iPhone 4S: Siri is Impressive, But Still a Work in Progress


Apple is bringing speech recognition to the masses with its new iPhone 4S, equipped with an intelligent assistant named Siri. It’s a major differentiator for the new iPhone, setting it apart from its predecessors. I’ve been using speech recognition software for the past 8 years, so I was eager to take this enhanced version of Siri for a spin. Here’s my review.
Siri is not new. It started its life as an experiment funded by DARPA, said to be the largest artificial intelligence project to date. Next, Siri, with the same Nuance speech recognition tech built in that also powers the application I’ve been using for years, Dragon NaturallySpeaking, was first available as a free app on the iPhone in February, 2010. Then Apple bought Siri in April of 2010 and decided to incorporate it into its new iPhone 4S, breaking the old Siri app on other iPhones (unless you want toperform a crude hack).
So now Siri is baked into every iPhone 4S, and not available elsewhere. Siri has come a long way since it was first introduced as a less-accurate and somewhat incomplete iPhone app. Now it’s better integrated into iOS 5, and my immediate impression is that it’s more accurate than it’s ever been. Even in a noisy environment inside a car going 60 miles an hour, it can still understand most of what you’re saying if you hold the iPhone up to your ear. Its speech recognition isn’t perfect, and some of its errors are laughable, but in a quiet environment its accuracy is nearly equal to that of the desktop version of NaturallySpeaking running on extremely powerful processors.
Its integration into the iPhone 4S’s iOS 5 software makes it convenient to use. You press and hold the iPhone 4S’s Home button, and it springs to life, sounding a short beep to signal for you to begin speaking. You can use it in this speakerphone mode, or if the iPhone 4S is turned on, you can simply raise the handset to your ear (a necessity when riding in a noisy vehicle) and the phone’s proximity sensor activates Siri, usuallyprompting you to begin speaking (inexplicably, sometimes it doesn’t respond).
“Only a company with thechutzpah of Apple would have the courage to try something like this. But Siri works just barely well enough for Apple to pull it off, bolstered by the iPhone 4S’s faster processor and better camera.”
That odd non-working tendency must be why Apple is still calling Siri “beta.” The company reassures users that the Siri will be continuously improved, adding that the software learns how you speak as you go and will perform more accurate recognition as it learns your way of speaking. Still, loading beta software into a new piece of iPhone hardware is a thin thread on which to differentiate this new product. Only a company with thechutzpah of Apple would have the courage to try something like this. But Siri works just barely well enough for Apple to pull it off, bolstered by the iPhone 4S’s faster processor and better camera (among what Apple boasts as 197 other incremental improvements), all doing their part to strengthen the lure of this updated iPhone.
Over the 48 hours I’ve been using Siri, it’s hard to tell if it’s actually improving its speech recognition, but as it stands, it’s just good enough to be fun to use. I especially like the way you can almost carry on a conversation with it. For example, you can ask it, “How’s the weather in New York today?” It will answer by showing you the iPhone’s weather app with New York’s data displayed. Then, if you ask it, “Where are the good Italian restaurants there?,” Siri responds by finding 24 Italian restaurants in New York, sorted by rating. It knows you’re still talking about New York. Clever.
