In 1st Edition AD&D if a druid shape shifts form into an animal can they speak their normal languages? I am assuming they can not, but wanted some clarification.
On a side note (but probably not of much help, since it's 2nd Edition related): The "Shapeshifter" character kit in the "Complete Druid's Handbook" allows a 7th+ level druid to change portions of her body (i.e. sprout wings, grow fangs, etc.), which would suggest that, in an animal form, she'd be capable of transforming her vocal chords to allow human speech.
