  Hume AI offers seven plans (Free, Starter, Creator, Pro, Scale, Business, Enterprise) for
  TTS and EVI usage, plus pay-as-you-go pricing for Expression Measurement. Each plan bundles
  monthly TTS character allowances and EVI minutes; overage rates fall as tier rises.
notes: Reconciled from Hume's public pricing page (May 2026). Expression Measurement is pay-as-you-go.
