In this paper, we validate the application of an established personality assessment and modeling paradigm to speech input, and extend earlier work towards text independent speech in- put. We show that human labelers can consistently label acted speech data generated across multiple recording sessions and investigate further which of the 5 scales in the NEO-FFI scheme can be assessed from speech, and how a manipulation of one scale influences the perception of another. Finally, we present a clustering of human labels of perceived personality traits, which will be useful in future experiments on automatic classification and generation of personality traits from speech.
