المد اللازم الكلمي في القرآن الكريم : دراسة صوتية فيزيائية

Abstract EN

This research involves the explanation of the phenomena of the compulsory lengthening in word of the Qur'an , for its importance in the Qur'anic performance from an aspect, and its affectivity by the phonic features of the Arabic language from another .

This phenomena was a subject of the former and the modern scientists' argument , because of their different points of views that involve the lengthening letters .

The former scientists agreed that these letters are consonants which are preceded by a short vowel of its kind , but the moderns approved that it can't be described of being consonants , because they are originally vowels of what precede it.

This argument was reflected on their explanation of the phenomena , so the researcher sought for resolving this dispute of the consonant case and whether the lengthening letters are consonants or vowels , and building the theory based on this argument to explain the issue of the research .

He also applied the spectral and oscillatory data of the program called "Praat" for the analysis of the examples and favoring between the included standpoints .

Additionally ,the research also deals with a variety of other phonetic cases of that clarify the perspectives of this phenomena , like the features of the lengthening sounds that includes simplicity, composition , its ability to extent its time span , its role in the attainment of the phonetic harmony and the pronunciation's acceleration and facilitating .

These cases also involve the effect of the reduplication on the phonetic construction of the doubled silent letter including its time span , strength , and its vocalization for the accomplishment of the rhythmic diversity of the containing word .

The researcher applied the descriptive approach considering all its procedures and regulations that cover collection , classification , analysis, and interpretation .

This approach also applied on specific phonetic record which is the Qur'an recited by sheik Mahmoud Khalil Al Hosary .

He also resorted to the experimental method to analyze the spectral and oscillatory characteristics of the examples found in the Qur'an, and the allocation of its phonetic physical value related to the study and the contained objectives .
