There are two kinds of interactions most people picture when they imagine speaking with an artificial intelligence: either the weird, stilted, and oddly-digitized Text-To-Speech scripts we all played with on our original 90s desktops, or the eerily on-point diction of HAL doling out even awful news with inflectionless apathy.
