The purpose of this study is to enhance senior citizens’ speaking performance through the integration of an AI voice chatbot (Speak and Toko). Additionally, this study will focus on whether senior learners’ motivation can be improved. The participants consist of twenty individuals at retirement age (around or above 65) who have some background in English learning. A recruitment test will be conducted to show their proficiency level. Pre- and post-tests will be conducted before and after the experiment to evaluate whether learners show significant improvement following the intervention. Their answer will be recorded and analyzed. Fluency, accuracy, and delivery are the key criteria in the evaluating chart. After the tests, a thoroughly designed questionnaire will be administered to the senior adults to gather their opinions on learning with the assistance of the AI voice chatbot. The questions aim to explore the relationship between this new learning method and learners’ motivation. Motivation will be measured based on Expectancy-Value Theory, Maslow’s Hierarchy of Needs, and Gardner’s Model.
