This study tries to describe the phonological developments noted in Sidaamu Afoornspeaking children. The research took a descriptive design, employing perceptual phoneticrnand phonological analysis. Data was collected from 6 children aged between 3; 6 and 5; 0rnyears. The data were collected by having the children repeat lists of single-words andrnsentences. The repetition tasks were supplemented by pictures describing the words andrnsentences that the children were supposed to say following the research's utterances.rnSpontaneous continuous speech were also recorded by having the children tell stories,rnnarrate activities, etc. SONY digital tape and video recorders were employed to capturernaudio and video signals, as the chi ldren talk. Data collection was carried out in tworndomains: at home and school. The data were first recorded orthographically and thenrntranscribed using IP A and ExtIP A, when deemed necessary.rnThe data were first analyzed individual ly, i.e., evclY child's phonological profile wasrnanalyzed and presented as separate case studies. The common speech production featuresrnwere grouped together and presented as summaries of the phonological processes attestedrnin the children. Attempts were also made to compare the results of the present study withrnother reports in the literature.rnThe findi ngs of this study showed that although most of patterns of phonologicalrndcvclopmcnts observed in Sidaamu Afoo speaking children are also common in otherrnlanguages, there are still some language specific features that are particular tG individualrnlanguages. These differences mainly arise from the fact that languages differ in theirrnphonemic inventories, phonotactic tules, and even overall phonological systems. Anrnexample of language specific-feature noted in Sidaamu-Afoo speaking chi ldren, i.e.,rnfeature not reported for other languages, is the ejectivisation of the implosive /efl, i.e.,rnrealization of /efl as [1']. This pattern was noted in most of the children, implying that,rnalthough ejectives and implosives are both glotta lic sounds, ejecti visation appears to berneas ier for children to acquire first than implosives. This relates to the additionalrnphysiological efforts and aerodynamic complexity that implosives require to be produced.rnThi s study is by no means complete and conclusive and in fact suffers fromrngeneralizations and shallow analysis. It is just an attempt to describe an aspect of thernphonological development of the children in question. But, it is hoped that the study canrnbe a preliminary ground for fu rther research to build up on.
