Abstract
When listening to the human voice, listeners are able to perceive speaker-related information, for example the speaker’s gender. Previous research has revealed that the perception of voice gender is determined by two anatomically related vocal characteristics that vary with speaker size and hormone levels: the average fundamental frequency (F0), related to the glottal pulse rate, and perceived as the vocal pitch, and the formant frequencies, related to vocal tract length (VTL), described as the voice timbre. It has been shown that speaker identification and discrimination are influenced by linguistic processing, and especially the familiarity with the spoken language facilitates voice perception. However, if this effect arises at the phoneme or word level is unclear, as well as how this influences the perception and use of certain vocal parameters, such as F0 and VTL, for speaker discrimination or identification across listening conditions. Here, we studied the effects of lexical and phonological processing on the weighting of F0 and VTL on perceived voice gender categorization in normal-hearing adult listeners by manipulating the lexical status and recording direction, and F0 and VTL properties of female reference voices. Listeners gave significantly more weight on F0 and VTL when listening to words and nonwords compared to time-reversed nonwords. This indicates that phonological processing enhances the perceptual weighting of F0 and VTL for perceived voice gender categorisa
