The correct response is communication roadblocks.
Communication roadblocks can include various barriers that affect the listener or speaker, such as misunderstandings, biases, emotional states, distractions, and attention issues. Hearing impairments and speech impairments can also be specific types of roadblocks, but "communication roadblocks" is a broader term that encompasses a wide range of barriers in communication. Verbal disagreements are also a form of roadblock but are more specific to conflicts in dialogue rather than general communication barriers.
