The Arabic consonant inventory lacks a few English consonants. This difference opens up a number of avenues for empirical research in L2 speech learning among EFL Arab learners of English. The present study, thus, aims to investigate the extent to which (1) phonological processes (i.e., voicing, devoicing, stopping, deaffrication, palatalisation, and velarisation) take place in Yemeni EFL learners’ production of six target English consonants (i.e., /p/, /v/, /θ/, /ð/, /tʃ/, and /dʒ/); and (2) word position affects the frequency of these phonological processes in the production of the investigated sounds by Yemeni EFL speakers of English. Six Yemeni postgraduate students at Utara Universiti Malaysia (UUM) (three males and three females) were recruited for this acoustic phonetic study. They learn English as a foreign language (EFL) in Yemen
