Acoustic Features and Auditory Impressions of Death Growl and Screaming Voice

In the contemporary music scene, the death growl and screaming voice are often used in the extreme metal, and have been one of the indispensable singing styles. In this study, we made an attempt to clarify the acoustic feature of the death growl and screaming voice. We chose jitter, shimmer and HNR as the acoustic features, and found that the death growl and screaming voice have much larger jitter and shimmer, lower HNR compared with the normal voice. Next, we investigated the relationship between subjective impression and acoustic feature, and found that the screaming voice has an optimum jitter.
