Hola Shirley

I've changed the voice used for those questions testing "cabríais" (conditional) because the automated voices that were used before weren't very clear and it was too fast. It should sound better now and you should be able to distinguish better the sound "ice" at the end, which is indeed the correct pronunciation for the end "-íais" :  [ee - ice]

To have a pronunciation [ace] as you said you would have to have this ending: -éis. You find this ending in the vosotros form of the future, e.g. "Vosotras no cabréis en el cine." (You won't fit in the cinema.)

I hope it helps.

Saludos
