Speechify vs Deepgram
Deepgram's Voice Agent API bundles STT, LLM, and TTS at $0.075/min — strong, low-level infrastructure. Speechify is a complete platform at a lower all-in rate (from $0.07/min, LLM included), billed on talk time rather than connection time, with deterministic workflows, tool calling, telephony, and compliance built in — and 60 free minutes a month.

The verdict
Deepgram is an excellent choice if you want low-level speech infrastructure and intend to build the agent platform — orchestration, telephony, integrations, evals — yourself. Speechify is the better fit when you want that platform out of the box at a lower all-in rate, billed on talk time rather than connection time.
