Hello Shan Shan,
First off, welcome to the forum!
To change all of your lessons and presets' playback settings to use the Chinese Woman recordings, what you'll need is the Override button. Simply turn Override on, and then modify the Override Settings so that all your Number and Math presets use the Chinese Woman sound set.
Please refer to your Little Math manual for details on how to set up your Override Settings -- just click on the Help button in Little Math, or visit this page:

I hope this helps!
Cheers,
Kezia
