Idiolalia refers to the use of speech that is unintelligible to others. However, there are a few synonyms that can be used instead of using idiolalia. For instance, gobbledygook means that the language used is confusing and makes no sense. Incoherence is another term used to describe when speech is difficult to comprehend, and Asemic writing refers to any communication that is incomplete or illegible. Similarly, babbling is when one speaks in an incoherent and unintelligible manner, while garble means speech or communication that is confused or distorted. Finally, Jargon refers to a specialized language that may be difficult for others to understand, while murmur means speaking in a soft, barely audible tone, making the words indistinct and incoherent.
