Formant structure encoding in newborns and adults. (a) Amplitude FFRTFS spectra extracted from the /o/ vowel section (green) and the /a/ vowel section (orange) from the stimulus, plotted separately for newborns (top) and adults (bottom). (b) Main effects graphic of F1 spectral amplitude at 452 Hz (left) and 678 Hz (right) during the /o/ vowel section and the /a/ vowel section, plotted in red and blue lines for newborns and adults, respectively. (c) Main effects of F1 SNR at 452 Hz (left) and 678 Hz (right) during the /o/ vowel section and the /a/ vowel section, depicting neural responses from newborns (red) and adults (blue).
