Two questions: As far as I understand Siri uses Nuance's Dragon Naturally Speaking speech-recognition for actual speech recognition. Is that correct? If that is correct, then what is added value of Siri/Apple? Is it going to be better than Dragon? Did anybody tried this? Does it really understand normal English or English with a little of an accent? There are so many speech recognition products on the market and none of them work well. Meaning they work like 50% or maybe 80% of time - so you just gave up.
