From accents to background noise, there are plenty of obstacles that can throw off Siri's speech recognition powers. But understanding what you've said is only half the battle -- next Siri needs to decode what you mean.
Despite the sophistication of Apple's snarky robot butler, turning Siri into a reliable, genuinely useful assistant is going to take time. In the video above you'll learn how two fields of study -- automatic speech recognition and natural language understanding -- must work in harmony to create a Siri we'll actually use, instead of just swear at.
Hope springs eternal, however! Apple is rumoured to have acquired speech-recognition firm Novauris, possibly in a bid to tune up Siri's ability to hear us correctly. Meanwhile Microsoft is throwing its hat into the ring, revealing Cortana as a new Siri rival.
