There is a video interview with the CEO, here. In the interview he says that all of the transcription is done manually by a person in a call center in Egypt. I've been using it for a few weeks and it's accuracy is unbelievable. I was wondering how they did it. Now I know. Not sure how well this business model will scale though. I'd imagine there are people in government jobs (often blackberry users) that are no too keen on having their messages routed to Egypt ... or anywhere outside their country of origin.
