## This script extracts and plays marked vowels of the selected type in files from a selected decade.
## Vowels must be manually marked, and decade is deduced from the file name.
## Vowels can be extracted either in isolation or in the context of a target word.
## The script is designed to qualitatively assess vowel differences that are measured. With the use of the script, 
## a large quantity of vowels can be browsed relatively quickly.
## The script is written by jthoegersen@hum.ku.dk, GNU/GPL
