Standard Chinese distinguishes a three-way place However, previous studies have suggested that distinction among sibilants: (Denti)-Alveolar /s/, retroflex sibilants in TM are gradually losing their ‘Retroflex’ (Post-Alveolar) /ʂ/, and (Alveolo)-Palatal distinctiveness from alveolars, with neutralization /ɕ/. While Taiwanese Mandarin generally preserves conditioned to some extent by register and the standard consonant inventory, previous studies sociolinguistic factors, and with this trend more have described its retroflex coronals as being partially advanced in the southern districts of Taiwan [10, 3, merged with alveolars, with higher acoustic center- 14]. A recent acoustic study comparing spectral of-gravity values for retroflex sibilants indicating a center-of-gravity (COG) measures showed that more forward place of articulation relative to although the alveolar-retroflex contrast is still comparable values for Beijing Mandarin; however maintained in TM, the retroflex sibilants have a these are to date unsupported by kinematic higher COG than their counterparts in SC, indicating measurements. a more forward and less distinctive place of Here we examine the articulation of these sounds articulation [4]. This is consistent with a subsequent using electromagnetic articulometry (EMA). Tongue combined EMA/palatographic study of TM speakers tip and parasagittal blade sensor elevation angles are showing alveolar rather than post-alveolar place compared to a reference /s/ position.
