The current study explores whether Mandarin initial and medial voiceless unaspirated and voiceless aspirated stops differ in their tongue positions and post-vocalic voicing during closure. Ultrasound tongue imaging and acoustic data from five Mandarin speakers revealed (1) no consistent pattern for tongue positions among speakers, and (2) no difference in degree of voicing during closure between the two stop series. These findings suggest that tongue position is not a reliable articulatory correlate for Mandarin laryngeal contrasts. This further suggests that aspiration is not correlated with tongue position differences, unlike the reported correlation between voicing and tongue root advancement.
