Browsing by Subject English students face several problems during the learning process. We see English students while acquiring this language facing several obstacles in various morphological or grammatical aspects, especially the phonological aspect, and this is due to linguistic overlap through the application of rules from the mother language in the acquired language. From this came our study to find out the relationship between the first language and the target language, that is by the phonological interference. In other words, the effect of the interference of the first language (Chaoui) on the pronunciation of English learners of as a foreign language .To determine whether or not the first language influences the pronunciation of the second language. A sample was selected from English language students from the University of Muhammad Kheidar Biskra with a Chaoui origin of approximately 19 students and had recorded their pronunciation during the performance of the tests, It is done by providing a paragraph for the students, and we record their reading to find out the location of the verbal error. After this process, the data was analyzed in the form of relative circles and tables, and the research found that the mother tongue may have an effect on the pronunciation of some letters in the target language at the level of vowels and consonants. But it is not a significant negative effect that interpolates the letters and changes the meaning of speech.
