The underlying stressed vowel system in Southern Salentino i ɔ Ɛ u 4. Research questions What is the articulatory nature of the F1 differences that are observed in the stressed mid vowels before high vs. non-high vowels? What is the articulatory process producing the F1 differences? Is there just a single process or are there more processes? How can we interpret these facts in phonological terms? a 9. Results 11. Conclusion 9. 1 The FRONT mid vowel before –i and –u TRICASE MIGGIANO 5. Hypotheses Fig. 1: F1 and F2 formant chart of the five Southern Salento vowels produced by 36 male speakers, and Kernel curve analysis (the most appropriate measure for cases where little is known about the process under study). The mid stressed vowels /e/, /o/ are differentiated according to the following vowel (cf. Grimaldi, 2009). 2.

Recording of the tongue movements 2 male speakers who, after a preliminary acoustic analysis, have MIGGIANO shown to possess the exemplified harmony processes and their microvariation. The stimuli were embedded in the frame sentence: I say ____ now 10 repetitions for each vowel type: 5 in open syllable (e.g., ['fi:.li] „threads‟) e 5 in closed syllable (e.g., ['frid.di] „cold-M. PL.‟). e1 e2 e3 o1 o3 o 600 2 a a 800 800 1000 3000 2500 2000 1500 1000 F2 500 1000 3000 2500 2000 1500 1000 F2 Tokens containing the mid vowels were e1 = e/__ i e2 = e/__ u e3 = e/__ e, a o1 = o/__ u o2 = o/__ i o3 = o/__ a, e u differentiated according to the final vowels (cf. 1 and 2). The F1 of stressed mid vowels lowers when the following syllable contains a high vowel. The “lowered” F1 of the stressed mid vowels does not reach the F1 values of unstressed high vowels: mid vowels become mid-high vowels. Asymmetry between the front mid vowel /ɛ/ and its back counterpart /ɔ/: F1 of /ɛ/ lowers before both unstressed high vowels (cf. 1b-c vs. 1a). ['llɛva] ['llevi] ['llevu] ‘(s/he) removes’ (496 Hz in T, 538 Hz in M) ‘(you) remove’ (407 Hz in T, 405 Hz in M) ‘(I) remove’ (472 Hz in T, 490 Hz in M) F1 of /ɔ/ lowers only before unstressed posterior high vowel The randomised stimuli were presented to the informants on a computer screen. 7. [+ATR] vs. [-ATR] vowels in the Tricase dialect The tongue root advances in [e]: [e] [+ATR] [ɛ] [-ATR] ['bbɔna] ['bbɔni] ['bbonu] ‘good-F.SG.’ ‘good-M.PL.’ ‘good-M.SG.’ (512 Hz in T, 539 Hz in M) (500 Hz in T, 547 Hz in M) (465 Hz in T, 446 Hz in M) F1 of /ɛ/ lowers more before the unstressed front high vowel than before the back high vowel (cf. 1b vs. 1c above) (2) The mid vowels become [+high] when followed by the unstressed high back vowel –[ʊ] i ɛ a ɔ u High + – – – + Low – – + – – Back – – + + (1) * [ * N X1 + Rounded – – – + + ATR + – – – + [-consonantal] * N * [ * N * N X1 X2 X2 [-consonantal] [-consonantal] Tongue Body Tongue Root Tongue Root Tongue Body Tongue Body [-consonantal] Tongue tip Tongue tip Tongue root Tongue root ['mɛ:te] ‘(s/he) reaps’ ['me:ti] ‘(you) reap’ 8. Analysis The inferential statistic analysis of the tongue contours was computed with “Smoothing Spline ANOVA” (SS-ANOVA) SS-ANOVA already used by Davidson (2006) and Lilienthal (2009). Final unstressed back high vowel are [-ATR]: * N | X [-cons, +high, +back]→ [-ATR]/ ____ [-low] [+ATR] [-high] [+high] However, the constraint *[+Back, +ATR] blocks the application of this rule to back vowels.

Phonological interpretation Assumptions: Vowels feature assignments: Fig. 4-5: Vowels produced by one 54-year-old male speaker of the Miggiano dialect. Ellipses on data, confidence level = 68,8% (on the left), and ellipses on centroids, confidence level = 95% (on the right). Our research represents the first attempt to study an Italian harmony process articulatorily and to use the data that are thus obtained to validate theoretical hypotheses (see for the Hungarian harmony Benus, Gafos, 2006). References 200 200 The US system could represent a fruitful resource in order to integrate phonetic and phonological levels. In this way, phonological models can validate and refine their predictive power. Ladefoged & Maddieson (1996): Height contrasts in Romance mid vowels are due to different positions of the tongue body with no involvement of the tongue root. Calabrese (1988, 2008),Walker (2005), a.o: These contrasts are due to the advancement/non-advancement of the tongue root, i.e. to different specifications of the feature [Advanced Tongue Root] (where [+ATR] implies an advancement of the tongue root with respect to its neutral position ([-ATR]). Calabrese (2008), following Lindau (1975): The feature [+ATR] is responsible for the tongue body convexity characterising the mid-high vowels in Romance languages. Specifically, the advancement of the TR causes raising/fronting of the TB. Additional hypothesis: The anterior dislocation of the tongue body due to the feature [+ATR] may be problematic in the case of the back vowels. There is a markedness constraint *[ +Back, +ATR]. This study provides evidence in favor of the use of US in analyzing the articulatory grounding of phonological phenomena. In particular: [+Back] a
