Abstrakt¶
The paper addresses reflection of microintonation and spectral properties in male and female acted emotional speech. Microintonation component of
speech melody is analyzed regarding its spectral and statistical parameters. According to psychological research of emotional speech, different emotions are
accompanied by different spectral noise. We control its amount by spectral flatness according to which the high frequency noise is mixed in voiced frames
during cepstral speech synthesis. Our experiments are aimed at statistical analysis of cepstral coefficient values and ranges of spectral flatness in three emotions
(joy, sadness, anger), and a neutral state for comparison. Calculated histograms of spectral flatness distribution are visually compared and modelled by Gamma
probability distribution. Histograms of cepstral coefficient distribution are evaluated and compared using skewness and kurtosis. Achieved statistical results
show good correlation comparing male and female voices for all emotional states portrayed by several Czech and Slovak professional actors.
