Well just first off all, Wii Speak it is only compatible with Animal Crossing (so far), so in order to have it runing through the USB Loader, you need that game, and secondly, it can't be used on cIOS_r10, cause it is based on IOS36, wich doesn't have any USB support at all, so you will need to install cIOS_r12/r13ab cause they are based on an IOS with USB support (IOS38)...!!
