I haven't seen it said in the course anywhere, but when I listen to the conversation, it seems often that when one word ends in a vowel and the next starts with one, that the two sounds blend into one.
An example from unit 4.10: "Noi siamo arrivati ..."
Sounds like "Noi siamarrivati ..."
Is this right? Are there any rules for how people generally speak like this?
