The Intonation of Vocative Expressions in Surah Al-A ‘Raf

An Automated Pragmatic–Phonetic Study

Abstract

This study investigates the intonation of the vocative style in Surah Al-Aʿrāf through an integrated approach that combines pragmatic analysis with automated acoustic measurement. It aims to uncover the relationship between the illocutionary force of discourse and the intonational features accompanying Quranic recitation. The research is grounded in the hypothesis that intonation in Quranic recitation is not merely an aesthetic phonetic feature, but rather a functional pragmatic device that contributes to conveying the communicative intentions of the text. To achieve this aim, the study adopts a descriptive-analytical methodology supported by a quantitative acoustic approach. Key acoustic nparameters were extracted using Praat software, including fundamental frequency (F0), intensity, and duration. In addition, the study analyzes intonation contours across four selected samples representing diverse pragmatic patterns of vocatives in Surah Al-Aʿrāf. The findings demonstrate a clear correlation between the pragmatic context of discourse and the intonational features of vocal performance. Directive contexts tend to exhibit relatively stable pitch contours, whereas emotionally charged contexts such as warning and challenge (incapacitation) are marked by wider pitch ranges and higher intensity levels. In contrast, supplicatory contexts are characterized by lower intensity and longer utterance duration. The study concludes that intonation in Quranic recitation functions as a significant pragmatic indicator, effectively reflecting the illocutionary force of discourse, as acoustic features systematically vary in accordance with different communicative intentions.
