This study intends to investigate the type and the frequency of direct and indirect speech act represented in the dialogues of English textbook for senior high school grade XI published by team Masmedia Buana Pustaka. In doing so, a number of fifteen dialogues from five units of the textbook were chosen purposively and analyzed by using Searle’s pragmatics model. The content analysis was applied as a means to find out and investigate the type as well as the frequency of direct and indirect speech act. The result of coding and categorizing of the dialogues showed that there were several main categories of Searle’s type of speech act had been used; the assertive, commissive, directive, expressive and indirect speech act. The division of labor of these categories indicated that the assertive speech was found to have been used 39 %, the directive speech act got the maximum share of 34.8 % and the expressive was employed 11.9 %. Meanwhile, the commissive speech act, one of crucial speech categories was identified 3.7 % distributed in the all selected dialogues. The indirect speech act was found 10.8 % shared in the assertive, commissive and directive class. Of these categories, the direct speech acts were used more frequently than that of the indirect. This work revealed that specific type of speech act has been employed and distributed unequally throughout the textbook dialogues. On the basis of these findings, the textbook writers and English EFL teachers are recommended that the balancing of the types and the frequencies of speech act be considered and included in current English textbook’s dialogues.
