Muttering is a form of speech characterized by low, indistinct, or unclear sounds. It often occurs when a person is speaking softly or under their breath, making it difficult for others to hear or understand what is being said. This behavior can be a response to various emotions, such as frustration, annoyance, or embarrassment, and may serve as a way to express feelings without drawing attention. In social situations, muttering can lead to misunderstandings, as listeners may misinterpret the speaker's intent or content. It is commonly observed in everyday life, such as during conversations, lectures, or even while reading aloud. Understanding the context and tone of muttering can help clarify communication.
