Chen-Gia, Some papers that may be of interest to you are listed below. I am running an experiment to study the perception of roughness in voice as I write this and hope to have some data in the very near future. Constraints on vocal fold physiology limit how the vocal acoustic signal can vary. These constraints must be taken into account when studying voice quality. In my opinion perception of roughness in human voices results from an interaction between SNR and frequency/intensity perturbation. Omori, K., Kojima, H., Kakani, R., Slavit, D. H., & Blaugrund, S. M. (1997). Acoustic characteristics of rough voice: Subharmonics. Journal of Voice, 11(1), 40-47. Bergan, C. C., & Titze, I. R. (2001). Perception of pitch and roughness in vocal signals with subharmonics. J Voice, 15(2), 165-175. Sun, X., & Xu, Y. (2002). Perceived pitch of synthesized voice with alternate cycles. J Voice, 16(4), 443-459.

Untersuchung der Rauhigkeit menschlicher Stimmen auf der Grundlage der nichtlinearen Dynamik und der Psychoakusik. PhD Diss., TU Berlin 2000). My preliminary experiment shows that perceptual roughness of a periodic complex tone can increase as its components at low frequencies are eliminated or reduced. This appears to contradict to existing psychoacoustic models of roughness. The stimuli and their spectra can be found at Any hints and/or references are very appreciated. Best, Chen-Gia Tsai gia(at)
