In this example Je vois un soleil jaune et une fleur jaune. the pronounciation of the word jaune is very different for the first and second occurence. The first one is pronounced with an e almost like jauné, while the second one has a silent e like jaun.
Is the word pronounced differently depending on the gender, is the speech broken (it sounds very robotic), or is it pronounced differently depending on what word it comes before in the sentence (here ... jaune et ...)?
