Where voice AI spend leaks
Costs buyers often miss
- Platform fees or seats that must be paid before usage creates value
- Pass-through STT, realtime model, TTS, telephony, and orchestration bills that are hard to forecast
- Credit or character pricing that hides the cost of long calls and long-form audio
- Manual QA, compliance review, and call summaries that only happen after the expensive mistake
How PyAI helps you prove the switch
PyAI keeps testing cheap and migration practical: free credits, OpenAI-compatible surfaces where supported, transparent minute pricing, and production add-ons for QA, compliance, summaries, and grounding.
