Text to speech (TTS): the complete guide for creators
What text to speech is, how modern TTS voices got so good, and how to turn your writing into audio people actually want to hear.
Text to speech (TTS) converts written words into spoken audio. The technology has quietly crossed a line: modern TTS no longer sounds like a robot reading a phone menu — it sounds like a person.
How TTS works (briefly)
Early text to speech TTS systems stitched together recorded sound fragments. Today's neural models generate speech from scratch, predicting natural rhythm, emphasis, and intonation. That's why current voices handle pauses, questions, and emotion so much better.
Natural vs. expressive voices
Two tiers cover most needs:
- Natural — an even, warm narrator. Ideal for articles and tutorials where the writing is the star.
- Expressive — steerable tone for stories, launches, and opinion pieces, where the delivery should carry feeling.
We go deeper in natural vs. expressive voices.
What you can do with it
- Add a "listen" option to every blog post (see what a blog reader is).
- Turn newsletters and docs into audio.
- Make content accessible to readers who can't or don't want to read on screen.
