Phonetic imitation of phonetic cues that signal phonological contrasts-e.g. voice onset time, signaling the /t/-/d/ contrast-is generally non-linear. However, previous work on how phonological categories mediate imitation has focused more on cues to segmental contrasts (i.e., vowels and consonants), neglecting suprasegmental contrasts (e.g. tones). This dissertation examines phonological effects and phonetic variations in imitation, for two cues to tonal contrasts: F0 and duration.This dissertation contains three studies. The first study examines imitation of the flat-falling tone contrast in Mandarin by native speakers. Two phonetic cues to the contrast, F0 fall range (the primary cue) and duration (a weak cue), are manipulated to create a set of flat-falling continua. The distribution of imitations is analyzed by comparing the fit of Gaussian models containing one component (i.e., linear model) and two components (i.e., categorical model). The two-component model fits the F0 imitation data better, suggesting more categorical imitation. However, the one-component model fits the duration imitation data better, suggesting a more linear pattern. These results indicate that F0 imitation is subject to phonological mediation, while duration imitation is not.The second study further explores duration imitation of tones of Taiwanese Southern Min. Previous work has mostly found that duration imitation is not mediated by phonological contrasts, but using cases where duration served as a weak cue. It is unclear if duration imitation remains linear when it is an important cue, as is thought to be the case for Taiwanese Southern Min. A first experiment finds that duration is important for distinguishing T3 (mid-register checked tone, with a final glottal stop) from T33 (mid-register unchecked tone). A second experiment examines imitation of a T3-T33 continuum created by varying the duration. The imitation data is best modeled by a one-component model, suggesting that it is not mediated by the T3-T33 contrast, despite acting as a primary cue to it.The third study compares imitation of the flat-falling contrast between native Mandarin speakers and native English speakers without tone experience. We explore if speakers lacking lexical tone phonology imitate F0 range linearly or categorically, to understand the type of category which can mediate imitation-if English speakers show categorical behavior, it cannot be due to tonal categories. Results show that both groups imitate the continuum as a mix of flat and falling categories while also tracking some within-category F0 variability, indicating that both pre-existing categories and within-category variation are sources of imitation. However, Mandarin speakers' imitation is more categorical and shows hyper-articulation, suggesting it is mediated by linguistic contrasts, while the English group's imitation seems to be mediated by psychophysical contrasts.In summary, this dissertation explores phonetic imitation of f0 and duration as cues to lexical tones. The three studies show that F0 imitation can be mediated by both phonological and psychophysical contrasts, whereas duration imitation is not mediated by phonological contrasts. These results reveal that phonological mediation in imitation is dimension-dependent, shedding light on the mechanism of phonetic imitation, ultimately enriching our knowledge of language processing and production mechanisms.

520 $a L'imitation phonetique des indices phonetiques signalant les contrastes phonologiques - par exemple, le delai d'etablissement du voisement, signalant le contraste /t/-/d/ - est generalement non-lineaire. Cependant, les travaux precedents sur la maniere dont les categories phonologiques mediatisent l'imitation se sont principalement concentres sur les indices des contrastes segmentaux (c'est-a-dire les voyelles et les consonnes), en negligeant les contrastes suprasegmentaux (par exemple, les tons). Cette these examine les effets phonologiques et les variations phonetiques dans l'imitation, en se concentrant sur deux indices de contrastes tonals: F0 et la duree.Cette these comprend trois etudes. La premiere etude examine l'imitation du contraste tonal "plat-descendant" en mandarin par des locuteurs natifs. Deux caracteristiques phonetiques signalant le contraste, la plage de chute de F0 (l'indice principal) et la duree (un indice faible), sont manipulees pour creer un ensemble de continus "plat-descendant". La distribution des imitations est analysee en comparant l'ajustement de modeles gaussiens contenant une composante (modele lineaire) et deux composantes (modele categoriel). Le modele a deux composantes s'ajuste mieux aux donnees d'imitation de F0, suggerant une imitation plus categorielle. Cependant, le modele a une composante s'ajuste mieux aux donnees d'imitation de la duree, suggerant un schema plus lineaire. Ces resultats indiquent que l'imitation de F0 fait objet d'une mediation phonologique, tandis que l'imitation de la duree n'en fait pas.La deuxieme etude explore davantage l'imitation de la duree des tons du Minnan du Sud du Taiwan. Les travaux precedents ont majoritairement conclu que l'imitation de la duree n'est pas mediatisee par les contrastes phonologiques, en se basant sur des cas ou la duree servait d'indice faible. Il n'est pas clair si l'imitation de la duree reste lineaire lorsqu'elle est un indice important, comme cela est suppose pour le Minnan du Sud du Taiwan. Une premiere experience montre que la duree est importante pour distinguer T3 (ton de registre moyen avec une occlusive finale) de T33 (ton de registre moyen sans occlusive finale). Une deuxieme experience examine l'imitation d'un continuum T3-T33 cree en faisant varier la duree. Les donnees d'imitation sont mieux modelisees par un modele a une composante, suggerant qu'elles ne sont pas mediatisees par le contraste T3-T33, malgre son role d'indice principal.La troisieme etude compare l'imitation du contraste "plat-descendant" entre des locuteurs natifs du mandarin et des locuteurs anglophones sans experience tonale. Nous explorons si les locuteurs sans phonologie tonale imitent la gamme de F0 de maniere lineaire ou categorielle, afin de comprendre le type de categorie qui peut mediatiser l'imitation. Les resultats montrent que les deux groupes imitent le continuum comme un melange de categories "plat" et "descendant", tout en suivant egalement une certaine variabilite de F0 a l'interieur des categories, indiquant que les categories preexistantes et la variation intracategorielle sont sources d'imitation. Cependant, l'imitation des locuteurs mandarins est plus categorielle et montre une hyper-articulation, suggerant qu'elle est mediatisee par des contrastes linguistiques, tandis que celle du groupe anglais semble etre mediatisee par des contrastes psychophysiques.En resume, cette these explore l'imitation phonetique de F0 et de la duree en tant qu'indices des tons lexicaux. Les trois etudes montrent que l'imitation de F0 peut etre mediatisee a la fois par des contrastes phonologiques et psychophysiques, tandis que l'imitation de la duree n'est pas mediatisee par les contrastes phonologiques. Ces resultats revelent que la mediation phonologique dans l'imitation depend des caracteristiques, eclairant ainsi le mecanisme de l'imitation phonetique et enrichissant nos connaissances sur les mecanismes de traitement et de production du langage.
