"عِنْد روزا سَمَك."
Translation:Rosa has fish.
I hear it too, it's Ruuz-an. The final ا sometimes has a little mark on top that looks like a doubled form of the stroke for short 'a', and is pronounced 'an'. But, it requires certain grammatical contexts (technically it's accusative indefinite). It wouldn't be correct here. But, I think it's simply the TTS over-predicting when it should be pronounced.
