A Yellow’s tone of voice denotes a strong commitment from start to finish. You hear it from afar: Laughter, fun, intensity. Enthusiasm. Joy. Energy. Generally speaking, Yellows show empathy very clearly. They’re with you either 100 percent or not at all. And this can be heard in their voice. It goes up and down; it changes tempo, vigor, and intensity. Yellows often have a powerful melody in their way of speaking. No matter what emotion has seized the Yellow at the moment, it will be noticeable in his voice.
