Let's suppose you are having a casual conversation with a friend and talking quickly and want to say, "Попал в бесперспективняк." Will you be able to pronounce this flawlessly and without changing the fast tempo of your speech?
I am asking because my teacher criticized me for slowing down the tempo when I pronounced that phrase. Calling my tongue clumsy, he then made me repeat this phrase many times. He made me "stress the consonants," as he puts it, and then to speed up the tempo. In the end, he got more or less pleased, but said that I still have to work in order to pronounce such phrases like a true Russian girl.
I am curious whether native speakers really have no difficulties pronouncing this phrase quickly and naturally.
