"to determine their "emotional, cognitive, and physiological" states and can tell you whether or not they're lying."
Highly improbable on the physiological level. After all, you can't take blood out of a voice. Cognitive could be argued via computers and AI.. the
emotional- where would the line be drawn? Too many things could go wrong in the integration of these as well. There is no way this is a rigidly
scientific instrument. It can't imply causation, therefore its opinion does not reflect reality 100% of the time. It ain't perfect.
