Siri Auto read text msgs?

[Nekcik]

After watching this video the one key factor in buying my iphone 4S was the ability for Siri to auto read the text without having to activate it using the home button. in this video you can clearly see she is not touching the phone and the voice automatically reads out the text (see 1:00)
Is there a setting I am missing for this to work? I can't get her to read it by herself without having to hit the home button and asking siri to read my text msgs.
Thanks for the help in advance!

There's a voice over setting in the accessibility options, but it reads everything, not just texts, since it's intended for those with vision problems.

after what you typed and watching the video again I realized she is reading braille and struggles a bit reaching for her iphone because she is blind.

Was really hoping for a way for siri to read them on her own. I work a dirty job and I hate having to go wash my hands all the time when a text comes in just to see if it's important.
