That's the beauty of it... it encompasses so many different fields and so many different people coming from different backgrounds!
If you mean taking variations in air pressure in the audio range through a transducer to electrical form, then quantizing that in time and amplitude, then processing it digitally via DFT, then extracting phonemes from the formant shifts and so forth, and then considering where these groups of phonemes fit into a lexical database, building syntactic structures and beyond, then yes that's what it is.
We should work together!
I think my plan is, if I don't find one language I want to major in, I'll take courses in religion, language, and history. I love to learn how to pronounce new sounds, it's really neat to hear what they sound like :) . Anyway the ancient people were incredible; try looking up on the Mayan Calander.
It turns out that different fields have different sort of... well, ways of thinking right? So then, apparently in linguistics you are taking a sort of statistical approach towards poking at how the brain processes and forms speech (for example, deep structure theory). But then, in engineering... I damn figure the way to figure out how the brain works is to slice 'er open and take a scope to the damn thing. =)
