In this sentence, 'eisiau' appears to be pronounced with an 's', whereas in previous sentences and when pronounced separately it has an 'sh' sound. Are both correct and a matter of preference, or is it TTS?
it should be a "Sh" sound. Any "Si" in welsh is a "Sh" shound e.g the name "Osian" is pronounced "Oshan"
I noticed that, too. At least when you click on the individual word, it pronounces it correctly.
