Using Deepgram Speech-to-Text (JavaScript / TypeScript SDK)

Basic transcription for prerecorded audio (REST) or live audio (WebSocket) via /v1/listen.

When to use this product

• REST (client.listen.v1.media.transcribeUrl / transcribeFile) — one-shot transcription of a finished URL or file. Good for batch jobs, caption generation, offline processing.
• WebSocket (client.listen.v1.createConnection() / connect()) — continuous streaming transcription. Good for live captions, microphone audio, telephony streams, browser or Node realtime apps.

Use a different skill when:

• You also want summaries, topics, intents, sentiment, language detection, or redaction guidance on the same /v1/listen call → deepgram-js-audio-intelligence.
• You need Flux turn-taking and end-of-turn events on /v2/listen → deepgram-js-conversational-stt.
• You need a full interactive assistant with STT + LLM + TTS over one socket → deepgram-js-voice-agent.
