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 Sonix if
You’re building around business team workflows. Sonix is the boringly competent middle of the transcription market — pay-per-hour at $10 or Premium at $5/hr plus a $22/user/mo platform fee, 53+ languages, SOC 2 and HIPAA-ready. The hybrid pricing model is confusing on purpose, and the per-hour AI rate is higher than running raw Whisper.
