  Text to Speech? (DECtalk)? 
 The Question is:
 
Do you have a sound card which can generate voice messages from ASCII texts?
 
 
 The Answer is:
 
  This would typically be a DECtalk or similar device, and typically
  an off-board device -- effectively a text-to-speech printer -- is
  the easiest approach as it avoids the need for any host device
  drivers.  Acquisition of used DECtalk device(s) (DTC01, DTC03) would
  be an obvious option.
