The decision in context

Deepgram is positioned as speech recognition models with separate speech generation and managed voice-agent APIs. Trillet AI is positioned as a voice platform with distinct receptionist, agency and managed enterprise products. Start by deciding who owns the missing layers, then inspect the documented differences below.

STT and Full Platforms are different product categories. An underlying engine or framework is not a complete substitute for a deployed agent workflow.

12 jointly documented catalog fields. This measures evidence coverage, not equivalent quality or an overall winner.
