Voice attributes affecting likability perception

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 parameters 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 simple method of collecting more data for further studies, the single 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.
