1. Siri works. Voice recognition has been the next big thing for 15 – 20 years.  We still have these frustrating experiences when we call into check the balance of our bank account and have to shout in the phone 5 times in a row, because the application doesn’t recognize us.  Siri is the best voice rec app ever — and it’s still in “beta.”

2. Siri has personality. Not only does Siri accurately recognize our voices but it has a personality to boot.  It’s that personality which makes the app addictive because we start to feel over time that we truly have a personal assistant who is our friend.

3. Siri is hard to copy. For anyone who doesn’t understand voice applications, it’s easy to think that Siri will be easy to copy. It won’t.  There are 2 parts to making a successful voice app: the voice rec technology which has improved a lot but is basically a commodity and the app itself, which is a combination of art and artificial intelligence.  It’s that 2nd part that’s so tough to replicate and that’s why Apple bought Siri last year.  It’s true Google has experience in the voice rec space and doing some simple voice apps but they do not have the personality and AI of Siri and that will be very difficult to copy — especially for a company that doesn’t sit at the intersection of the humanities and technology.

4. Siri helps own the customer experience for Apple. Dan Frommer and others have been talking about this for a long time.  Siri is a new interface for customers wanting to get information.  It used to be text-based input to their desktops.  Then, it was thumbing it in to their mobile devices. Now, Apple is attempting to make it voice-based.  They previously were attempting to Balkanize your data needs by training for you to do specialist searches for the information within apps on your iPhone.  Now, they’re training you to rely for doing any task by leaning on Siri to do it for you.  At the moment, most of us still rely on Google for getting at the info we want.  But Siri has a foot in the door and it’s trusting that it will win your confidence over time to do basic info gathering.  Siri can be potentially leveraged in other devices that Apple ships in the future like TV to become the primary way you interface with info you need.

5. Siri will vastly improve in the next 2 years based on all the data it’s amassing. This game is about where the puck is going, not where it is today.  Many people only look at Siri as the application as it works today.  Yet, the biggest advantage over any other voice application out there today, and the apps still to be developed, is the massive data Siri is now and will continue to collect in the next 2 years.  We know after the first weekend alone, there were 4 million Siri-enabled devices out there probably collecting 1 – 2 utterances a day worth of data — all being stored in Apple’s massive North Carolina data center.  All that data will allow Siri to get better and better.  Think Siri has awesomely funny answers to your crazy questions now? Just wait two years.  She’ll be even more your friend then, knowing you perhaps better that you know yourself in some situations.
