I have an iPhone 5s running iOS 7.0.3 and recently noticed that Siri's voice is the same as it was on on iOS 6. I called Apple regarding the issue and they advised me to restore my phone - which I did. It just finished restoring and the new voice still is nowhere to be found. Does anyone know what the issue is? Hopefully I'm missing something simple. I should note that this is a replacement iPhone 5s and the new, high-quality voice was present on my old 5s.
