Use piper for TTS rendering

[Sati]

There's a Narration button (the one with a headphones icon) on the navbar (which is available by hovering or tapping on the footer area).

Note that if the book has embedded audio (media overlays), the Narration button would show controls for the embedded media, and TTS would not be available in that case.

Alternatively you can select some text and choose Speak from here from the selection menu. Though you still need to use the Narration button if you want to stop the speech output.

I've installed pied and speech-dispatcher seems to be working with spd-say - even though there is this error:

When I run narration, I get a TTS error:

Any idea how to fix this?

[John Factotum]

It would print the error code and message to the console. It's probably throwing at the 300 MODULE ERROR message.

Here are the issues stated when running on terminal.

Catalogs don't work for me too.
