Sylvia Moosmüller back cavity affiliation of F3. Figure 4.9 also displays the stepwise change in vowel quality in dependence on the speaking task or degree of formality. The [–constricted] unrounded pre-palatal vowel /ç/ is not affected by this problem, since the originally higher constriction degree prevents a switch in cavity affiliation. It can be seen from Figure 4.10 that F2, F3, and F4 are approximately evenly spaced. Figure 4.10: Average spectrum of the vowel /ç/ taken from the logatome “pibbe”, speaker sp012. The primary difference between /i/ and /ç/ is tongue-palate distance, i.e. constriction degree. This parameter affects all formants; as constriction is widened, F1 increases 76 , and F2 and F3 decrease monotonously. Therefore, F1 has to be higher for /ç/ than for /i/, F2 has to be lower or equal 77 , and F3 has to be lower within each speaking task or prosodic position. However, Pouplier et al. (2004) pointed out that tongue-palate distances were neutralized between the pair /i/ – /ç/ for all three subjects. Tables 4.12 – 4.14 give the mean F1, F2, and F3 values for the pair /i/ – /ç/. 76 However, the degree of lip aperture is the most obvious correlate of F1 (Hoole 1997). 77 Depending on the cavity affiliation of F2. 88
