چکیده:
This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree of activation of the portrayed emotions. The results also indicate that FO/pitch and other vocal aspects affected by emotion and/or emotional arousal in collected samples of speech in Persian.
خلاصه ماشینی:
Considering the above-mentioned points the present research aims to investigate the pitch range variation conveying the expression of emotion and attitude in samples of real Persian speech.
To this end, detailed acoustic information on four basic emotions (anger, sadness, joy and neutral) expressed in speech by six speakers (3 males and 3 females) are obtained.
79-163) also explored pitch range variations in production and perception of Dutch speech conveying six emotions or attitudes: joy, anger, sadness, boredom, fear and indignation against neutrality as a reference.
Then, Statistical analysis of all measures related to each sample utterance contributed us to hypothesize that significant differences would be found between the acoustic cues used by the speakers to express emotions: neutral, sadness, joy and anger.
The Spectrograph of the First Peak, Befarm?id , for Joy Expression of Sample 1 In what follows, the interface between the acoustic parameters: duration, pitch range and tilt and the portrayed emotions will be explored in details.
Counter hypothesis: the duration in the first peak (first/second half) of the same utterance to be related to the emotions sadness, joy and anger in males and females showed significant difference.
Counter hypothesis: the tilt in the first peak (first/second half) of the same utterance to be related to the emotions sadness, joy and anger in males and females showed significant difference.
Statistical results in table 5 indicate that the difference between the tilt and intended emotions: joy, anger and sadness for females in the first half rise and fall rise of utterance (4) is significant.
