الصوت الساذج عند ابن جني في كتابه سر صناعة الإعراب وموقف غانم الحمد منه دراسة وتحليل

This research examined a concept from Ibn Jinni's phonetics, which is the "voiceless sound" in his book, (The Secret of Arabic Syntax Industry). It presented Ibn Jinni's idea and Ghanem Qadouri Al-Hamd's objections to this idea in his study titled "The Concept of the Voiceless Sound and Its Impact on Modern Arabic Phonetic lesson." It also clarified the modern phonetic perspective on the process of sound production. Therefore, this study focused on explaining the concept of sound production in Ibn Jinni's work, Al-Hamd's objections to it, and the modern phonetic view on the idea of sound production.This study aimed to elucidate Ibn Jinni's concept of sound production in his book (The Secret of Arabic Syntaxindustry), explore the reasons behind his perspective on defining sound and the process of sound production, and clarify Ghanem Al-Hamd's objections to Ibn Jinni's concept of the voiceless sound and discuss them. This was achieved through the examination of the idea of sound production among contemporary phonetic scholars.
In this study, the both researchers employed a descriptive and analytical approach to examine the concept of the voiceless sound in Ibn Jinni's work and to elucidate the objections raised against it and discuss them. The study was divided into two chapters. The first chapter addressed the concept of linguistic sound and its production in Ibn Jinni's book,) The Secret of Arabic Syntaxindustry (Meanwhile, the second chapter focused on Ghanem Al-Hamd's objections to the concept of the voiceless sound in Ibn Jinni's work within the context of the perspective of contemporary phonetic scholars.
It can be said that the reason for the objections and discrepancies among ancient and modern phonetic scholars regarding the concept of the voiceless sound is that the ancient phonetic scholars were not well-acquainted with the internal divisions of the vocal tract, such as the vocal cords, the larynx, and the cavities. Nevertheless, they did refer to the area of the vocal tract and its role in articulation, whispering, and sound production. They divided the vocal tract into sections and explained the function of each section in sound production. This was evident in their discussions on the sound of "Hamzah," and this represents a significant achievement considering the limited resources and rudimentary experiments available in their time.
