Electroglottography for voice analysis

Marc Garellek, UC San Diego

Electroglottography (EGG) provides an indirect measure of the degree of vocal fold contact, and therefore is a useful and portable tool for confirming the presence of voicing and determining the physiological fundamental frequency (f0), as well as for measuring differences in phonation types or voice quality during consonants and vowels.

The planned tutorial will provide a brief overview on how to use an EGG, what it can and cannot measure, and its primary uses in linguistic research.  We will then proceed to analyze a dataset with EGG and audio recordings for changes in f0 and voice quality across consonants and vowels, and show how EGG measures relate to acoustic measures of voicing, f0, and voice quality.
Slides from the tutorial are available here.
