pesto! TTS logoThe name "pesto" is coming from the Greek phrase "πες το", which means "say it": pesto TTS is a text-to-speech system that gives you voice from written texts. Why a sauce name for a text-to-speech? Probably because you can cook your applications with pesto TTS!

pesto TTS is the text-to-speech runtimes of PhonAesthesia Language Suite, a collection of speech tools and resources that is being developed by e-rhetor for more than 10 years. It is flexible enough to host almost any kind of linguistic resources and voices, from small-footprint to large scale, performing robotic to natural and expressive speech synthesis.

Version 2 is coming!

Version 2 is now getting pesto TTS off the ground by introducing fast custom expressive voice deployment within a few days, bridge to Flite synthesis engine and more. Available for Windows, Linux and Android.
