This study is conducted to find out whether mother tongue affects the English Pronunciation. The problems of this research are formatted in the form of questions, as follows: “What problems do the students have in pronouncing English words?” and “What are the causes of their mispronunciation?”. To solve the problems, the researcher uses some theories such as: Roach (2000), Jones (1979), Gimson (1962), and Skandera & Burleigh (2005). The main theory in this research is about English pronunciation which is aimed to English vowels, diphthongs, and consonants. This research is a qualitative study. The subjects are the second semester students at Teacher Training and Education Faculty Pematangsiantar. The data are analyzed by first transcribing the students_ voice into phonetic transcription, and then comparing them to the Standard English Pronunciation, after that identifying the students_ problems. The researcher finds out that the interference of students_ mother tongue, namely: Batak Toba language, makes the students difficult to pronounce some English phonemes, such as (1) vowels /_/, and /_: /; (2) diphthongs /e_/, /__/, /e_/, /__/, and /__/; (3) consonants /_/, /_/, /_/, /t_/, /_/, /f/, /v/, and /z/; and (4) suffix –s /z/ or /s/, and suffix–ed /d/ or /t/ or /id/. In conclusion, this study shows the cause of the interference of mother tongue in the students_ pronunciation is the absence of such phonemes in Aksara Batak (Batak_s Script). The researcher suggests English teachers to introduce English phonemes (consonants, vowels, and diphthongs) and stress to class of beginner, and to be a good model in teaching pronunciation.
