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?
