The most important thing for the success of communication is the way people convey their meaning or ideas (Aamer Qureshi, 2013). The form of communication that is most used in daily life is conversation. Thus, speaking skill is considered as the main skill of communication (Aamer Qureshi, 2013; Srinivas Rao, 2019). Generally, speaking is an activity of pronouncing words, communicating verbally, conveying ideas and doing transaction (James, Yong, & Yunus, 2019; Leong & Ahmadi, 2017). Nurlaila and Paramitha adds that speaking is a part of daily life (Paramitha, 2016). However, speaking is the most difficult skill to be mastered (Srinivas Rao, 2019) because it is more spontaneous, chaotic, disorganized, informal, concise and clear rather than written language which is structured and coherent (Khalil, El-nagar, & Awad, 2019). Moreover, speaking is a complex activity involving all the linguistic elements such as pronunciation, grammar, vocabulary, fluency, and comprehension (Leong & Ahmadi, 2017). It means that a meaningful utterance should be right in the structure, diction, pronunciation, intonation, and context (James et al., 2019). The mistake in these linguistic elements may cause misunderstanding in communication.
