Hehe! I am here!
Unfortunately the answer is no.
Siri (voice control) will only do some predefined tasks with built in Apps (address book, calendar, stock, weather) and some online websites (wikipedia...).
It will also offer dictation where you can type text, in any app.
Howere there is no special API which developer can use to add voice control specific functions to their apps.
(by the way voice control doesn't really work to control music and TV as, by definition there is too much background noise).
