Previous research on pronunciation errors observed that the most frequently mispronounced English phonemes are word-initial consonants. The findings of the current study invalidate those observations by presenting the data analysis of 40 Turkish EFL learners' speech samples, which illustrates that segmental speech errors are position-independent for the target phonemes of the research (/?/, /ð/, /w/, /d/, /d[subscript 3/). The target phonemes were selected from the consonants which are caused by orthographic interference. The data were obtained through 40 sentences which contained 3 sets of each phoneme in initial, medial and final positions. The participants were asked to read the sentences aloud while being audio-recorded in a quiet environment. Analysis of the speech was performed by two native English-speaking raters. Although this was a small-scale study, its findings will pave the way for next studies. Further research is required to confirm the generalizability of the findings.
