What Does Your Voice Reveal About You?
Trait Activation of Voice Characteristics and Their Relation With Personality and Communication Styles
Abstract
Abstract. The first goal of the present study was to explore how 21 voice measures related to self-reported personality and communication styles. The second goal was to test the assertion of Trait Activation Theory (TAT) that traits are activated in relevant situations and that verbal behavior is the result of an interplay between individual differences and situations. The voice of 138 participants was measured in the lab via steady voice and continuous speech tasks, whereas personality and communication styles were self-reported using the HEXACO and Communication Styles Inventory. To test TAT, four scenarios were developed to activate the communication styles of Informality and Expressiveness. It was hypothesized that the activated communication styles will interact with relevant situations and will be expressed through changes in voice (i.e., pitch variation). Regarding the first goal, an explorative approach revealed that voice characteristics are informative mainly for the personality traits of Openness to Experience, Emotionality, and Conscientiousness and the communication styles of Emotionality and Questioningness. Regarding the second goal, the interactions between situations and communication styles provided mixed support for TAT. Implications and limitations of the study are discussed.
