Laboratory Sessions

Phonetics

Goals

Automatic segmentation of the acoustic signal in consonantal and vocalic intervals
Classification of languages in rhythmic groups

Related Issues

Discussion of the cues for identifying boundaries of vocalic intervals
Mathematical modeling of the transition between vocalic and consonantal intervals in the acoustic signal
Statistical modeling of the acoustic correlates of rhythm

Results

Improvement of the Vocale computer program (ppt pdf)
Improvement of the statistic analysis of the acoustic correlates of rhythm (ppt pdf)

Historical Syntax

Goal

Description and modeling of the history of clitic-placement in European Portuguese from the 17th to the 19th century

Related Issues

Discussion of the contexts of variation between enclisis and proclisis in Modern European Portuguese
Classification and statistical analysis of the data, discussion of the grammars envolved in the change

Result

"Clitic placement in 17th and 18th European Portuguese texts: first results from the Tycho Brahe Corpus" (doc pdf ps)

The "Tycho Brahe" Parsing Scheme

Goal

Construction of a parsing scheme for Portuguese based on the parsing scheme designed for Middle English by Tony Kroch, as the basis for an Automatic parser for Portuguese

Result

Improvement of the "Tycho Brahe Syntactic Annotation System"

The "Sotaq" Computer Program

Goals

Developing OT models for stresses in EP and BP
Developing "Sotaq", a computer program for testing OT
Testing OT hypotheses against large corpora

Result

Improvements on "Sotaq": a good set of constraints to model EP and BP secondary stress assignment (html doc ps)

Rhythm in Written Texts

Goal

Elaboration and application of statistical tools for the identification of rhythm in written texts (html)

Previous: Phonology and the "Sotaq" Computer Program
