What is when a guy softens his voice?

There could be several reasons why a guy softens his voice. Here are a few possibilities:

1. Attraction - When a guy is attracted to someone, he may naturally soften his voice to come off as more gentle and approachable.

2. Comfort - When someone is feeling uncomfortable or uncertain in a situation, they may soften their voice as a way to ease tension or create a more relaxed atmosphere.

3. Empathy - Softening one's voice can also be a way of expressing empathy and understanding towards someone else's feelings or situation.

4. Control - Some people may soften their voice when they're trying to assert control in a situation, using a quieter tone to draw others in and make them listen more closely.

Ultimately, the reasons for softening one's voice can vary depending on the individual and the situation, so it's important to pay attention to other cues (such as body language and facial expressions) to get a full sense of what someone is communicating.
