EUROSPEECH 2003 - INTERSPEECH 2003
In this study we examine a number of characteristics of angry Hebrew speech. Whereas such studies are frequently carried out on acted speech, in this study we used recordings of participants in broadcasted, politically oriented talk shows. The recordings were audited and rated for anger content by 11 listeners. 12 utterances judged to contain angry speech were then analyzed along with 12 utterances from the same speakers that were judged to contain neutral speech. Various statistics of the F0 curve and spectral tilt were calculated and correlated with the degree of anger, giving a number of interesting results: for example, though pitch range was significantly correlated to anger in general, pitch range was significantly negative-correlated to the degree of anger. A separate test was conducted, judging only the textual content of the utterances, to examine the degree to which it influenced the listening tests. After neutralizing for the textual content, some of the acoustic measures became weaker predictors of anger, whereas mean F0 remained the strongest indicator of anger. Spectral tilt also showed a significant decrease in angry speech.
