TABLE I.

Corpus of Mandarin syllables used in this experiment, grouped by tone pair, phonetic structure, and with pinyin romanization, phonetic transcriptions, English glosses, and frequency counts (appearances per million words of text).

TABLE II.

Discrimination performance rankings, and d’ values, for tone pairs in Normal Audio (AO and AV combined), Cochlear Implant Audio Only (AO-CI), Cochlear Implant Audio-Visual (AV-CI) (with CI Visual Augmentation, i.e., AV-CI minus AO-CI, listed alongside) and Visual-Only conditions (VO).

Generic image for table
TABLE III.

Coefficients of acoustic predictors of “Change” responses in same and different AX trials across the 5 experimental modalities, separated by language background (Mandarin (M) and Australian English (AE). All are significant at the 0.05 level, with italics and boldface marking significance at the 0.01 and 0.001 levels, respectively.
