Deepgram Starter Apps

Clone a working demo and start building. Every starter is a minimal, runnable app you can extend.

1. Pick Your Feature

What do you want to build?

• Transcribe a file → transcription — send audio/video, get text back (REST, Nova)
• Transcribe a live stream → live-transcription — real-time speech-to-text (WebSocket, Nova)
• Generate speech → text-to-speech — send text, get audio back (REST, Aura)
• Stream speech → live-text-to-speech — real-time text-to-audio (WebSocket, Aura)
• Analyze text or audio → text-intelligence — sentiment, topics, intents, summaries (REST)
• Build a voice agent → voice-agent — conversational AI agent (WebSocket, agent.deepgram.com)
• Conversational STT with turn detection → flux — Deepgram Flux STT for voice agents and interactive assistants (WebSocket, /v2/listen)
• Turn-based TTS for a voice agent → flux-tts — Deepgram Flux TTS, streaming synthesis with barge-in (WebSocket, /v2/speak)

Nova vs Flux STT for speech-to-text: use transcription or live-transcription (Nova, /v1/listen) for general-purpose transcription, captions, and batch workloads. Use flux (Flux STT, /v2/listen) when you need built-in turn detection for conversational audio. See the api skill for a full comparison.

Aura vs Flux TTS for text-to-speech: use text-to-speech or live-text-to-speech (Aura, /v1/speak) for one-shot synthesis, non-English voices, and compressed audio. Use flux-tts (Flux TTS, /v2/speak) when you're streaming LLM output to a speaker and need a turn lifecycle and barge-in. See the api skill for a full comparison.

Flux TTS starters exist for node, flask, fastapi, django, and java only — these are the five apps Deepgram officially publishes at Flux TTS template apps. There is no flux-tts starter for the other frameworks; don't construct those URLs. For an unsupported framework, start from the api skill's Flux TTS section and the SDK skills instead.

• Third-party integrations (Twilio, LiveKit, LangChain, Vercel AI SDK, Discord, etc.) → examples skill → https://github.com/deepgram/examples
• SDK-specific code skills (idiomatic imports, async patterns, gotchas) → npx skills add deepgram/deepgram-{lang}-sdk — see the api skill for the full list of 9 SDKs.
