The limits
What SPECTRIA does not measure
These are not gaps waiting to be filled in a later version. They are claims the instrument cannot support, so it does not make them.
Honesty or deception
No claim is made about truthfulness. Delivery is not a polygraph.
Personality or traits
Nothing here describes who someone is, only how one recording landed.
Intelligence or ability
A delivery measurement is not a competence measurement.
Emotion as ground truth
Facial movement is reported as movement, a smile that reached the eyes is described as exactly that, not as happiness.
