Is 'not bad' good enough? Aspects of unknown voices' likability

From the DTAG likability database the 30 most and 30 least likable ones have been selected for further phonetic analysis and expert questionnaire. In contrast to dislikable speakers, likable ones exhibit almost no perceivable accent, command style or disfluencies and were rated very high on all six questionnaire scales. Dislikable speakers are only moderately rated. However, dislikable speakers display also lower pronunciation precision, different amounts of jitter, lower articulation rate and higher pitch, indicating that just the absence of negatively perceived characterizations is not enough to become a likable speaker.
