Spoken language, and arguably written language, consists of more than the sounds that indicate the words which are being produced; language is also produced with prosody, which describes the music of language, including the way in which certain words are made prominent, or the way that words are grouped. My work explores not only what prosody is, but also how it is produced and perceived.
In my lab, we explored a variety of questions related to the production and perception of speech prosody. For example, we explore the factors which determine which words are prominent, those which determine why boundaries appear where they do between words, and what a good annotation system of prosody might be. Moreover, we explore how prosodic features affect the real-time processing of language; that is, what information do patterns of stressed syllables, or locations of boundaries, convey to a listener. In addition, we explore questions about how prosodic information influences silent reading processes.
A further goal of our research is to understand how speech production and comprehension rely on more general cognitive processes, like attention, as well as how the processes that underlie speech production and comprehension are related to those that underlie music production and comprehension.
We use a variety of methods to explore these areas. We conduct behavioral experiments where we measure reaction times, ratings, or other measures of interpretation. We also use event-related potentials to measure real-time scalp electrical activity in order to more accurately measure the timing and interaction of cognitive processes.
