Best Text to Speech API Tools: Our Top Picks for 2026
A text to speech API lets your own app send a script and get spoken audio back. Zoice is our top pick for developers who want to try voices in a playground before writing code: the Zoice developer platform at dev.zoice.com has a Text to Speech page with a live playground and a documented endpoint.
This guide compares Zoice with ElevenLabs, Google Cloud Text to Speech, Amazon Polly, Microsoft Azure Speech, Deepgram and Murf. Each entry covers what the API offers according to its own site, who it suits, pros, cons, the G2 rating where one exists and how pricing works, with a screenshot of each.
What Is a Text to Speech API?
A text to speech API is a web endpoint that turns text into audio. Your code sends the words and the voice you want, and the service returns speech you can play, save or stream inside your product.
Developers use one to add narration to apps, read content aloud, voice an assistant or produce audio in bulk without recording sessions. The main differences between providers are how you pick voices, what the request looks like, which cloud they live in and whether you can test voices before you build.
