Techi types come hither

[heartofGold]

A friend would like to dictate his memoirs for me to type.  I have got as far as thinking he buys a digital dictaphone and then saves to usb which he then sends to me as he progresses but that's the limit of my knowledge.  Is there a way he can get the dictation to me electronically with any different equipment/app/software etc to make things easier?  Thanks if anyone knows any more.

Using Google docs you can simply plug in a microphone and speak into it for it to type.
