Good but Voice Recognition Needs Work

Im learning quite a bit of Spanish. This program seems like it could be very effective. Im on Basics 2 but the problem is that it requires you to speak into the phone for some translations. About 90% of the time, Im right, but the program doesnt recognize my voice so I loose hearts. This glitch costs time and/or money. I suggest they fix it so you dont lose hearts on voice recognition exercises unless they greatly improve the program.
