On Monday, July 26, 2021, Assistant Professor Sujinat Jitwiriyanont, Ph.D., hosted an online workshop titled “A Workshop on Acoustic Analysis: Using Praat for Vowel Measurement” as a part of the LING 204: Phonology course offered by the Department of Linguistics, College of Social Sciences and Philosophy, University of the Philippines Diliman.
The workshop was divided into two sections, leading off with a lecture on the fundamentals of acoustic phonetics, particularly the acoustic properties of vowels. Following the first session, the participants were allotted to different break-out groups in order to take a more hands-on approach on vowel analysis. Leaders of the practice session included current Linguistics graduate students (Apinya Hantrakul and Apinya Singsopa) and undergraduate students majoring in Language Technology (Kantika Apinyovichien and Ratanon Jiamsundutsadee) from the Faculty of Arts, Chulalongkorn University.
Workshop entrants ranged from undergraduate students to lecturers both from UP Diliman and various other universities in the Philippines and Thailand. They were first introduced to Praat as their main acoustic speech analysis software with which the rest of the workshop would be conducted. Guided through making sense of the spectrogram, accurately segmenting vowels, retrieving formant frequency values, and visually presenting the results in the form of a vowel space diagram, the participants actively worked along and discussed theoretical and technical problems related to acoustic analyses of vowels.
