Simp Chinese Dictionary (Ch-Ch) with Putonghua pronunciation

[alicechen]

Hi all

Does anyone know of any software (Windows PC, Palm OS or Windows CE) offering:

(1) a Simplified Chinese (Chinese-to-Chinese) dictionary

(2) Putonghua pronunciation of individual characters and, ideally, phrases. This would preferably be done via a real human voice, not synthesized.

I am keen to learn Chinese using a PC or PDA, and any pointers will be most helpful and welcome.

Thanks in advance!

Peter
