A $0.15/hour API can end up costing more than a $0.60/hour one once channel billing, add-on features (diarization, redaction, entity detection), retries, and human correction time are factored in. The true metric is cost per accepted transcript measured on your own audio. Key providers compared include AssemblyAI, Google Dynamic Batch, OpenAI gpt-4o-mini-transcribe, ElevenLabs, Deepgram, and AWS. Real-time transcription requires a separate scorecard covering stable partials, finalization delay, and endpointing — not just time-to-first-text. Accuracy benchmarks should use production-like audio, not public datasets. The recommended approach is a 7-day evaluation followed by a routing policy that assigns different providers to different workload types (live calls, multilingual meetings, batch archives). ## Full article daily.dev links to this article rather than hosting it.
