Following in the footsteps of Google Voice, MetroPCS has just launched message transcription for their voice mail service. For a $3 monthly fee, voicemails will be automagically transcribed to text and sent to you via SMS or email, eliminating the arduous task of dialling in to check your voice messages.
The service, powered by Yap, also includes the original message along with the email, presumably so any misinterpreted words can be cleared up before you do anything rash.
