How to create your own program similar to Siri?

You know about Siri on the IPhone 4 & 5 and IPad 3, 4, and mini? Well, I was wondering if you could make your own assistant program like that. Like in Adobe Flash CS5, Game Maker, HTML 5 or some sort of way? I don't know. If you know if it's possible and how to do it, answer this question for a best answer!

YES you can nothings impossible but you can't copy the voice nor the coding they used to make it or else you will get sued or all your hard work is gone adobe did offer a developer kit that worked with android and iOS it was recent like a month ago they gave out away for free limited time offer and the thing with that program was it is unhackable nobody can code your stuff or mess with it i don't know if the program is still up

Of course it is possible, although none of the languages you proposed are good candidates for such a project.

While Apple has never said how much Siri cost them, it's estimated that they spent roughly $200 million for it.

If you intend to embark upon a project of that magnitude, you are definitely asking in the wrong place. You need to hire a team of people with Ph. D level knowledge in computer science, linguistics, etc. Of course, you'll also need patent attorneys, etc. To make sure your project doesn't violate existing patents on voice recognition, artificial intelligence, etc.
