 +**Acoustic characteristics of the charismatic voice**
 +
 +In this talk I will present my research on the charismatic voice in the context of political leadership. The general hypothesis is that the speaker-leader uses his/her voice based on two functions. These functions are employed in order to persuade an audience and achieve certain goals.
 +
 +The primary function is biological and consists of manipulating changes in fundamental frequency in order to be recognized as the leader of the group. Results show that if the speaker-leader wants to submit group members and hopes to appear as a dominant or threatening leader, the leader uses a low fundamental frequency associated with phonatory types such as creaky voice. If he wants to be perceived as a sincere, calm, and reassuring, he uses a higher fundamental frequency associated with his modal voice, avoiding phonatory types such as harsh voice.
 +
 +The secondary function of the charismatic voice is learned and dependent upon the language spoken and the culture that one belongs to, and consists of changing voice quality in order to convey different traits and types of charisma. The use of one's voice quality for conveying different types of charisma, as characterized by varying attributes, is filtered through the language and culture that favor certain charismatic vocal behaviors which serve as prototypes that correspond to the audience's inherent expectations.
 +
 +During the talk I will present some experimental studies that establish an acoustic and perceptual description of the charismatic voice. Speech range profiles  show interesting cross-language and cross-cultural similarities in leaders' vocal behavior. Analysis of voice quality combined to perceptual tests demonstrate the influence of voice acoustic parameters on the perception of different types and attributes of charismatic leadership.
