Abstract

Objective:To explore the characteristic of lexical tone perception in native-Mandarin speakers with mild to moderate sensorineural hearing loss. Method:Three types of continuum(Tone1/tone2, tone1/tone4 and tone2/tone3) were constructed and each of them includes a 15 stimuli. All speech stimuli in these three continua were resynthesized by applying the Pitch-Synchronous OverLap and Add(PSOLA) method implemented in Praat to the same mandarin syllable, /a/, with a high level tone produced by a female native-mandarin speaker. Twenty-three native-mandarin sensory hearing loss people were recruited for this study and identification task was used to acquire the tonal perceptual data. SPSS 19.0 software was used to get the fitting curves of lexical tone perception. Result:①Each tone perception curves owns the characteristic of categorical perception, including an obvious boundary, a definite intersection and the abrupt performance change at intersection. The tone perception curves were S-shape in SNHL people which were same as that in normal hearing people.②No significant performance difference of each continuum was observed between SNHL and NH in this study(P=0.811 in T1/T2 continuum, P=0.528 in T1/T4 continuum, P=0.555 in T2/T3 conti...Continue Reading
