What we know about Speechify API
Speechify API is a text-to-speech apis platform: developer platform spun out of the Speechify brand: transparent tiered pricing ($10-$499/mo plus per-1M overage), streaming-native Simba 3.2, and a bundled voice-agents product with flat per-minute rates. This profile tracks every Speechify API fact we have verified, each linked to a primary source and dated.
On pricing, Speechify API starts at $10 per month for its entry tier. That is the sticker rate: real production cost usually runs higher once you add a language model, a voice provider, and telephony minutes.
On capabilities, Speechify API covers streaming audio output, instant voice cloning, professional voice cloning, emotion / style controls, ssml support, and word-level timestamps. Each of those is verified against Speechify API's own docs or dashboard, not marketing copy.
Speechify API ranks the 1st-cheapest flagship rate of the 16 text-to-speech tools we track, but only 17th of 16 for languages, so where it lands for you depends on which of those matters more.
In total we track 19 verified facts for Speechify API today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the Speechify API fact sheet below.

STT in this stack
Text-to-speech is half of a voice pipeline: the other half is the speech-to-text that listens. Compare transcription engines on accuracy, streaming latency, and per-minute price: Deepgram, AssemblyAI, GPT-4o Transcribe, or the full speech-to-text comparison →
Voice agents in this stack
The engine is one layer: a voice agent speaks through its text-to-speech engine, but orchestration, telephony, and turn-taking come from the agent platform.
