Speeches are what kind of text-based media

It has been fascinating to watch the evolution of media types over the last several years. We started off with a realtime speech communication mode - a phone call - and an asynchronous text-based communication mode - email. In addition, there was voicemail as the asynchronous messaging mechanism, but it was tightly contained within the speech box. You could only access  voicemail from your phone - whether you left a message or wanted to listen to a message. Over time, this has changed in some ways - we now have unified messaging where you can access your voicemail from your email, but you still have to listen to them - as a wav file or mp3, maybe, but you still listen to your messages. Unity provides the ability to pick up an voicemail message being recorded and continue as a live call - thus escalating an async communication to a synchronous voice communication session, but once again, this is strictly within the voice context
