A few days ago, I replaced my iPhone 5 with a new iPhone 5 because of some very strange issues causing the battery to drain very fast. They gave me the new iPhone 5 running iOS 6.1.4, so when I got home, I upgraded it to the latest version of iOS - iOS 7.1. Now, what's weird is that there are no natural sounding voices for Siri, it almost sounds worse than in iOS 6. I choose any voice dialect of English I want and I still have the same result, it is never any different. I've even tried the other languages and the voice gender for Siri, nothing has Apple's new natural sound to it. If it is useful to know, I upgraded the phone by connecting it to my computer. I chose to just upgrade it rather than restore and upgrade, and I set it up as a new phone. Does anyone have any suggestions?
