This paper focused on glottal parameters contributing to the perception of loud voices because energy of a voice is net the only effective factor. V ´e used a formant synthesizer to synthesize loud voices. We divided FO tilt (the tilt of FO contour), Q (Speed Quotient), OQ (Open Quotient) and TL (spectral Tilt Level) into three levels to get different combinations with default values for the other synthesizer parameters. Analysis of listening tests indicated that FO tilt, Q, OQ and TL in descending order had significant influence on the perception of loud voices. FO tilt had a far more significant effect than the others. The influence of Q increased greatly with the exclusion of FO tilt as a factor. The interaction between parameters was not significant.
