If you have been looking for a free speech synthesizer for Linux, festival is one of the reliable solutions. Festival is a framework that helps building a speech synthesis system. It helps users convert normal text into speech outputs. This software can be of great help particularly for people having speech disabilities. This project focuses on showcasing how to use the same on the UDOO platform. For more details about festival visit their website here.
