Sixth International Conference on Spoken Language Processing
This paper focused on glottal parameters contributing to the perception of loud voices because energy of a voice is not the only effective factor. We used a formant synthesizer to synthesize loud voices. We divided F0 tilt (the tilt of F0 contour), SQ (Speed Quotient), OQ (Open Quotient) and TL (spectral Tilt Level) into three levels to get different conibinations with default values for the other synthesizer parameters. Analysis of listening tests indicates that F0 tilt, SQ, OQ and TL in descending order had significant influence on the perception of loud voices. F0 tilt had far more significant effect than the others. The influence of SQ increased a lot with exclusion of F0 tilt as a factor. The interaction between parameters was not significant.
