How Speechify compares
Honest, side-by-side comparisons against the other voice-agent platforms.
vs ElevenLabs
ElevenLabs Conversational AI is a voice-first agent layer built on the company's well-known TTS. Speechify is all-in — LLM, speech-to-text, and text-to-speech in one per-minute rate (from $0.07/min, LLM included) with no passthrough and no token math — plus deterministic workflows, tool calling, evals, and enterprise governance, and 60 free minutes a month.
Comparevs 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.
Comparevs Retell
Retell gives developers low-latency voice infrastructure with itemized pricing — voice infra at $0.055/min plus TTS, LLM, and telephony add up to ~$0.11/min typical. Speechify rolls it into one all-in rate from $0.07/min with LLM included, plus deterministic workflows, tool calling + webhooks, and governance, and 60 free minutes a month.
Comparevs Bland
Bland is known for high-volume outbound with a clean all-in number ($0.11–0.14/min) — but the lower rate sits behind a $299–499/mo platform fee. Speechify is all-in from $0.07/min with no platform surcharge, and adds inbound voice and a web widget on one brain, plus deterministic workflows and tool calling — and 60 free minutes a month.
Comparevs 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.
Comparevs Cartesia
Cartesia (Line) is ultra-low-latency voice infrastructure with a $0.06/min headline — but telephony adds $0.014/min and the "LLM included" is a limited-time promo. Speechify is all-in from $0.07/min with LLM included permanently, plus a full workflow, integrations, and compliance platform, and 60 free minutes a month with commercial use.
Comparevs Synthflow
Synthflow is a no-code voice-agent builder; real-world setups land $0.15–0.24/min once you add the voice engine ($0.09/min), LLM, and telephony. Speechify is all-in from $0.07/min with LLM included — roughly half the cost — plus deterministic workflows, tool calling, evals, and enterprise governance, and 60 free minutes a month.
Comparevs Hume
Hume's EVI is an expressive, empathic speech-to-speech model priced $0.04–0.07/min — but that excludes the LLM (billed separately by your provider) and the lowest rates need a large plan. Speechify is truly all-in from $0.07/min with the LLM included, plus deterministic workflows, tool calling, and compliance — and 60 free minutes a month versus Hume's 5.
