- Changes in the pitch of their voice, either lower and slower, or higher and faster
- Changes in the speed of their speech

- Attempting to distract you by interrupting your conversation
- Unusual choice of words or sentence structure
- Stalling the conversation with pauses, and “um”, “you know”, and “well…”
- Emphasizing the word “not” when talking
