First off: i don't know if this already exists, I looked for it on iOS 6 under accessibility but didn't find anything.
So.. I was thinking, wouldn't it be great if - using Siri/Dictate/Speech-recognition technology - your phone could convert your incoming voicemails to text? That way, whenever you're in a situation where you cannot listen to your voicemail, your phone can just send you a message with the spoken message converted to text, so that you can just read it on your phone (or tablet/mac with iMessage). Feels like this should be possible, right? Or is it not possible/difficult for the carriers to support this functionality?
Of course, Voicemail is something we use less frequently nowadays, but still; my dad still leaves me a Voicemail instead of texting me.
