just got my s4 yesterday and I love it so far.
I have been playing with the svoice command feature and for some reason it sounds like a robot now vs the way it started out. I have it set in the setting to use the uk voice.
so I went to settings> language and input> voice to speech> settings for galaxy s> languages and the uk is ch3cked and downloaded as well as checked in Samsung text to speech. Still robot voice.
I have shut down and restarted via restart.
help appreciated! Thank you.
