Résumé : This chapter examines whether problems encoding speech may be a basis for the phonological weaknesses documented for struggling readers. Research conducted to explore this question primarily has used three measures of speech perception: categorical perception, nonword repetition, and speech-in-noise. Evidence from each of these measures is reviewed and critiqued. For categorical perception, problems with the traditional paradigm are identified, but a newer application of this measure focusing on developmental changes in speech perception looks promising. Nonword repetition, though interesting, entails many levels of processing and shows influences from vocabulary knowledge, making it difficult to isolate perceptual processes. Finally, the speech-in-noise procedure has yielded noteworthy results indicating that the locus of speech perception is central rather than peripheral. Further, the magnitude of unique variance accounted for by speech-in-noise perception points to the merit of continuing to use this task to explore bases of individual differences in reading acumen.
