Speech rhythm and language acquisition: an amplitude modulation phase hierarchy perspective

Abstract: Language lies at the heart of our experience as humans and disorders of language acquisition carry severe developmental costs. Rhythmic processing lies at the heart of language acquisition. Here, I review our understanding of the perceptual and neural mechanisms that support language acquisition, from a novel amplitude modulation perspective. Amplitude modulation patterns in infant‐ and child‐directed speech support the perceptual experience of rhythm, and the brain encodes these rhythm patterns in part via ne… Show more

“…In line with these observations, neuroimaging studies have repeatedly linked dyslexia with a deficit in oscillatory activity in the low-gamma band [20][21][22][23][24]. This deficit could be related to difficulties in the processing of rise time in amplitude-modulated (AM) sounds, typically associated with anomalies in slower neural oscillation ranges [24][25][26]. Young adults with dyslexia show a disrupted low-gamma 30-Hz response in left auditory cortex and abnormally strong responses at higher frequencies (around 40 Hz), suggesting that auditory sampling could be faster than in typical readers [22,27].…”

“…Strong and weak beats are grouped into a hierarchical metrical structure, which is a cognitive construct of the listener ( Lerdahl & Jackendoff, 1983 ). In spoken language, the rhythm of speech is carried by the so-called amplitude envelope, which captures information about duration, rhythm, tempo, and stress of speech ( Goswami, 2019 ; Kotz, Ravignani, & Fitch, 2018 ; Myers, Lense, & Gordon, 2019 ). When the amplitude envelope is degraded, speech can become unintelligible ( Ghitza, 2012 ).…”

“…For the PAD modelling approach, which does not make any adjustments for the cochlea, At the applied level, the possible utility of musical interventions for children with disorders of language learning such as developmental language disorder (DLD) and developmental dyslexia is supported by our modelling [60]. Such interventions are likely to be most beneficial when the underlying hierarchy of the temporal structure of music corresponds to the temporal hierarchy underpinning speech rhythm [57]. The evidence presented here regarding the perceptual commonalities between musical and speech rhythms implies that careful matching of the statistical rhythm structures across music and speech for different languages would lead to better remedial outcomes [61,62].…”
