At an employer's request, a course was developed to improve the speech skills, and remediate fossilized speech, of six Asian engineers and scientists. All had spoken English for many years, and averaged 10 years of residence in the United States. These students were recorded reading a dialogue as well as in free speech. A needs assessment was performed by analyzing the recordings and by tests of grammar and listening comprehension. Based on the results, instruction focused on developing more comprehensible speech, using existing knowledge of vocabulary and structure. Emphasis was placed on suprasegmentals and certain problematic phonemes, with some work on grammatical errors. Techniques were used to stimulate student motivation to improve speech. Instruction consisted of teacher explanations and demonstrations, structured oral practice, communicative activities, and laboratory and home work with language tapes. At the end of the course, three students clearly demonstrated improvement. All students felt they had benefited from the course and petitioned to have it extended. Teaching students with fossilized speech requires a different approach, focusing more on form and paying greater attention to student motivation. Small classes, individualization, and improvement of student self-monitoring are advisable. (MSE)
