This paper seeks to apply an acoustic phonetic methodology to measure and account for the impressionistic assessment of the speech of three brothers whose relatives, friends, and acquaintances say “they sound exactly alike.” The current investigation is limited to the pronunciation of the 11 phonemic monophthong vowels in American English. The psychoacoustic instruments of masking and Just Noticeable Difference (JND) are used to verify if the brothers “sound alike” acoustically. The correlates of the vowels that are investigated in this study are F0, F1, F2, F3, intensity, and duration.
