Bob, thanks for the info.
It is not a product I have ever used. I have a speech recognition software that turns speech into text - and will translate an .mp3 of my voice into text - just the opposite of what the original poster requested.
By the way, I really would not trust Norton - it's really bad.
You might consider Avast! - it's free and excellent or try a system check with Trend Housecall - it works online and is excellent as well.
