Translation:Fortunately, your assistant reminds you of everything!
I hear it in the female voice on my Mac at full speed. It's subtle, though, and I might not hear it if I didn't now know it's there. She's pausing slightly between assistante and te rappelle and I can hear the 't' on each side of that pause. The two consecutive 't' sounds make this one tough, though. She could exaggerate it more, but it would then be unnatural.
The hearts system makes things like this far more infuriating than they need be.
