MORE EXAMPLES: "It also possesses a sense that humans lack." (Use "aye" to get your point across to the listener. "Uh" would be incorrect, as it doesn't highlight "a sense" and thus would lose most listeners.)

Use either AYE or UH depending on which best allows your listener to comprehend what you're saying and meaning. EXAMPLE 1: "We have "uh" post office that has "aye" pretty talented dog delivering the mail." EXAMPLE 2: "We have "uh" pretty talented dog that works at "aye" post office delivering the mail.
