Classic typologies within prosody tend to treat 'tone' languages as being diametrically opposed to 'stress' languages. However, Hyman (2006) highlights several languages that can have both, including Seneca, Fasu, and Copala Trique. As language documentation advances and our acoustic methodologies in the field are further refined, we have seen…

This dissertation presents three studies that examined issues related to the production and the perception of pitch in a tone language. The first study examined linguistic contexts that may modulate consonant-induced pitch perturbations (CF0) in a tone language. Previous studies have produced mixed findings regarding the role of linguistic…

This dissertation investigates the lexical f[subscript 0] control in Mandarin within the framework of Articulatory Phonology (AP) in two experiments: an imitation study (Experiment 1) and an Electromagnetic Articulography production study (Experiment 2). Empirical results are accounted for by making reference to a gestural model of f[subscript o]…

Tonal languages differ in how they use phonetic correlates, e.g. average pitch height and pitch direction, for tonal contrasts. Thus, native speakers of a tonal language may need to adjust their attention to familiar or unfamiliar phonetic cues when perceiving non-native tones. On the other hand, speakers of a non-tonal language may need to…

This dissertation investigates how the Taiwanese Tone Sandhi Groups are perceived, and the acoustic/phonetics correlates of listeners' judgments. A series of perception experiments have been conducted to scrutinize the following topics--Taiwanese tone neutralization, Tone Sandhi Group (TSG) as a prosodic domain, perceived boundary strength in…

The current study lays the groundwork for a model of Mandarin tones based on both native speakers' and non-native speakers' perception and production. It demonstrates that there is variability in non-native speakers' tone productions and that there are differences in the perceptual boundaries in native speakers and non-native speakers. There…

The research reported in these papers covers a variety of communication problems. The first paper covers research on sound navigation by the blind and involves echo perception research and relevant aspects of underwater sound localization. The second paper describes a research program in acoustic phonetics and concerns such related issues as…
