@philn No, IIUC from what Joannie says here, Orca relies on speech-dispatcher, I assume it has a Spiel plugin? I found plugins for Festival and Flite on Fedora. I tried the Flite one, which gave me barely better result than espeak. I'm trying to understand the state of TTS in general, but finding information isn't easy. https://gitlab.gnome.org/GNOME/orca/-/issues/378
