1.1 BACKGROUND OF THE STUDY
Language in any human society is an important human heritage. The significance of language in human life cannot be over-emphasized. It is indeed central not only to our social interactions and relationships, but also in distinguishing us and enabling others to ascertain the position in the society. This would explain why people with speech or hearing disabilities find it difficult to integrate and participate fully in their communities. What this means is that every language community has developed unique modes of using its language. At the same time, each language has been moulded in a special way to serve the needs of the community that speaks it. In this way, every language is a unique system and therefore, a resource for humankind. It is because of the many unique systems in each language that we talk of linguistic diversity. This linguistic diversity, like bio-diversity, is an important feature of our universe. The many languages spoken by the various world populations signify the communication problems, which human societies are likely to face in their day to day interactions.
