English has spread in the world and it has become the international language of business and without a doubt, the most important language spoken and taught as a foreign language in Latin America. El Salvador is a country in Central America and this study presents information about the production of vowels by foreign speakers of English in this country. This is a replication of the studies conducted by Peterson and Barney (1952) and Hillenbrand, Getty, Wheeler, and Clark (1994). The participants of the study include English as a Foreign Language teachers in El Salvador. The information of Salvadorian-accented vowels includes information about six correlates including the formats F0, F1, F2, F3, duration, and intensity. The focus of the study is to assess intelligibility levels within Salvadorian-accented vowels and in comparison, with General American English which is conducted by analyzing data for the format one. Data and analysis is also conducted for the rest of the correlates because they also contribute to get an accurate representation of Salvadorian-accented vowels that can help determine how each of the vowel sounds is produced in Salvadorian Speech. The study also provides with conclusions, pedagogical implications, and potential future research in the field of Phonetics.
