Speechmatics is positioned as recognition APIs with cloud and private-deployment choices for transcription-heavy products. Start by deciding who owns the missing layers, then inspect the documented differences below.
Voice Engines and STT are different product categories. An underlying engine or framework is not a complete substitute for a deployed agent workflow.
8 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.
Credit billing: one credit equals $1; usage measured by product hours/seconds. This does not mean a character-priced TTS rate or flat agent minute rate.
Captured pricing summary does not provide complete per-character rate/balance table; full pricing evidence requested. Do not use consumer reader plans.
Price page exposes a Pro 0.129 figure without a clear unit in captured content; exact model rate and enterprise commitment require confirmation.
Enterprise agent pricing excluded from this ladder.
Billing currency versus usage unit kept distinct.
Included USD usage balance and per-character usage, not all-in agent minutes.
