Deepgram

Deepgram is a developer-first speech AI platform that turns spoken audio into accurate, structured text in real time. Its Nova-3 and Flux models transcribe live calls, meetings and media streams with low latency, in 60+ languages, and add speaker diarisation, smart formatting, redaction and entity detection on top of the raw transcript.

What sets it apart is the breadth around transcription: the same platform covers pre-recorded files, live streaming and full voice agents that listen, reason and speak back, so teams can build contact-centre analytics, meeting copilots and conversational products without stitching together several vendors. Billing is per second of audio, with no rounding up to the next minute.

It is built for developers and product teams shipping voice features at scale — not for anyone who just wants to upload a file and get a transcript back. If you can work with an API, Deepgram is one of the fastest, most complete speech stacks available.

Pros

• Real-time streaming transcription with low latency, in 60+ languages.
• Diarisation, redaction, entity detection and smart formatting built into the API.
• Voice-agent tooling plus pre-recorded transcription on one platform, billed per second.

Watch out for

• Accuracy depends on audio quality and model choice — benchmark on your own calls before committing.
• An API product for developers; there is no simple upload-and-transcribe app.
• Add-on features such as diarisation and redaction are billed on top of the base transcription rate.

Best for

Development teams building live transcription, call analytics or voice agents — especially contact centres, meeting tools and media workflows that need low-latency streaming at scale. Who should skip it: anyone who wants a no-code transcription app, or only needs the occasional one-off transcript.

Pricing

Deepgram is pay-as-you-go with a $200 free credit for new users (no credit card required, and the credit does not expire). Speech-to-text starts at $0.0077 per minute for Nova-3 and Flux monolingual models, and Growth plans from $4,000 a year save up to 20%. Verify current rates on the official pricing page.

Example

A support team streams a live customer call to Deepgram’s streaming API and receives a running transcript with speaker labels as the conversation happens; redaction masks card numbers as they are spoken, and when the call ends the transcript is summarised into a ticket note — all from the same API, billed per second of audio processed.
