The Secret of Monkey Island

was there a Talkie edition released for this and it's sequel ?

No. Of the early Lucas adventures, only Loom and Fate of Atlantis got talkie versions.

The Curse of Monkey Island (game #3) is the first in the series to have Guybrush speak with an audible voice.

However, CD versions of this game (not too sure about Secret of Monkey Island II) which features redbook audio tracks (cd quality music) rather than MIDI samples. Also some versions (not sure if it's all versions) of the CD edition feature multiple language support.

Personally I think it's worth it just because I like the song that plays on the new language selection splash screen.
