Table 6.
Difference (in Hz) between /∫/- /s/ category boundaries at opposing levels of each context tested in both experiments (modeled from GLMM results).
| NH listeners | NH vocoded | CI listeners | |
|---|---|---|---|
| EXPERIMENT 1 (AUDIO ONLY) | |||
| Gender (voice) | 702 | 0 | 636 |
| Vowel | 282 | 62 | 168 |
| Formant | 242 | 51 | 0 |
| EXPERIMENT 2 (AUDIO-VISUAL) | |||
| Voice | 675 | 183 | 490 |
| Face | 0 | 176 | 290 |
| Voice and face | 675 | 358 | 780 |
| Lips | 274 | 1016 | 993 |
| Vowel | 131 | 247 | 98 |
Calculation: the NH listener category boundary in Experiment 1 for female voices was 4553 Hz and for male voices was 3851 Hz; the difference is 702 Hz. A difference of 0 means that the effect was not significant in the statistical model and therefore, yielded no predicted effect of context.
