Found this tip at another site: I find it useful.
Have too much gear and no time to read all the Owner’s manuals?
I will use the text to speech processor built into all recent versions of Adobe Acrobat - Open up a new PDF User manual and let the computer read it out loud to me. I may use my 900MHz wireless headphones and be mobile around the house.
If I’m doing other tasks, (like cleaning, laundry, bachelor stuff) In this manner I can grasp functional concepts of the new gear much faster, then - when I’m finally able to sit down and play with it later - i have a head start as I use “Find text” in Acrobat to fine tune my knowledge and master the unit in question.
FWIW - the Mac with OSX (and any IOS5 device - iPhone, Ipad, Ipod Touch) can read aloud any text you highlight on the screen , and read entire documents with a much clearer voice I can understand 90% of the time I do that all the time - rather like having a “books on tape” version of my all my Owners manuals.
Prior to my iPhone, i would make MP3 recordings of these - so i could listen on headphones at work at my day gig.
But the recent IOS5 has a method of enabling text to speech right on the device.
