On a Macintosh G3, system 8.6, with Mathematica Version 4.0, a 
perusal of the output from:

?System`*

reveals 3 interesting undocumented symbols:

SpeakTextPacket
CurrentlySpeakingPacket
SetSpeechParametersPacket

After much trial and error all I succeeded in doing was the following:

  (* Example of telling the front end to create a cell with text in 
it, selecting it and then speaking, but only saying the "In[]". The 
"CurrentlySpeakingPacket"
is clearly missing something, but if this line is not included the 
kernel will not terminate without extreme prejudice.  *)

FrontEndExecute[FrontEnd`NotebookWrite[FrontEnd`SelectedNotebook[ 
],"Houston we have a problem."]];
SelectionMove[SelectedNotebook[],All,Cell];
FrontEndExecute["CurrentlySpeakingPacket"]
FrontEndExecute["SpeakTextPacket"]

I was hoping after writing some text to a cell, and selecting it, 
that I could mimic the effect of inputting Control-V from the 
keyboard. This is getting close to working, it reads back the In[]. 
Any suggestions on how to improve upon this?
