VOT-CP: A Python program for automatic data codification and calculation of voice onset time


Presenter: Ernesto Gutiérrez Topete

Voice onset time (VOT) is an acoustic property of speech that is able to reveal a lot of information about a speaker’s linguistic experience(s). Analyzing VOT helps us in (a) developing linguistic theories of language representation and (b) assessing a language learner’s approximation to phonetic norms in the target language.

In this online presentation, Ernesto Gutiérrez Topete will present a computational tool (a Python program) that can be used to analyze a speaker’s VOT productions for the purposes of linguistic research or instructional student support. This presentation will cover installation and usage instructions and will provide a live demonstration of how to use the tool. There will be time for Q&A at the end of the presentation.

Automatic Text Summarization: Building Authentic Language Learning Materials with Python and NLP


Presenter: Richard Medina

Summarization refers to a Natural Language Processing (NLP) technique for automatically generating shorter length texts from longer documents. Once compiled, these summaries can be used as material in varying language learning pedagogies and in varying learning tasks. In this demonstration and discussion we will introduce the major components of automatic text summarization and its utility for building language material from authentic sources (E.g., newspaper articles, literature). In addition to providing this background, we will also demonstrate application of this technique using Python and related NLP libraries. This talk is geared towards a non-technical but extremely curious audience.
