11/12/2023 0 Comments Praat script duration manipulation![]() ![]() Other acoustic properties that covary with VOT - such as fundamental frequency and formant transitions - are also discussed, along with considerations for testing VOT perception and its relationship to various other measures of auditory temporal or spectral processing. This paper contains a thorough description of the "progressive cutback and replacement" method of VOT manipulation, and comparison with other VOT manipulation techniques. ![]() N2 - Voice onset time (VOT) is an acoustic property of stop consonants that is commonly manipulated in studies of phonetic perception. T2 - A tutorial and flexible Praat script Last updated Jan 9 2017.T1 - Manipulation of voice onset time in speech stimuli *note that this website is no longer fully functional, as I some of my group members may have deleted some of the necessary files from their CS accounts. The code is written mostly in Python, with some C. Winter 2014 semester: In Software Systems, I worked in a group to create this website*, which isn't very pretty but has a fairly functional back-end: you can log in, create an account, and access surveys saved to your account, in addition to being able to fill out surveys and see the results of what people have filled out. I also wrote/extended some LISP code in my Computational Psychology class, to simulate learning of a task spreading through a social network of birds, better simulate evolution of enthnocentrism in a population (this problem is based on the prisoner's dilemma), and better simulate cessation of learning. (Most of the work on this project went into training/improving my evaluation function.)įall 2015 semester: I implemented various NLP algorithms in Python for my NLP class: a document classifier using bigram/unigram language models, an Earley parser, Lesk's Algorithm for word sense disambiguation (using WordNet), and a modification of SumBasic (for multi-document extractive summarization). Spring 2016 semester: For my AI class, I wrote an agent in Java which plays Hus using minimax with alpha-beta pruning. McHacks 2016 Smaller Projects & Class Projects/Assignments WearHacks Montreal 2015 *I was not a hacker at WearHacks, but one of the organizers. I use the aligner frequently and deal with any errors that arise. I trained new models for English and French based on a larger dataset, using the training function built into the aligner.I have also fixed errors in Python scripts used to prepare our data occasionally. September 2014-Summer 2015: work on the Prosodylab Aligner. and for educating new RAs on how to run the scripts and aligner) (I also am responsible for fixing any problems in the prosody lab that other RAs have with our Praat scripts for annotation, truncation, etc. The experiments run in MatLab using a file based on our experiment template, which I slightly modified. In fall and winter 2015/2016 I ran perceptual experiments with stimuli created using the script. My advisor was David Yarowsky.Īugust 2015-November 2015: script in Praat (linguistics software with its own Bash-like language) for pitch and duration manipulation. Three projects (in addition to writing several smaller pieces of code for various other tasks): learning translations of grammatical terms based on the content of Wiktionary tables, in order to improve the quality/usability of data scraped from foreign editions of Wiktionary finding and assigning probabilities to new phrasal translation templates attested in a (Uyghur-English parallel) corpus building a morphological generator for Kyrgyz which generates all possible correct inflections and feature vectors of their meaning when given a noun or a verb. May 2016-July 2016: internship at the CLSP, working on machine translation for low-resource languages (in Python). Included in this vowel lengthening paper is an evaluation of the Montreal Forced Aligner on a gold standard human annotation against both another human and against the older Prosody Lab Aligner. Some experience with: SQL, Android app dev, JavaScript ProjectsĪpril 2016-May 2016 and August 2016-Fall 2016: testing the Montreal Forced Aligner on various datasets and edge cases to find any bugs, and aligning data from an experiment on vowel lengthening in preparation to write a paper on the results. Good knowledge of: Bash, R, C (this is rusty though), HTML + CSS, UNIX command line Proficient: Java, Python, Praat scripting, F# Contact Computer Science Projects Languages. ![]()
