Sleep promotes phonological learning in children (Knowland et al., 2019)

Victoria C. P. Knowland, Fay Fletcher, Lisa-Marie Henderson, Sarah Walker, Courtenay F. Norbury & M. Gareth Gaskell
Purpose: Establishing stable and flexible phonological representations is a key component of language development and one which is thought to vary across children with neurodevelopmental disorders affecting language acquisition. Sleep is understood to support the learning and generalization of new phonological mappings in adults, but this remains to be examined in children. This study therefore explored the time course of phonological learning in childhood and how it varies by structural language and autism symptomatology.Method: Seventy-seven...

Model estimates and model comparisons (Boerma et al., 2017)

Tessel Boerma, Frank Wijnen, Paul Leseman & Elma Blom
"Purpose: Grammatical morphology is often a locus of difficulty for both children with language impairment (LI) and bilingual children. In contrast to previous research that mainly focused on verbal tense and agreement markings, the present study investigated whether plural and past participle formation can disentangle the effects of LI and bilingualism and, in addition, can point to weaknesses of LI that hold across monolingual and bilingual contexts. Method: Monolingual and bilingual children with and without...

Mandarin EL SR based on WaveNet-CTC (Qian et al., 2019)

Zhaopeng Qian, Li Wang, Shaochuan Zhang, Chan Liu & Haijun Niu
Purpose: The application of Chinese Mandarin electrolaryngeal (EL) speech for laryngectomees has been limited by its drawbacks such as single fundamental frequency, mechanical sound, and large radiation noise. To improve the intelligibility of Chinese Mandarin EL speech, a new perspective using the automatic speech recognition (ASR) system was proposed, which can convert EL speech into healthy speech, if combined with text-to-speech.Method: An ASR system was designed to recognize EL speech based on a deep learning...

Gaze to social scenes by individuals with autism (Liang & Wilkinson, 2018)

Jiali Liang & Krista Wilkinson
Purpose: A striking characteristic of the social communication deficits in individuals with autism is atypical patterns of eye contact during social interactions. We used eye-tracking technology to evaluate how the number of human figures depicted and the presence of sharing activity between the human figures in still photographs influenced visual attention by individuals with autism, typical development, or Down syndrome. We sought to examine visual attention to the contents of visual scene displays, a growing...
