Spoken language makes no sense. Maybe you just mean expressive, but the last thing I want is a programming language anything like the spoken word, because at least English is a colossal mess of inconsistent jibberish.

I've always been interested if someone ever tried to make a sensible spoken word - use all the enunciable syllables of the human voice (go read wikipedia on all the sounds you can make that are defined by one of the 26 English letters) with combinatorial and sensible word structure and straightforward sentence structure.

And the, ironically, best way to define something like that would be like how you define a programming language.
