【正确答案】The three related acts are: LOCUTIONARY ACT, ILLOCUTIONARY ATC, PERLOCUTIONARY ACT.
LOCUTIONARY ACT is the ordinary act we perform when we speak, i.e. we move our vocal organs and produce a number of sounds, organized in a certain way and with a certain meaning.
ILLOCUTIONARY ATC is the act performed in the performing of a locutionary act. When we speak we not only produce some units of language with certain meanings, but also make clear our purpose in producing them, the way we intend them to be understood, or they also have certain forces as Austin prefers to say.
PERLOCUTIONARY ACT concerns the consequential effects of a locution upon the hearer. By telling somebody something the speaker may change the opinion of the hearer on something, or mislead him, or surprise him, or induce him to do something, etc. whether or not these effects are intended by the speaker, they can be regarded as part of the act that the speaker has performed.
Customer: The locutionary act of the customer is the uttering of the expression "Waiter! There's a fly in my soup". The illocutionary act is the expression of the customer's dissatisfaction with the service and the demand that the waiter should apologize and offer another bowl of soup. The perlocutionary act of this utterance is the waiter apology and offering of another bowl of soup.
Waiter: The locutionary act of the waiter is the uttering of the expression "Don't worry, there's no extra charge". The illocutionary act is the literary meaning of his response: Don't worry and we will not charge you extra money for the fly, but we will not get you another bowl of clean soup. The perlocutionary act is that the customer will not complain any more.
