Dear all,
Santiago Barreda from UC Davis (https://linguistics.ucdavis.edu/people/santiago-barreda)
will be visiting the Department of Swedish Language and Multilingualism from May 26-29. As
part of his visit, we are pleased to invite you to a half-day workshop on Tuesday, May 27,
featuring a research talk and a hands-on tutorial on formant tracking, please see schedule
below.
Date: Tuesday, May 27
Location: room D365, Södra Huset D, Frescati
13.30-14.30
Tutorial: The ‘problem’ of formant tracking, and how to use fast track.
An overview of key challenges in formant tracking will be presented, followed by an
introduction to the Fast Track tool (https://github.com/santiagobarreda/FastTrack) The
session includes basic theory, practical examples, and hands-on time for trying out the
tool and asking questions.
15.00-16.30
Talk: A Bayesian Model of Joint Vowel and Speaker Perception.
Researchers often employ normalization algorithms to transform formant representations of
vowels into more neatly invariant phonetic representations. Although these models are
meant to reflect the perceptual transformations carried out by human listeners, they
usually rely on parameters estimated 'offline' using substantial information about
the speaker. This makes them fundamentally different from speech perception in which
listeners must 'guess' the necessary speaker parameters at the same time as they
'guess' the linguistic content in the signal. I will present a Bayesian model of
vowel normalization that simultaneously estimates speaker characteristics and vowel
quality/category from individual vowels/syllables. By integrating speech perception and
the perception of speaker characteristics from limited evidence, this model offers a
better approximation of human speech perception than 'traditional' approaches to
normalization. A paper providing more detail is available here:
https://github.com/santiagobarreda/STM_paper And an R package that can be used to simulate
perceptual data is available here: https://github.com/santiagobarreda/STM
If you are interested in attending, please let me know whether you plan to join for one or
both sessions. Feel free to forward this information to anyone who might be interested.
Welcome!
Anna
