Voice attributes affecting likability perception

Abstract

Ratings of voices ’ likability were collected in two successive studies. A single scale seems to be sufficient for assessing such ratings. Based on limited but controlled data, spectral parame-ters as well as f0 and articulation rate correlate with the ratings obtained. An automatic classification confirms the relevance of spectral features for the perception of likability. As a sim-ple method of collecting more data for further studies, the sin-gle scale was validated within the bounds of the small data set. Both the spectral parameters and items from a comprehensive questionnaire indicate the relevance of timbre for the likability perception. Index Terms: likability, voice, timbre, speaking style 1.
