Substitution phonological patterns in the English speech of Ghanaian children

When children find the production of a speech sound difficult, they tend to substitute it with another easier one, a phenomenon described as Substitution Phonological Pattern (SPP). This study investigated SPP in Ghanaian preschoolers, who spoke their individual Ghanaian languages like Akan and Ga as their first languages (L1) but were learning to speak English as a second language, to understand and document how these children pronounced English speech sounds. Thirty preschoolers in a privately-owned basic school in Kumasi were selected and voice recorded as they mentioned twenty English lexical items from their textbooks after their teacher. Both the participants' and their teacher's productions of the stimulus words were transcribed according to the International Phonetic Alphabet. The data was analysed using both qualitative and quantitative research approaches and within the framework of Natural Phonology Theory. Findings indicated that the children exhibited Fronting, Backing, and Stopping. The participants' L1 and age among other factors were observed to be responsible for the processes identified: English sounds that were absent in the L1 of the children were difficult to produce for some of the children, while older children exhibited fewer cases of substitution. This study might serve as a documented material and a reference point for future researchers and Ministry of Education of the Republic of Ghana on Ghanaian children phonological experiences as regards the speaking of English. © 2023 The Author(s)
