The challenges of assessing and managing Swahili speaking children with speech difficulties are further exacerbated by the limited research available on the typical acquisition of Swahili phonology. This exploratory study aimed to describe the phonological development of 24 typically-developing first language Swahili speaking children between the ages of 3;0 and 5;11 years in Dar es Salaam, Tanzania. A cross-sectional design was used with six groups of four children in six month age bands. Single word speech samples were obtained from each child using a set of culturally appropriate pictures designed to elicit all consonants and vowels of Swahili. Each child’s speech was audio-recorded and phonetically transcribed using IPA conventions. Children’s phonological development is described in terms of a) phonetic inventory b) syllable structure inventory, c) phonological processes, and d) PCCTown and PVC. Results suggest a gradual progression in the acquisition of speech sounds and syllables between the ages of 3;0 and 5;11 years. Vowel acquisition was completed and most of the consonants acquired by age 3;0. Fricatives /z, s, h/ are later acquired and the soundsCape /θ/ and /r/ are acquired the last by age, 5;11. The shorter and simple syllable structures developed earlier than the longer and complex structures with clusters. The older children wereof able to produce speech sounds more accurately and had fewer phonological processes in their speech compared to the younger children. The study contributes a preliminary set of normative data on speech development in Swahili speaking pre-school children. Findings are discussed in relation to theories of phonological development, and may be used as a basis for further normative studies and ultimately the development of a contextually relevant Universityassessment of the phonology of Swahili speaking children. Key words: Swahili, speech, normative data, phonological development, phonetic inventory, Tanzania. iii TABLE OF CONTENTS PLAGIARISM DECLARATION ................................................................................................. i ACKNOWLEDGEMENTS......................................................................................................... ii ABSTRACT .............................................................................................................................. iii GLOSSARY OF TERMS............................................................................................................ x CONVENTIONS USED ............................................................................................................ xi LIST OF ABBREVIATIONS.................................................................................................... xii CHAPTER 1: INTRODUCTION ................................................................................................1 1.0 Introduction .......................................................................................................................1 1.2 Phonological assessment ....................................................................................................Town 3 1.3 General information on Swahili .........................................................................................6 1.3.1 Consonants ..................................................................................................................8 1.3.2 Vowels ........................................................................................................................Cape 8 1.3.3 Syllable structure .......................................................................................................10 1.3.4 Stress and Tone .........................................................................................................of 10 1.4 Previous studies on Swahili..............................................................................................10 1.5 Speech assessment and intervention in Tanzania ..............................................................11 1.6 The purpose of the study ..................................................................................................11 1.7 Overview of the study ......................................................................................................12 CHAPTER 2: LITERATUREUniversity REVIEW ................................................................................... 14 2.0 Introduction .....................................................................................................................14 2.1 Phonological development ...............................................................................................14 2.2 Phoneme acquisition ........................................................................................................18 2.3 Development of syllable Structures ..................................................................................23 2.4 Development of phonological processes...........................................................................24 2.5 PCC and PVC ..................................................................................................................27 2.6 Studies in African languages ............................................................................................28 2.7 Theoretical accounts of phonological acquisition .............................................................31 iv 2.7.1 Developmental Universals .........................................................................................31 2.7.2 Psycholinguistic frameworks .....................................................................................33
