Deepgram
A commercial speech API built for fast, accurate transcription at scale, including real-time.
Deepgram is a hosted speech-to-text platform aimed at production workloads. It does accurate batch transcription and genuine low-latency streaming, with features like diarisation and word-level timestamps built in.
It is the pragmatic choice when transcription is core to a product and you would rather buy reliability and speed than operate model infrastructure.
Where it fits
Best when transcription is on the critical path (real-time or high-volume) and a managed, low-latency API is worth paying for.
Where it does not fit
Wrong fit when audio cannot leave your environment, or when occasional transcription does not justify a metered API.
