Digital secretary Siri was, and still is, the headline feature of the iPhone 4S. It owes some of its allure to the vast processing power of Apple's servers that run a remarkably sophisticated voice recognition software licensed from Nuance, a Burlington, Massachusetts-based provider of arguably the best voice technology money can buy.
According to Nuance’s marketing honcho, you can bet on Siri to improve over time. Upcoming developments in personal assistants will enable new stuff, such as more accurate voice recognition and personalization. So yeah, eventually you'll be able to ask Siri “Is my favourite movie on tonight?”
