Deepgram is a real-time speech API built for voice agents and call analytics — Nova-3 ships low-latency streaming plus pre-recorded transcription, with diarization, PII redaction, and summarization wired into a single REST + WebSocket surface.
Nova-3 is Deepgram's current flagship model, available in nova-3-general (multilingual) and nova-3-medical. The platform exposes one REST endpoint for pre-recorded audio (/v1/listen) and a WebSocket for live streaming, with diarization, word-level timestamps, PII redaction, and summarization toggled by query parameters.
Best for real-time voice agents, call-center analytics, live captioning, and meeting tools where p50 streaming latency is the product. New accounts get $200 in free credit with no card; pay-as-you-go pricing runs from $0.0048/min streaming and $0.0077/min pre-recorded on Nova-3 monolingual, with a separate per-minute rate for the Voice Agent API.
What it is
Deepgram's Nova-2 is one of the strongest streaming ASR models on the market, with very low latency and good accuracy on conversational audio. HIPAA-eligible, per-minute pricing competitive with self-hosted for modest volume. Last price check: 2026-04-20.
Watch out for: Lower language coverage than Whisper variants; proprietary.
Install / use
Where Deepgram fits · 6 use-cases
Deepgram's strengths cluster around streaming latency, conversational accuracy, and an API surface that bundles agents + ASR + redaction. Pick the card closest to your build — each links to the canonical docs section.
The Agent API wraps Nova-3 STT, an LLM step, and Deepgram TTS behind one WebSocket so you ship a conversational agent without stitching three providers. Drop-in for phone bots, IVR replacements, and in-product voice copilots.
Built-in turn-taking + barge-in
Batch call recordings through /v1/listen with diarize=true and redact=pii to get speaker-labeled, PII-scrubbed transcripts ready for QA scoring and topic mining. HIPAA-eligible on paid plans.
diarize + redact + summarize=v2
Open a WebSocket to wss://api.deepgram.com/v1/listen and stream PCM; interim transcripts arrive word-by-word with timestamps. Common stack for webinar captions, live-event accessibility, and broadcast workflows.
Word-level timestamps inline
Send the episode URL or upload bytes; ask for diarize=true, punctuate=true, paragraphs=true, and summarize=v2 in one call to get a publishable transcript plus a model-generated recap.
Single request returns all artifacts
nova-3-general handles 10 base languages plus regional variants under one model id — useful when you can't predict the input language, or when you need code-switching inside a single utterance.
Detect + transcribe in one pass
Set redact=pii (or fine-grained tags like numbers, ssn) and the transcript ships with sensitive spans replaced by typed placeholders like [PHONE_NUMBER_1] — raw audio is not retained when the no-store option is enabled on enterprise plans.

Yes — this page carries 3 tested setups: Python SDK · pre-recorded URL; Node / JavaScript SDK; cURL · no SDK.
Can I automate Deepgram-style transcription without running it myself?
Yes. If what you want is transcripts rather than the tool itself, Whipscribe does the same job as a hosted API: submit a file or URL, poll a job id, pull the result as txt, json, srt, vtt or docx. $0.008 a minute — about $0.48 an audio hour — bought as credits that never expire. The automation recipes on this site show it wired to Drive folders, Zoom recordings, S3 buckets and no-code platforms.
How is Whipscribe different from Deepgram?
Deepgram is another vendor's product; Whipscribe is a per-minute transcription service. Recordings are transcribed on our own servers and never used for training, and every job returns five formats plus an AI summary, quotes and topics. Every recording starts with a free preview of its opening minutes, and a pack from $4 (500 minutes) transcribes the rest and opens every export.
What does transcription cost if I use Whipscribe instead of Deepgram?
$0.008 a minute — about $0.48 an audio hour — bought as credits that never expire. There is no subscription and no monthly minimum: a 3-hour recording is about $1.44, a thousand-hour archive is about $480 once. Every recording starts with a free preview of its opening minutes, and a pack from $4 (500 minutes) transcribes the rest and opens every export, so you can see what your recording holds before paying anything.
