Voice quality cues are used in tone perception. For Mandarin tones, previous studies have found that creak can facilitate or improve the identification of the low-dipping tone 3 [1,2]. Low f0 in particular was found one of the most useful cues of creak, and resynthesized period doubling was found to hinder all tone perception [2]. However, it is less clear how naturally-occurring subtypes of creak affect tone perception. Here we focus on the effects of period doubling and vocal fry, compared to modal voice, on the perceived naturalness and representativeness of Mandarin tones. A visual sort-and-rate task was implemented using naturalistic tones with varying voice qualities. Native Mandarin speakers rated tone 3 as more natural when having vocal fry or period doubling with frequency and amplitude modulation but other tones as more natural when having modal voice. The rising tone 2 and falling tone 4 were also rated lower when having period doubling with amplitude modulation. Interestingly, the high-level tone 1 and tone 3 with amplitude-modulated period doubling had similar ratings with modal voice. These results suggest that period doubling has versatile functions in different tone contours depending on the modulation type, and creaky voice is integrated in tone 3.
