A friend of mine is interested in speaking to his new MB so that it will type letters etc. for him.

Many years ago, I remember that one had to spend days "training" one's computer to recognize a voice and personal speaking habits, even reading off long lists of words.

But I haven't kept up on that technology, so know nothing about it now.

Any ideas of what might be available, the reliability of it? He simply wants to speak to his MB and have it type his words and sentences. Possible now?
