A Comparative Study of the Sound Systems of Ikwo Igbo and Standard Igbo Dialects Ngozi Uka Ukpai Department of Languages and Linguistics Alex Ekwueme Federal University Ndufu-Alike Ebonyi State, Nigeria. Email: [email protected] ABSTRACT Development is often associated with challenges. The inability to study the numerous available dialects of Igbo language is one of the identified challenges facing the development of Igbo language particularly in the area of Igbo language teaching and learning, structural development of Igbo language, computation, and reconciliation of Igbo language with Information and Communication Technologies. Therefore, there is need to study the varying dialects of Igbo language before we can set a standard structure for the language which will facilitate a better teaching and learning of Igbo language, and harness the reconciliation of Igbo language with information and communication technologies. The present study investigated the structural differences between the sound system of Ikwo Igbo and Standard Igbo dialects. Descriptive research design was adopted for this work. However, it was largely discussed focusing on an aspect of generative phonology called feature theory. From this research, we discovered that the sound system of the two dialects are the same, except that while standard Igbo has thirty-six (36) phonemes; comprising eight (8) vowels and twenty-eight (28) consonants, the Ikwo dialect has forty-five (45) phonemes; comprising nine (9) vowels and thirty-six (36) consonants. It was observed that the sounds /s/ and /z/ cannot occur before /i/ or /ị/ in Ikwo dialect, rather /s/ and /z/ changes their forms to [ʃ] and [ʒ] respectively when the high front vowels [i] or [ɪ] is occurring after them. Vowel sounds occurring at utterance final positions in Ikwo dialect is usually elided as utterances are ended more abruptly than in Standard Igbo. Whereas certain phonemes occur in some environments in Standard Igbo, they assume different forms in Ikwo dialect. Apart from these differences, other features of Ikwo dialect, including the tonal structure corresponds with the Standard Igbo dialect sound system. Keywords: minimal pairs, contrastive distribution, complementary distribution, language, dialect, phonemes INTRODUCTION The linguistic diversity dominant in Igbo linguistic similarity with other region led to the development of a neighboring dialects like; Izhi, Ezza, Standard Igbo variety to help unify the Ezzamgbo, Ohaozara, and other Abakaliki speakers of the different dialects of Igbo dialects. Ikwo is bounded to the east and language. Igbo language is classified as south by the Cross river state, west by the one of the languages of New Benue-Congo Ezza south local government area, and under the Niger-Congo family [1]. Ikwo is north by the Abakaliki local government one of the dialects of Igbo language area of Ebonyi state (Izhi), [2]. spoken in Ikwo local government area of Currently, Ikwo local government area has Ebonyi state, Nigeria. It is important to been divided into six (6) developmental know that Ikwo dialect shares certain centers which include: Ikwo south, 41 IDOSR JOURNAL OF HUMANITIES AND SOCIAL SCIENCES 5(1): 41-57, 2020. www.idosr.org Ukpai central, East, south-east, Ndufu Ikwo, and are both offshoots of structural grammar Ikwo development centers.

Of course, the Igbo divisional zones are; Ụnwẹka zone (it language will not be exempted from this. comprises three communities), Alike zone We are quite aware that a number of (comprises of four communities), Ẹchara persons have been working tremendously zone (comprises two communities), to reconcile the Igbo language with Mgbabụ zone (has six communities), developing technologies (an aspect known Ọkpitumo zone (has two communities). as computational linguistics), but because A white man, Meier organized a team of of certain challenges which have been left Ikwo speakers like; Elder Thomas Uzim, unresolved, these woks have many flaws. Mr. Elias Uguru, and Mr. William Akichi Therefore, to overcome these challenges and collected word lists in Ikwo, from and promote the development of Igbo which, they developed orthography for language there is need to study and writing the Ikwo dialect in 1972. During identify the structure of every dialect of this period, they translated lot of books Igbo language, beginning from the sound from English to Ikwo. Example; they structure to syntactic structure, from translated the holy bible to Ikwo dialect. such study we can set a standard for Igbo They also wrote series of texts in Ikwo language.
