Which one should you pick?
Pick Deepgram if
You’re building around enterprise voice infrastructure. Deepgram is what large companies use when they're embedding voice into a product and need someone on the other end of an SLA. Accuracy is competitive with AssemblyAI and latency is excellent for real-time use cases.
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.
