	abstract = {ue to fundamental differences between the phonological systems of Bulgarian and English, 37 Bulgarians tend to disregard the qualitative-quantitative distinction between the English long and short vowel phonemes, especially between the long [i:] and the short [I] phonemes. Bulgarians articulate a different [i] sound which is easily detected perceptually and is treated as a {\quotedblbase}foreign{\textquotedblleft} accent by English native speakers. The purpose of this analysis is to determine the acoustic character of that phenomenon. The analysis is confined to monosyllabic words of the consonant-vowel [CV], and consonant-vowel-consonant [CVC] types. The investigation is based on data from the traditional spectrogram which reveals the F-pattern and the quantitative dimensions of the segments. The results of this analysis are compared to the F-pattern of the Bulgarian [i] sound, determined under similar conditions by D. Tilkov in 1968.},
