Voicemail to Text

Check out this video on voicemail to text. This technology might be useful as we all know how annoying it is to deal with voicemail. Only issue is the accuracy of the translation engine!
Google is only one of many companies trying to advance this technology. I suspect that in very short order it will be a standard option on business IPPBX's and Hosted Telephone Systems.
What do you think useful or annoying?
