A clear communications "channel", with the message/words clearly articulated and received and understood by an knowledgeable undistracted individual with flawless cognitive abilities is certainly the best way to communicate. However, this is the exception rather than the rule.
Thus written and verified messages are a substitute.

A trained speaker may communicate even more quickly. Sending is not the challenge, the choice of reception is. If we insist upon writing down the spoken word then we slow things down considerably, but the same is true of CW. Recording the spoken words would mean that a 100 word message would be transmitted *and* received in less than 1 minute. Speech recognition is one means by which the speed of verbal transmission and written reception may be increased but accuracy and speed (especially with the addition of noise and different speakers) has proved challenging. Improving the written capture of speech modes: http://www.rci.rutgers.edu/~leed/Notetaking.htm The advantage of CW is that once the message, originally verbal or written/printed/E-mail has been manually digitized (keyboard CW) and sent it may be electronically decoded and printed somewhat quickly and accurately. The same is true of other keyboard modes Moving text files is an even more efficient mode if one is not engaged in a semi-realtime keyboard to keyboard conversation. 73, doc KD4E Need a Digital mode QSO?
