting Started for the speak.v2 code shape. Languages without SDK support yet can connect to the WebSocket directly.
