Which one should you pick?
Pick Gladia if
You’re building around voice product developers. Gladia took Whisper and re-engineered it to work in production — sub-300ms streaming latency, code-switching across 100+ languages, diarization and translation in the same stream. For developers building voice products it's a serious Whisper-API upgrade.
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.
