Move over, Siri

摘要

The idea of artificially intelligent personal assistants-digital secretaries, made of software, that take dictation, manage contacts, book lunches and arrange transport-has been around for many years. But truly successful examples have proved as elusive as flying cars. Perhaps the best known example is Siri, the personal assistant built into Apple's iPhones and iPads, which can understand complex spoken sentences such as "Please reschedule tomorrow afternoon's meeting from 4pm to 3pm". As clever as this is, however, Siri still feels more like a technology demo than a really useful assistant.
