If you don't mind relying on an external program you can install
espeak ( http://espeak.sourceforge.net/) and then simply do:
(define (speak text) (system* (find-executable-path "espeak") text))
(speak "Hello world")

Well, yes, if you solve the problem and plug the solution into
the teachpack as advertised, you get to hear Stephanie Weirich

Thanks. The sound.ss install worked fine from Windows 7, and plays
.wav files, as advertised.
What I was going from to expect speak-word and speak-list was this
quote from HtDP:
-----------
Once the controller returns the correct list for amounts whose dollar
and cent amounts are between 0 and 20, test the controller with a
computer that can speak. Set the teachpack to sound.ss, which makes
two operations available: speak-word and speak-list. The first accepts
a symbol or a number, the second a list of symbols and numbers. Both
pronounce the symbols they consume. Evaluate the following expressions
(speak-word 1), (speak-list (cons 1 (cons 'dollar empty))), and
(speak-list (cons 'beautiful (cons 'lady empty))) to understand how
the operations operate.
----------
What am I misunderstanding?
Thanks,
John

That's all our sound teachpack ever did. The old one is located at

As you can see, it hasn't been maintained in a while. Sorry, let us
know if it works [I don't have time right now to try.]

Hello. What happened to the sound.ss teachpack, which apparently used
to include speak-word and speak-list methods. Those sound great fun
for teaching ... but I can't find any evidence on the Web that it ever
existed, except for Google Books hits on HtDP :). (Note that there is
a deinprogramm/sound.ss file in the current distro, but that just
plays sound files, which is less cool.)
Thanks,
John
