The Google Voice service provides an option to receive text notifications when you get a new voice message as well as calendar events. You can disable both options within the Google Voice dashboard. Once disabled, you must log in to the Google Voice website to view new messages and events. Google voice also provides an option to transcribe your voice messages and have the resulting text-to-speech messages sent directly to your email inbox, if desired.
