Yes, I heard it as "in", so I assumed it was "un", not "il". The fast audio is too fast for me to distinguish the words, and the slow audio is distorted, so I often get them wrong, which is frustrating.
I am still having trouble pronouncing "Io ho ___." It sounds to me like they don't say the second "o" - like this: EE-YO EEL COLTELLO. If that's right, that's fine with me, but I keep trying to say EE-YO O EEL COLTELLO, with an extra syllable, and it doesn't seem to fit.
