LiveKit is positioned as realtime agent infrastructure for teams that own the application and model stack. Speechify is positioned as a developer TTS API under SpeechifyAI, distinct from the consumer reading subscription. Start by deciding who owns the missing layers, then inspect the documented differences below.
Developer Frameworks and Voice Engines are different product categories. An underlying engine or framework is not a complete substitute for a deployed agent workflow.
9 jointly documented catalog fields. This measures evidence coverage, not equivalent quality or an overall winner.
Test opening hours, booking conflicts and an unanswered transfer.

Paid monthly subscription includes USD usage balance consumed by character-priced synthesis. Agent quote separate.
Agent session component only; not complete call cost.
Captured pricing summary does not provide complete per-character rate/balance table; full pricing evidence requested. Do not use consumer reader plans.
