Figure 6.

Scatterplots of spectral mean frequencies of the two Spanish target consonants (i.e., /s/ and /tʃ/) as a function of children's chronological age produced by the two groups of bilingual children: children with normal hearing (NHBS) and children with cochlear implants (CIBS). Each data point represents the average spectral mean frequency value for a specific target consonant produced by a single child. Lines/dashed lines indicated the best-fitted lines for the regression models of each target. For each model, the dependent variable is spectral mean frequency, and the independent variable is children's chronological age (for NHBS) or their duration of cochlear implant use (for CIBS). Shaded bands indicate 95% confidence interval.
