How would you?
I would add the words to the sound library. Either connected to their particular sounds or redefining the sound I want them to refer to.
Even if I did nothing
"'allo' sound play."
would make the default sound.

Suppose you did. How would you want to do it?
bark := 'bow wow' .
bark sound play.
bark := 'woof woof'
bark sound play.
or
bark := 'bow wow' sound .
bark := 'woof woof' sound .
bark play .
Though in the latter case I might use barkSound instead of bark as the variable.

Hmmm. In packaging the selector has been put in an extention so that it is packaged with Sound Library.
In protocol it belongs as an instance method for String class and subclasses.

You mean instead of "SmalltalkImage current platformName" ?
No, because 1005 asPlatformName has no meaning for me. It certainly would make code reading more mysterious.
When I went to read it again I would not remember why 1005 was to be associated with anything let alone PlatformName. It also seems a very straw man like example. In that case its not the programmer who should be remembering the specific index.
The principles involved here is to form the language to
1) Write intention revealing code.
2) Create as little dissonance with the language the programmer already has in his head.*
Smalltalk gives you the chance to have programming language that sounds like natural talk. That's important to use.
Yours in curiosity and service, --Jerome Peace
