“…Wan (1996), Jaeger (1998), andWan (1999) presented evidence regarding the representation and processing of tone in Mandarin Chinese by examining a corpus of speech errors collected in a naturalistic setting; some of the errors were subjected to spectrographic analysis to demonstrate an accurate perception of what had been spoken. Findings in Wan and Jaeger (1998) are summarized as follows: (1) When a lexical item or word is substituted for another, the error item or word always retains its underlying tone. (2) After lexical items have been inserted into syntactic frames and their phonological representations activated, phonological processing occurs, and during this processing, segments and tones are unlinked so that they will be involved in errors independently from each other.…”
