Figure 1

(a) The acoustic waveform of the stimulus/wa/. The envelope of the stimulus is highlighted in blue. The formant transition region and the vowel steady–state region are bracketed (a.u. = arbitrary units) (b) Grand-average FFR response recorded at Cz of all participants in the predictable (black) and unpredictable (red) timing conditions recorded to the/wa/stimuli presented against a continuous babbling background noise. As can be seen here, the envelope of the stimulus (a, blue) was preserved in the response (b) of both timing conditions. This is evidenced by the framed areas, which include the same number of cycles.
