Acoustic Analysis of English Long Vowels Produced by Pashto Speakers

The present study investigates the acoustic properties of English long vowels produced by Pashto speakers by highlighting the problematic areas for Pashto speakers learning English. The data was collected from ten Pashtun learners of English through tape recorder. The data was analyzed using PRAAT software. The spectrograms produced by the software helped us in specifying the acoustic values (formant frequencies of F1 and F2) of target vowels compared with the production of the same vowels by native speakers of English. The analysis of the collected data revealed the problematic areas of English long vowels for Pashtun learners of English. The study proved that English long vowels like /I:/ and /a:/ were more problematic for Pashtun learners. A significant difference was seen in both the height and backness of the target English vowels produced by the subjects. The English vowels like /e:/ and /o:/ produced by subjects were like those produced by the native speakers. Similarly, target vowel like /u:/ was pronounced by subjects like native speakers of English. The study recommends that Pashto speakers should be given proper training for acquiring correct pronunciation of English.
