A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.

You make a very important point that I would like to emphasize: incommensurate bodies very likely will lead to misunderstanding. It's not just a matter of shared or disjunct body isomorphism. It's also a matter of embodied interaction in a real world.
Let's take the very fundamental function of pointing. Every human language is rife with words called deictics that anchor the flow of utterance to specific pieces of the immediate environment. English examples are words like "this", "that", "near", "far", "soon", "late", the positional prepositions, pronominals like "me" and "you" -- the meaning of these terms is grounded dynamically by the speakers and hearers in the time and place of utterance, the placement and salience of surrounding objects and structures, and the particular speaker and hearers and overhearers of the utterance. Human pointing -- with the fingers, hands, eyes, chin, head tilt, elbow, whatever -- has been shown to perform much the same functions as deictic speech in utterance. (See the work of Sotaro Kita if you're interested in the data). A robot with no mechanism for pointing and no sensory apparatus for detecting the pointing gestures of human agents in its environment will misunderstand a great deal and will not be able to communicate fluently.
Then there are the cultural conventions that regulate pointing words and gestures alike. For example, spatial meanings tend to be either speaker-relative or landmark-relative or absolute (that is, embedded in a spatial frame of cardinal directions) in a given culture, and whichever of these options the culture chooses is used in both physical pointing and linguistic pointing through deictics. A robot with no cultural reference won't be able to disambigurate "there" (relative to me here now) versus "there" (relative to the river/mountain/rising sun), even if physical pointing is integrated into the attempt to figure out what "there" is. And the problem may not be detected due to the illustion of double transparency.
This gets even more complicated when the world of discourse shifts from the immediate environment to other places, other times, or abstract ideas. People don't stop inhabiting the real world when they talk about abstract ideas. And what you see in conversation videos is people mapping the world of discourse metaphorically to physical locations or objects in their immediate environment. The space behind me becomes yesterday's events and the space beyond my reach in front of me becomes tomorrow's plan. Or I alway point to the left when I'm talking about George and to the right when I'm talking about Fred.
This is all very much an empirical question, as you say. I guess my point is that the data has been accumulating for several decades now that embodiment matters a great deal. Where and how it matters is just beginning to be sorted out.
Sure, I agree that we make use of all kinds of contextual cues to interpret speech, and a system lacking awareness of that context will have trouble interpreting speech.For example, if I say "Do you like that?" to Sam, when Sam can't see the thing I'm gesturing to indicate or doesn't share the cultural context that lets them interpret that gesture, Sam won't be able to interpret or engage with me successfully. Absolutely agreed. And this applies to all kinds of things, including (as you say) but hardly limited to pointing.
And, sure, the system m... (read more)
