A linguistic phenomenon in which an oral statement contains many words, but little or no semantic information is conveyed. It is often characterized by vague statements, excessive use of clichés, vague references, and a lack of specific details or meaningful content. Empty speech can occur in different situations, for example, in people with certain forms of aphasia (for example, Wernicke’s aphasia), when fluency and grammar of speech are preserved, but semantic completeness is impaired. It can also be observed in mental disorders, cognitive decline, or as a special style of communication in which the speaker avoids meaningful information. In clinical practice, the identification of empty speech is important for the diagnosis of hidden neurological or psychological disorders.
