What it does
This project builds on a 2018 research paper. It makes a digital fingerprint of a voice from a short recording, then uses it to read out any text you type. It includes a simple desktop toolbox for trying it.
The author notes the project has aged, that many paid services now sound better, and points to newer open projects for higher quality.
Who it's for
Students and researchers interested in how speech synthesis works.
