It works in much the same way that Siri transcribes your voice commands, but it's unclear if the system would require carrier support. Currently, Apple's visual voicemail service (which can also back up messages to iCloud) only works with select operators. It's also not clear if it'd be free, as certain carriers charge extra for that. Nevertheless, it sounds like a good idea -- as BI pointed out, lots of folks aren't fond of voicemail, but the less tech-inclined still prefer to leave them. Employees of the company are reportedly testing the service, and if it's reliable enough, it'll be launch next year along with iOS 10. As always, however, take such rumors with a large chaser of skepticism.
