Has anyone tried Qt Speech?

[JoeCFD]

I tried this module of 6.9 on Ubuntu 22.04. The sound is not great.

@JoeCFD
I tried it under Ubuntu 22.04 (or might have been 20.04) Qt 5.15 for fun, and it was not great either :)

Hi,

On macOS it's pretty decent.

[JoeCFD]

@SGaist I tried different English selections, German and French. None of them is great. Will try it on Windows.

[SGaist]

Which backend are you using ?

[JoeCFD]

@SGaist I did not select any specifically and the default was applied. Did you select one?

[SGaist]

On macOS it's using the system's speech system. AFAIR, Linux has multiple software that provides that service hence my question.

@SGaist Tried another one: festival, Still very robotic and unnatural. Will try more.

Note that this is outside of Qt's control. The quality of the voice highly depends on what the backend offers.

I tried it a while ago, when I was first starting with Qt...and yeah, doesn't sound so great. The reason why is already explained by SGaist.

I tried a lot of options on Linux (KDE Neon, Fedora), and RHVoice seemed to sound best, but still not quite there, and I'm not sure how are things now, but, if it helps:

Try different voices and voice settings, or look for other options, perhaps new ones exist now.

I'm also interested to see if anyone has suggestions.
