ABSTRACT The Functional Load (FL) principle predicts that a high FL phonemic substitution lowers the intelligbility more than a low FL phonemic substitution. However, as yet no study has comprehensively investigated whether contextual information could attenuate any loss of intelligibility due to FL phonemic substitutions. As such, this study investigates the triangular relationship among the FL principle, word level intelligibility, and contextual information within a sentence. A Chinese speaker of English recorded sentences with more and with less contextual information that also had words with no FL substitutions, low FL substitutions, and high FL substitutions. Japanese university students transcribed the missing words from each sentence. The central hypothesis of this study is that missing words with more contextual information within their sentences will be more intelligible than missing words with less contextual information, regardless of any FL substitution. The results supported some of the hypotheses of this study, but not all.
