If you hold your hand up signifying your wish to speak, your nonverbal communication is regulating your verbal interaction.

Explanation:

Regulating verbal interaction refers to the non-verbal language we use to express our intention to speak or to regulate the speech of other people, in order to express our ideas, thoughts, attitudes, etc.

This process is a part of the nonverbal cues we use to regulate interaction and express our verbal intentions. For example, if the teacher says something and then asks a class to express their opinion about it, you will raise your hand to show your intention to speak and express your opinion.
