Here is a different "hello world!" by muSE on MacOSX :)
; Load the AppKit framework containing the NSSpeechSynthesizer class
[[NSBundle bundleWithPath: "/System/Library/Frameworks/AppKit.framework"]
load]
; Initialize the "hysterical" voice and say "Hello world!" with it.
(define hysterical
[[[NSSpeechSynthesizer alloc] initWithVoice: "com.apple.speech.synthesis.voice.Hysterical"]
