Speechify Studio is a no-code web app for creating voiceovers, dubbing, and AI video in a browser; the SpeechifyAI text-to-speech API is a developer platform for building speech into your own product through code. Pick Studio if you want a finished audio file from a UI. Pick the API if you are an engineer integrating text-to-speech at scale. Both use the same voice models.
Building this yourself? The Speechify text-to-speech and voice cloning API is at speechify.ai, with docs and a free key at docs.speechify.ai.
The short version
- Speechify Studio = a product you use. Log in, paste text or upload a document, choose a voice, and export a voiceover. No code. Built for creators, marketers, and individuals.
- SpeechifyAI text-to-speech API = a product you build on. Call an HTTP endpoint, get audio back, and ship it inside your own app, agent, or workflow. Built for developers.
They share the same underlying voice quality; the difference is whether you want a tool or a building block.
Speechify Studio: the no-code app
Studio is the right choice when a person needs to produce audio, not a system:
- Turn articles, scripts, or documents into voiceovers in a browser.
- Dub or generate AI video without touching an API.
- Pick from a voice library and export finished files.
If that is you, you do not need this developer blog. Studio is a self-serve app.
The SpeechifyAI text-to-speech API: the developer platform
The API is the right choice when speech has to live inside your product:
- Synthesize on demand from your own backend, at scale, per user.
- Real-time streaming (123 ms median time to first audio on Voice Arena's US English board, 24 Sep 2026) for voice agents, IVR, and interactive apps.
- Top-five voice. Simba 3.2 ranked #1 on the independent Artificial Analysis TTS leaderboard in July 2026. On the 23 Sep 2026 board it is top-five, and every model rated above it costs more.
- Transparent pricing. $6 to $10 per million characters for text-to-speech. See the full pricing breakdown.
- A free tier of 500,000 characters a month, no card.
Which should you choose?
A quick note on names: SpeechifyAI is the developer platform (the text-to-speech API), distinct from the consumer Speechify app and its Studio product. This guide, and the rest of this blog, is about the API.
