This study sought to identify the phonetic opinions of philosophers in Arabic
consonants and their relationship to the Arabic phonetic lesson, and to reveal the
effort they made in studying the development of consonants, and the sincerity of
the rules of phonetic development in other languages on Arabic consonants.
This study consists of many sections after an introduction. In the first section:
the research dealt with the beginnings of philosophical thinking by Arab
philosophers (Al-Kindi 256AH), while the second section: addressed the rooting
phase of phonetics by philosophers in the fourth century (Farabi339AH), and in the
third section: the research dealt with phonetic thinking in the fifth century
(Ibn Sina 428AH) and finally the fourth section dealt with phonetic thinking after
the 5th century (Razi606AH). The study concluded that the phonetic view provided
by Arab philosophers corresponds to the data of modern phonetics, and their
phonetic study is characterized by a focus on the (physical) aspect because it is one
of the most prominent topics focused on philosophy, but the phonetic linguistic
thought of vowels and consonants was present in their writings., and later this
became the base on which the modern phoneticians built their theories.
