This workshop was conducted in the Department of English, Jahanagirnagar University on June 26, 2014.
The workshop was intended to provide a basic introduction to the acoustic analysis of speech sounds, more specifically measuring vowels from speech signals. Using the state-of-the-art software and techniques, the workshop tried to distinguish the features of speech sounds which go unnoticed to the human ears most of the time. Besides, a general overview of what acoustic phonetics is preoccupied with, it attempted to explain out how the measures of vowels qualities can be figured out from their speech signals.
Praat, a small and free, but hugely effective software, was used as the main tool for the workshop. The software can be downloaded from any of the following links:
By the end of the workshop, attendees were expected to be able to:
- describe the basic qualities of vowels: first formant (F1) and the second formant (F2),
- quantitatively distinguish between vowels in any languages, and
- create their own vowel spaces by measuring and plotting F1 and F2 values .
