AI voice API pricing comparison
Compare selected voice-session and transcription prices while keeping unlike billing units and input/output components separate.
Direct answer
The decision in brief
Match the job and billing unit before comparing prices. Realtime sessions, speech generation and transcription can charge by audio token, text token or minute, so a single cheapest-price ranking would give the wrong answer.
