I'mI was having the same problemissue with S-Voice on my Samsung Galaxy S4 all of a sudden. Can anyone helpA Samsung support tech helped me figure it out by telling me to start the phone in Safe Mode to see if S-Voice worked that way. He said if it did, please?it was most likely a 3rd party app. Turns out he was right. I deleted Music Download Paradise Pro, which was the most recent app I had downloaded and S-Voice has worked since then.
