The academic paper titled "Variation in the Influence of the Emphatic Consonant 'dˁ' on the Adjacent Following 'a' Vowel in Two Arabic Dialects" by Musa Muhammad al-Ahmari investigates the phonetic influence of the emphatic consonant /dˁ/ on the neighboring /a/ vowel in two distinct Arabic dialects, specifically the Palestinian (Levantine) and Saudi (Peninsular) dialects. The primary focus is to understand how the presence of the emphatic consonant affects the vowel in different word positions within these dialects.
The purpose of the study is to explore the variations in the effect of the emphatic /dˁ/ across these dialects and to contribute to the understanding of emphasis in contemporary Arabic. The scope is limited to two specific dialects, providing a comparative analysis of the phonetic changes observed.
The methodology involves recording native speakers of the Palestinian and Saudi dialects and analyzing the data using the phonetic software Praat. This approach allows for precise measurement of the formant frequencies (F1 and F2) of the vowel /a/ when it follows the emphatic /dˁ/.
Key findings reveal that the Saudi dialect exhibits significantly higher F1 and F2 values compared to the Palestinian dialect, indicating a stronger influence of the emphatic consonant on the vowel. Additionally, the Palestinian dialect shows more variation in the degree of emphasis based on vowel position within words, whereas the Saudi dialect demonstrates a more consistent influence.
In conclusion, the study highlights that the influence of emphatic sounds on adjacent vowels can vary significantly between dialects, offering insights into the phonetic characteristics of emphasis in contemporary Arabic. The findings suggest that regional differences play a crucial role in the phonetic realization of emphasis, which has broader implications for the study of Arabic phonology and dialectology.
