You can offload both 1 and 2 to third party services - one of the major ones with a properly public API that officially supports (and thus charges for high volume use) use by other parties is Microsoft's Project Oxford [0].

You could also use some of the Google APIs, but those are more-or-less unsupported, and subject to change as Google needs to change them.

From there, it's a matter of transforming intent into action.

It's entirely possible to do, but you'll have a lot of learning to do to implement it. One place you might start looking is at the Microsoft Python blog [1].

As much as possible, this.

If you, singular, are building Siri v2, you need to do as little as possible yourself. Find an OSS library / tool that does the thing you want, use Caffe/Theano/etc. instead of rolling your own code, use a commercial package if you absolutely have to. Concentrate on the "hard" parts, understanding and translating language to action. Build that part, and glue on all the other stuff. After you get a working thing you can peel off the layers and replace them with something of your own, maybe, or more likely something better will come out by that time and you can plug it in with minimal effort.
