“…Past studies rarely focused on the integrated processing of natural catchy sentences with various prosodic features, as we focused on in the present work. The stimuli employed in previous studies were at the word level ( Gandour et al, 1998 , 2000 ; Hsieh et al, 2001 ; Li et al, 2003 ; Feng et al, 2018a ), pseudo-sentences without semantic processing ( Hurschler et al, 2013 ), or speech that only carries one aspect of prosody, such as intonation ( Gandour et al, 2003 ; Tong et al, 2005 ), rhythm ( Geiser et al, 2008 ), and stress ( Tong et al, 2005 ; Sato et al, 2013 ). Our study provided the first insight into the neural responses responsible for the integrated processing of natural catchy sentences for children.…”

Children’s Neural Sensitivity to Prosodic Features of Natural Speech and Its Significance to Speech Development in Cochlear Implanted Children

Catchy utterances, such as proverbs, verses, and nursery rhymes (i.e., “No pain, no gain” in English), contain strong-prosodic (SP) features and are child-friendly in repeating and memorizing; yet the way those prosodic features encoded by neural activity and their influence on speech development in children are still largely unknown. Using functional near-infrared spectroscopy (fNIRS), this study investigated the cortical responses to the perception of natural speech sentences with strong/weak-prosodic (SP/WP) features and evaluated the speech communication ability in 21 pre-lingually deaf children with cochlear implantation (CI) and 25 normal hearing (NH) children. A comprehensive evaluation of speech communication ability was conducted on all the participants to explore the potential correlations between neural activities and children’s speech development. The SP information evoked right-lateralized cortical responses across a broad brain network in NH children and facilitated the early integration of linguistic information, highlighting children’s neural sensitivity to natural SP sentences. In contrast, children with CI showed significantly weaker cortical activation and characteristic deficits in speech perception with SP features, suggesting hearing loss at the early age of life, causing significantly impaired sensitivity to prosodic features of sentences. Importantly, the level of neural sensitivity to SP sentences was significantly related to the speech behaviors of all children participants. These findings demonstrate the significance of speech prosodic features in children’s speech development.
