Read out/aloud function in read mode in Firefox

Hi,

I’m looking for to activate the read-out function of Mozilla Firefox in the read-view of a website. As said on the Firefox website, this functionality is only available when Speec synthesis is installed on Windows.

Is there any possibility to activate this on Manjaro Linux? My Firefox browser is version 93.0 64 bit.
Or is there any other alternative opensource read-out addon available which is working with manjaro?

Regards!

Installation of package “speech-dispatcher” and a restart activated the functionality also in Manjaro.
But the voice preinstalled are very bad. Or is it the speech engine itself?

Is there a better one anybody can suggest?

Just putting this here.
