    Syntax-Prosody in Optimality Theory (SPOT)

    Syntax (from Greek σύνταξις, an abstract derivative of συντάσσω ‘put in order together, organize, arrange’), is the set of linguistic rules, principles, and processes that govern the structure of sentences, while prosody (from Greek προσῳδίᾱ ‘song accompanying words, tone or accent of a syllable’; Latin accentus) deals with syllables, rhythmic feet, and larger units of speech that contribute to intonation, tone, stress, and rhythm. The syntax-prosody interface is the study of how syntactic (grammatical) structures are mapped onto prosodic form in different languages. The Research Cluster will be composed of five faculty members in different subfields of linguistics, two in syntax (James McCloskey and Maziar Toosarvandani) and three in phonology/prosody (Ryan Bennett, Junko Ito, and Armin Mester). Linguistics graduate students involved will be Nick Kalivoda (ABD with a research focus in syntax-prosody) and Jenny Bellik (ABD with a focus in phonology and computational linguistics). We anticipate a few other graduate students to be joining in the future.

    The fundamental problem in syntax-prosody research is to precisely predict, for any kind of syntactic structure in a given language, what kind of prosodic parse it will be assigned by the language’s grammar. Languages are known to show wide variation in this respect, and the Linguistics Department at UC Santa Cruz has a long history of work on these issues dating back to the 1990’s. In order to approach the problem in a rigorous and precise way, it is necessary to consider the full set of prosodic structure candidates for any syntactic input, a task for which no formal tool has so far been developed. At the same time, automation is essential since the number of prosodic structure candidates increases exponentially, as length and syntactic complexity increase: Under widely shared representational assumptions, 3 words receive 48 different parses, 4 words 352, 5 words 2880, etc.

    The project developed the pilot program SPOT (Syntax-Prosody in Optimality Theory), a JavaScript application that provides both exhaustive generation of the prosodic candidates, and automatic evaluation of the violation profiles of each candidate. Even though still in a preliminary form, the program has been successfully tested on well-known prosodic parsing data in Japanese and Basque. The pilot investigation has revealed that automating the generation and evaluation of candidates makes it possible to see clearly many hitherto unknown factors coming into play in the overall analysis, with interesting predictions that need to be tested in the future.

    The computational program SPOT will be made publicly and freely accessible. Beyond its immediate goals, it has clear application possibilities in natural language processing, speech technology (recognition and production, translation), as well as in second language research and teaching (e.g., to explicate the differences in syntactic and prosodic structure between the first and the second language).
