It is not easy to understand your posting. "Filler words" in terrestrial languages are of similar importance like "begin", "end" or ";" in Pascal.
I assume that you want to use the text to speech capabilities of Mac OS X from Lazarus / Free Pascal.
The probably simplest way to do this is by writing:
var
s: longint;
begin
s := Shell('osascript -e ''say "Hello world! How are you?"''');
end;
The small demo application in the attachment implements this method in a flexible way.
