In political communication, a speaker’s voice plays a crucial role, extending far beyond the content of their words. Often underestimated is how the voice reveals aspects of personality, such as determination in a firm tone or empathy in a soft delivery. As the 2024 U.S. elections approach, the focus on candidates’ personalities is once again at the forefront. “Big Five” personality model continues to provide insights into how openness, conscientiousness, extraversion, agreeableness, and emotional stability shape not only political behavior but also voter perceptions.

The Acoustic Analysis of Voice: Smiling and Laughter in Focus

At audEERING®, we specialize in the acoustic analysis of voices. One fascinating aspect of this is how smiling and laughter can significantly alter acoustic parameters. When someone smiles or laughs, formant frequencies (F1 and F2) increase, the fundamental frequency (F0) rises, and the voice becomes louder and more resonant. These acoustic signals play an essential role in how a speaker is perceived, particularly in high-stakes political environments.

As election season intensifies, candidates’ public appearances, interviews, and debates are scrutinized, not only for their content but for how they sound. Laughter, in particular, can become a focal point in political commentary.

Harris denounced by Trump

A notable example of how laughter is interpreted in politics can be seen with Vice President Kamala Harris. Throughout her time in office U.S. Vice President Kamala Harris was denounced by Donald Trump, who labeled her laughter as “crazy,” mocking her repeatedly as “laughing Kamala” to portray her laughter as a sign of insecurity or incompetence. This criticism is not just a personal attack but sheds light on deeper societal and political prejudices. Harris’ laughter has often been the subject of media attention and political critique. Yet, laughter is a multifaceted phenomenon, and its interpretation depends on both context and societal biases.

The coconut tree meme – context matters also in vocal perception

Interestingly, Harris’ laughter has also developed its cultural dynamic, manifested in social media and meme culture. A well-known example is the “coconut tree” meme, which went viral and depicts Harris in a moment of joyful spontaneity. This is based on a speech by Harris in which she refers to something her mother always said to make it clear that everything and everyone exists in context. She speaks of complexity with ease.

While supporters celebrate these moments as expressions of her authenticity, critics perceive them as signs of weakness or incompetence. Her laughter may play a role in making her appear more approachable and empathetic, although it can also evoke negative associations.

Overall, the debate around Kamala Harris’ laughter highlights the complexity of perceptions of leadership figures. It raises the question of how voices and their acoustic characteristics, such as laughter, convey emotional and political messages. Understanding and analyzing these aspects is of interest not only to political analysts but also to the general public, as they offer a deeper understanding of the subtle mechanisms of political communication.

Laughter as a Social Phenomenon in Politics

Studies show that laughter serves as a powerful social signal. It is often seen as a “costly” signal, meaning that it is difficult to fake and therefore conveys genuine emotion. In politics, this can strengthen perceptions of authenticity and social bonding. Laughter can help politicians connect with voters on an emotional level, fostering a sense of trust and relatability.

Research indicates that shared laughter—such as that between a politician and their audience—can create a sense of similarity and belonging, which is crucial during campaign events and speeches. In this election cycle, where personal connection and voter empathy may sway undecided voters, understanding the acoustic and emotional impact of a candidate’s voice has never been more relevant.

Laughter as a Social Bond

A study shows that shared laughter strengthens the sense of connection between people. This research suggests that shared laughter, as opposed to solitary joy, plays a more significant role in relationship maintenance. It creates a sense of similarity and belonging, which is particularly important in political contexts, where building trust and sympathy is crucial.
