Table 3  above  gives a list  of four  basic speech functions classes  and eight speech function response.
As  a  result,  in  a  conversation,  the  exchange  process  structure  and  speech functions  are  very  related  to  each  other.  It  realizes  the  role  relationship  of  the
speakers  to  each  other.  There  is  also  a  correlation  between  the  structure  of  a responding  move  and  the  different  structure  of  an  initiating  move.  By  looking  at
who  makes  what  kinds  of  moves  in  initiating  speech  function  and  identifying  the role  which  played  by  the  speakers,  we  can  explain  the  attitudes  toward  in  the
interaction, and it is called interpersonal role relationship.
2.4 Turn and Move in Casual Conversation
2.4.1.  Turn in Casual Conversation One of the implications of this is that the discourse patterns of speech function are
carried  not  by  grammatical  units,  such  as  the  clause,  but  by  a  discourse  unit,  a  unit sensitive to interactive function. The most obvious discourse unit is the turn on all the talk
produced by one speaker before another speaker gets in. It is very important units in casual talk or conversation.
Eggins  and  Slade  1997:  184  say  that  there  is  one  feature  of  turn  that  has  to  be mentioned  before  the  rules  can  be  presented,  namely  the  possibility  of  invited  to  speak
next. The turn can be described by the speakers in conversation by using speech function pairs. For examples:
1 a : i “Who wrote Laskar Pelangi?” question
2 b : i “Andrea Hirata.” answer
If  a  select  b in current turn for his question “who wrote Laskar pelangi?”, so
a  must stop speaking, and  b  must speak next by answering the a ‟s question.
1a D: i “I mean, ii the man love you.” 1b iii “I think, iv you must be happy marry with him.”
We can see that  D  is a single turn at talk. This change clearly indicates that D is making a number of moves in single turn, and expresses a statement. But, the moves are
still  in  one  meaning  of  D.  However,  the  turn  can  still  happen  even  when  the  hearer responses the speaker means of requests. For example, we can already point out that there
are the other speaker responses to D‟s first move, she is actually is a single turn:
2a S: i “I don‟t think so.” 2b ii “I just regard him as my friend.”
