Literature Review from the year 2006 in the subject English Language and Literature Studies - Linguistics, grade: A, University of Potsdam, course: Developmental Language Disorder, language: English, abstract: Speech production, the prime language activity of human beings, involves a process of cognitive endowment. It includes some internal mechanism of language production that engages several chronological stages like auditory analysis system, phonological input lexicon, phonological output lexicon, and output buffer. Here, impairments in former two stages exhibit comprehension problems of speech production of human beings, whereas impairments in later two stages denote production deficiency in this regard (Basso, 2003: 127). In the article ‘Generalised improvement in speech production for subject with reproduction conduction aphasia’ Sue Franklin, Frauke Buerk, and David Howard depicted a case study of a patient MB who faced a problem with speech production especially phonological encoding process at the post lexical level that includes phonological output lexicon and output buffer. Thus, MB made frequent phonological production errors in all modalities but reduced significantly after some therapy sessions conducted by the authors of the article.
