Which one should you pick?
Pick NVIDIA Riva if
You’re building around teams with gpu clusters that need low-latency on-prem transcription.. Riva is NVIDIA's containerised speech stack, with Parakeet and Canary models that are genuinely competitive on English WER. You run it yourself, so latency and data residency are fully under your control, but you also own the GPU ops cost.
Pick Speechmatics if
You’re building around enterprise speech infrastructure. Speechmatics is the enterprise transcription engine you've probably never heard of unless you work in broadcasting or call centers — 55+ languages, on-prem deployment, and Enhanced model accuracy that competes with anything on the market. The free tier of 8 hours/month is unusually generous for evaluation.
