I play around with Speaktoit myself. I like it alot due to its highly customizable features. Personally much better than vlingo and iris ans etc.
Virtual assistants have been around since forever. Apple didn't invent the idea, nor did they invent SIRI. Google SIRI and you'll come across the top 10 developer iPhone apps... from 2010. All apple did was buy the app from the dev, remove it from Appstore, preload it in their 4s, and imply through ads that they made a innovative app. There is no innovation in closed source systems. Just "buyouts".
