SpeechifyAI vs Deepgram

Deepgram's Voice Agent API bundles STT, LLM, and TTS at $0.075/min: strong, low-level infrastructure. SpeechifyAI is a complete platform on one all-in rate with the LLM included, billed on talk time rather than connection time, with deterministic workflows, tool calling, telephony, and compliance built in. Pricing is quoted per contract.

SpeechifyAI vs Deepgram, in plain English

Skip the integration quarter

Deepgram is excellent at low-level speech infrastructure. The Voice Agent API at $0.075 a minute bundles STT, LLM orchestration, and TTS, with bring-your-own models lowering the rate further. The implicit cost is the work between that infrastructure and a real production agent: telephony, evals, integrations, a workflow editor, and compliance plumbing, which adds up to a quarter or two of engineering for a small team. SpeechifyAI ships that production layer at one all-in rate, billed on talk time so the integration work does not show up on the team's roadmap.

Pay only when the call is alive

Deepgram bills on websocket-open time, so the seconds when nobody is talking count against the rate. SpeechifyAI bills per second of talk time, so hold music, transfer waits, and the long silences while a caller looks something up stay free of charge, which makes the bill noticeably lower on agents that handle escalations or genuine pauses. Tool calling, webhooks, the workflow editor, and SOC 2 Type II are first-class on every plan instead of primitives you assemble on top of the infrastructure.

The verdict

SpeechifyAI ships a complete production voice-agent platform on one all-in rate, billed on talk time instead of websocket-open time, with the LLM, deterministic workflows, tool calling, telephony, and SOC 2 Type II compliance already included.
