I've been following up from the Jailbreaking community on new updates found in the iOS 5 builds. As you know the Apple Jailbreaking community is filled with developers and technicians, so this is why I have been keeping up with them.
Apple has teamed up with Nuance, the well known company that enhances Speech technologies. @ChronicWire uploaded screen shots of the Nuance integration which you can find below. As you can see it gives you advanced options to choose as well as other features that will be useful such as Emoji keyboard to be everywhere, Mic on space key which lets users choose the option of enabling speech to text right on your keyboard.
