How something can be said about telling more than we can know: On choice blindness and introspection

Covert digital manipulation of vocal emotion alter speakers’ emotional states in a congruent direction
The result showed that the audio transformations were being perceived as natural examples of the intended emotions, but the great majority of the participants, nevertheless, remained unaware that their own voices were being manipulated, indicating that people are not continuously monitoring their own voice to make sure that it meets a predetermined emotional target.
