I want to be able to read out aloud PDFs in Ubuntu. I currently use the Okular PDF reader. After installing Jovie, I was able to read out aloud my PDFs in Okular. However, I find the the speech quality of the current synthesis engine (espeech) to be terrible, and nowhere close to the quality of text to speech engine on my android phone.
I installed that synthesis engine of android (libttspico-utils). Now I'm stuck at trying to make Jovie aware of libttspico-utils. The Jovie handbook (section A.2) says "It (Jovie) also works with any synthesis engine that can be run from a command in a Konsole.", but doesn't explain how to do this -- which is my question here. I know that libttspico-utils can be invoked over commandline.
