In this era of technology, it is believed that English language learning has made more accessible and easier for those who are interested to learn it. Part of utilizing this technology includes using a smart phone, not only for social communication purposes but also for learning. One of the applications used for learning in this regard is Viber which can be installed on cell phones for people communicate not only individually but in group. This may be considered as an important tool for language learning, as a cell phone opens a gate for downloading, uploading and storing learning materials and information files.
This study attempts to explore the use of Viber in developing vocabulary skills during group chat among university learners at St. Mary’s University in Ethiopia. Twenty undergraduate students taking ‘Sophomore English Course’ at the University were selected using simple random sampling as objects of the study. They were interviewed and focus group discussion was held to find out if Viber helped them to enhance their vocabulary skills. The findings show that the use of Viber can enable students to develop their vocabulary skills through a lifelong and informal activity, though some words may be spelt incorrectly and the communication could be full of abbreviations and acronyms. The study recommends that university teachers can use this application, in a controlled manner, to help their students improve their vocabulary skills, and may give them assignments for further practice outside of their classrooms.
