Nervous speech fillers, also known as ERS, are words or phrases that people use to fill pauses in their speech when they are feeling anxious. They are often used to give the speaker more time to think of what to say next. Examples of common nervous speech fillers include 'um, ' 'uh, ' and 'LIKE.' These fillers can be distracting and can make it difficult for the listener to understand the speaker's message.
