Language has a rhythmic structure, but little is known about the mechanisms that underlie how it is planned. Traditional models of language production assume that metrical and segmental planning occur independently and in parallel (Roelofs & Meyer, 1998). We test this claim in three experiments. In Experiment 1, participants completed an…

This dissertation explores a purportedly unusual word type known as the "sesquisyllable," which has long been considered characteristic of mainland Southeast Asian languages. Sesquisyllables are traditionally defined as "one and a half" syllables, or as one "major" syllable preceded by one "minor" syllable,…

This dissertation provides an account of Zulu reduplication within the derivational framework of Distributed Morphology (DM). New Zulu data challenge the idea of reified domains like the D(erivational)-Stem and Macrostem as relevant constituents for reduplication (Downing 1997, Hyman, Inkelas, and Sibanda 2009). Instead, a crucial distinction is…

This dissertation examines floating tones and tone gesture deactivation in Sierra Juarez Zapotec (SJZ), and provides an Optimality Theoretic account of tonal spreading and placement using insights from Articulatory Phonology. While the data portion of the dissertation is drawn from SJZ, the approach has broader implications for theories of tonal…

Despite the importance of speech naturalness to treatment outcomes, little research has been done on what constitutes speech naturalness and how to best maximize naturalness in relationship to other treatment goals like intelligibility. In addition, previous literature alludes to the relationship between prosodic aspects of speech and speech…

This dissertation addresses the extent to which linguistic behavior can be described in terms of the projection of patterns from existing lexical items, through an investigation of Korean reduplication. Korean has a productive pattern of reduplication in which a consonant is inserted in a vowel-initial base, illustrated by forms such as "alok"--"t…

Speech perception requires the integration of information from multiple phonetic and phonological dimensions. Numerous studies have investigated the mapping between multiple acoustic-phonetic dimensions and single phonological dimensions (e.g., spectral and temporal properties of stop consonants in voicing contrasts). Many fewer studies have…
