Do you want to store more than one sound on one eprom and then add a switch 
to change between them?  If so, it sounds messy indeed...

But, AFAIK you can use bigger proms but just ignore the unwanted memory...
but beware of which pin is which as mentioned in Michael's pdf.

I'm still unsure about what you want to achieve and I think it might be a 
language issue. Try telling us your plans in plain english and at least I 
will do my best to assist...
