dc.description.abstract | Purpose: The purpose of this study is to characterize the local (utterance-level)
temporal regularities of child-directed speech (CDS) that might facilitate phonological
development in Spanish, classically termed a syllable-timed language.
Method: Eighteen female adults addressed their 4-year-old children versus
other adults spontaneously and also read aloud (CDS vs. adult-directed speech
[ADS]). We compared CDS and ADS speech productions using a spectrotemporal
model (Leong & Goswami, 2015), obtaining three temporal metrics: (a) distribution
of modulation energy, (b) temporal regularity of stressed syllables, and
(c) syllable rate.
Results: CDS was characterized by (a) significantly greater modulation energy
in the lower frequencies (0.5–4 Hz), (b) more regular rhythmic occurrence of
stressed syllables, and (c) a slower syllable rate than ADS, across both spontaneous
and read conditions.
Discussion: CDS is characterized by a robust local temporal organization (i.e.,
within utterances) with amplitude modulation bands aligning with delta and
theta electrophysiological frequency bands, respectively, showing greater phase
synchronization than in ADS, facilitating parsing of stress units and syllables.
These temporal regularities, together with the slower rate of production of CDS,
might support the automatic extraction of phonological units in speech and
hence support the phonological development of children.
