I really enjoyed Joe Frank's voice for the ships computer. If they can get him back it will all be worthwhile IMHO no matter how else it turns out.
I know Google Voice has provided this for some time. I know you can use 3rd party service YouMail. You're missing the point. Apple is pushing for user privacy. This means that the voicemail would be transcribed by Siri on *your* phone. Nobody else would have access to it to store it or scrape it or learn from it. Not in "the cloud".
What the hell are you talking about? Siri can't do jack-diddly without the internets. Won't even set a fricking timer or tell me what time it is. Every single thing Siri does is reported to and processed by the Apple mothership.
Anything cut to length will be too short.
