Speechify vs Vapi
Vapi is a flexible, API-driven way to build voice agents — but its $0.05/min is an orchestration fee; you add STT, LLM, TTS, and telephony on top (~$0.10–0.20/min all-in). Speechify is one all-in rate from $0.07/min with LLM included, plus a workflow editor, tool calling, evals, and governance, and 60 free minutes a month.

The verdict
Vapi is a strong choice for engineering-heavy teams that want to own every layer and have the resources to build and maintain custom integrations, evals, and governance. Speechify is the better fit when the priority is shipping production agents faster on an all-in rate, with the compliance surface and integrations enterprise buyers require.
