This study acoustically examines the acquisition of emphatic consonants in Saudi-Hijazi Arabic-speaking children aged 3–6 years. Thirty-eight children performed a real-word repetition task, after which consonantal and vocalic cues to the plain–emphatic contrast were measured. Results show that children produce both types of acoustic cues, with an age-related increase in the acoustic contrast and an overall alignment with adult patterns. Larger acoustic contrasts were found in vowels preceding rather than following consonants in word-medial positions, with no evidence for a difference between word-initial and word-final positions. The plain–emphatic contrast was greater for stops than fricatives and larger for female than male children. These findings are discussed in relation to the development of coarticulated consonants.","PeriodicalId":48132,"journal":{"name":"Journal of Child Language","volume":"302 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144928545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, we conduct a corpus analysis and demonstrate that for early acquisition, both grammatical orders are neither sufficiently nor consistently supported in the linguistic input. The sensitivity patterns and input profile outlined in our study constitute the first step of testing, in a natural language setting, a bias for typologically common ordering discussed in the artificial language learning literature.
