The document discusses three types of speech acts: locutionary acts, which refer to the actual utterance and its literal meaning; illocutionary acts, which refer to the intended significance or pragmatic force behind an utterance; and perlocutionary acts, which refer to the consequences or effects of an utterance on the listener. Locutionary acts correspond to the verbal, syntactic, and semantic aspects of an utterance. Illocutionary acts represent the socially valid purpose of an utterance. Perlocutionary acts view a speech act in terms of its effects on the listener, such as persuading or inspiring them.
