The say command on a Mac OS X system can be used to have the system vocalize text you type. E.g., at a Terminal window (the Terminal application is found in
Applications/Utilities) you could issue the command say
"Hello world". Though you can include a period or question mark
at the end of the text, if you include an exclamation mark, since that
has a special meaning to the shell, you will get an error message.
$ say "hello world" $ say "hello world." $ say "hello world?" $ say "hello world!" -sh: !": event not found
You can have the words in a file spoken by using say -f filename
where filename is a text file containing whatever text you
wish the system to read aloud. E.g., to read the contents of
saythis.txt, I could issue the command
say -f saythis.txt.
