Two studies on the phonology of Spanish spoken by Cubans in the United States are critically analyzed. The studies are: "Markedness and a Cuban Dialect of Spanish," by Jorge M. Guitart, and "Some Theoretical Implications from Rapid Speech Phenomena in Miami-Cuban Spanish," by Robert M. Hammond. The methodologies of Hammond and Guitart are critically examined and corrections are made of certain inaccuracies in their descriptions of Havana Spanish. The five sections of the analysis include: (1) general observations on Hammond's thesis, (2) a description of the educated Spanish of Havana, (3) a description of the people who speak the educated Spanish of Havana, (4) errors in the description of the educated Spanish, and (5) retroflex consonants of Havana Spanish. It is argued that the term "Miami Cuban Spanish" may be misleading since there are many dialects of Cuban Spanish and the people interviewed in Miami were from different parts of Cuba. (NCR)
