As a biologist: the basic premise of "why can can't we give .." is not remotely reasonable. Your assumptions do not match Biology. And to be fair some discussion above is anthropomorphizing some aspects of the issue.
Why?
Short answer: we cannot understand other animals verbalization (if that is what the sounds are). Plus a few other species may have some as yet undetermined language ability. Their biology, brain and ours is a mismatch.
Our brain is part of the problem:
Humans are hypersocial and have very large brain, specially adapted for verbal communication.
Not completely true in other primate species. Let's not debate what constitutes a language. Since we truly have no full understanding of any complex allospecific vocalizations.
Our brain actually creates special neural connectivity - synapses (wired) - in different ways depending on the language we use as a child. We cannot hear many foreign language sounds (phonemes) for this reason. This is the cause of an 'accent' in non-native speakers learning second languages.
Example: native Japanese speakers use a different brain structure for music than do Indo-Euopean language speakers. -- An example of the extreme plasticity of human brain development. People who learn to speak Japanese (very well) later in life have a different the music "center" than native speakers.

Other points, other species:
We cannot seem to understand another species, dolphins. A large brained species that appears to communicate in complex verbal structures. This is a brain/aural organs wiring mismatch between the species. Big time.
So we are trying out computer software and hardware to get past those limitations:

Again, we are not wired to speak dolphin ( assuming it is complex like ours is). First and foremost:. We cannot physically hear frequencies greater than ~18K cycles/sec. Some dolphin vocalizations (if that is really what they are) are higher pitched than this limit. Could be navigation, for example - like sonar.
Elephants, another large brained species, can hear subsonic sounds through their feet. We cannot hear that.
Our feet never evolved to do that. Mismatch.
Whale songs repeat and extend every year. Very complex, way beyond discussion here. Google 'Gordon Orians' who first documented the song cycles. Which can be heard across ocean basins, FWIW. Again another Biology mismatch.
So the question is interesting but a non-starter. And the assumption that language is purely human-specific could be very wrong, but we do not know. So, we may not need to teach, we may need to learn. Which is what other posters are expressing, I believe.
