Stacey, the audio for the flashcards is unfortunately not available in Pāli. The English feature was only there because the software we used automatically detected English words and used an electronic voice to read them.
We have since turned off the English feature as well.
Perhaps later we'll find a solution to this but in the mean time working with the pronunciation guide in the "Introduction to Pāli" PDF as well as the audio files in that document will prove helpful.
