It could also hope to provide possible solutions or directions to take into account or at the very least mitigate these problems for EFL students on their process of becoming future fluent English speakers. A survey was conducted on 43 EFL students ranging from freshmen to seniors at Can Tho University (CTU) in order to identify the cores of their problems with suitable solutions to speaking English better. The results showed that the primary cause leading to unfluent speeches in English was the lack of vocabulary needed to convey thoughts and ideas. Fortunately, the key to solving this problem was quite simple and could be applied to every EFL students at any level to have better speaking skills. Based on the findings, the solutions were to be an increase interaction with the language itself and also the improvement of other essential English skills. Also, these solutions could be practiced by EFL students themselves or with the help of English instructors and teachers from various educational institutions.
