The reader will discover how the vocal production system in particular is dependent on the physiological parameters modulated by individual emotional state. The perceived emotional valence of being happy, sad, angry, or afraid is discussed in the gender context. Acoustic specialization of the two hemispheres of the brain is presented, and the role of the brain in regulating specific vocal emotions is reviewed. Vocalization patterns thought to help us in sexual behavior including mate choices and the role voice plays in our intimate behavior are discussed.
