Hi leemr, can you kindly try playing the same lesson and check if you hear the wrong pronunciation again? Which day or lesson are you getting this problem in?
In the meantime, this may be caused by audio conflicts in your computer (especially if you find that the sound is cut off or some words aren't heard at all). Please try using the Audio Diagnostic Tool and see if it helps -- you may use this tool even for Little Math by opening it from Start > BrillKids > Support Tools.
For detailed instructions, see:
