This paper addresses several questions regarding the acoustic properties of Isthmus Zapotec vowels. Based on earlier recordings of a female, mother-tongue speaker of the language, average formant frequencies for each of the five phonemic vowels are determined for this speaker. I then look at differences in formant frequencies between stressed and unstressed modal vowels. Finally, I compare modal, laryngealized and checked productions of the vowels, to see if there are systematic differences between these three phonation types.
