Is it possible for animals to make sounds other than the ones they do? For example, could a cow say "milk" if it were trained to? Why don't animals make a variety of noises/why do they sound the way they do?

Sorry, I know this is a jumble of questions, but I just walked in on my sister-in-law asking her dog to say "I love you." I know the dog isn't going to say the words but... why not?

Range of vocalizations is mechanically constrained by shape of the larynx, shape of the vocal chords, shape of oral and nasal cavities, and tongue musculature, to name just a few factors. So even leaving aside the question of training (which gets into neuroscience), it's not a given that a specific animal can reproduce a specific human sound. 

Interesting sidebar: while human upper airway structures are well-adapted for versatile vocalization, they are poorly adapted to protect against choking (in comparison to other animals).
