Very good *if* enabling a proper voice. Select "Edit" in front on "Voices" and select e.g. English => Google Translate English, then "Back to options", and (in Firefox) grant required browser permissions to access the voice.

By default, the voice sounds much like the regretted physicist S. Hawking (and the app becomes worth 1 star).

Four stars because it's not quite as natural-sounding (intonations etc..) as say Google Android Assistant on "read aloud" command, using their browser.
