“…Tonal coarticulation is relatively well studied cross-linguistically, and universal tendencies as well as language-specific properties have been identified. In particular, languages are known to share assimilatory progressive tonal coarticulation, whereby a tone partially assimilates to the preceding tone, and the effect of this coarticulation is relatively large, but languages differ with respect to the degree of regressive tonal coarticulation -the influence of a tone on the preceding tone -and whether this coarticulation is assimilatory or dissimilatory [SC: Ho, 1976;Shih, 1988;Shen, 1990;Xu, 1994Xu, , 1997Xu, , 1999Xu, , 2001Taiwanese: Cheng, 1968;Lin, 1988;Peng, 1997;Vietnamese: Han and Kim, 1974;Brunelle, 2003Brunelle, , 2009; Thai: Abramson, 1979;Gandour et al, 1992aGandour et al, , b, 1994Potisuk et al, 1997]. Another goal of this research is to situate Tianjin in the typology of tonal coarticulation and provide a further test to both the universal and language-specific properties of this phonetic phenomenon.…”
