“…The parameters that offer a more evident interpretation indicate that a calm advertisement style was characterized by lower pitch (lower f 0 ), quieter voice (lower loudness, smaller mean alpha ratio), with no abrupt changes in loudness (smaller rising and falling slopes of loudness), and a sonorous voice (less steep spectral slope). The calm advertising style was also characterized by a more neutral rather than an emotional performance (see Liu and Xu, 2014;Pralus et al, 2019;Voße et al, 2022; lower spectral flux, lower f 0 , bigger rising slope f 0 , and smaller falling slope of f 0 , higher Hammarberg index), and the calm style is also differentiated from the energetic by parameters related to timbre (higher MFCC 2 , MFCC 3 , MFCC 4 , see Nordström, 2019, p. 27). See Figure 3.…”

The increasing prevalence of audio advertising has provided a challenge to find out more about voices and performance styles used in advertisements. In this study, we were interested in the listeners' preferences when a synthesizer performs the advertisements. As training an advertisement style synthesizer requires big corpora, the creation of which is time-consuming and expensive, we have chosen to use less resource-intensive style transfer on already extant synthesized voices trained on neutral speech. We used a corpus of advertisements created out of 120 male and 120 female voices reading one text in both an energetic and calm advertisement style, the styles most commonly provided by advertising agencies, to train four style transfer models: energetic and calm for both male and female voices. These were used to convert two synthesized female and two male voices that had been created using a Merlin-based speech synthesizer for Estonian. Each converted voice performed three short advertisements. Adult listeners rated the likability of the performances on a 7-point Likert scale. The results showed that the calm performance style was overwhelmingly preferred. We also ascertained the acoustic features of the calm and energetic performances using the open-source toolkit openSMILE to calculate the 88 parameters of the extended Geneva Minimalistic Acoustic Parameter Set. The calm style differed from the energetic in acoustic features that are related to a lower, quieter, and more sonorous voice and a more neutral speaking style. Considering the difference in style ratings, it is worth taking the target audiences' style preferences into account.

“…Voice quality-such as modal, creaky, or breathy voicecontributes to perceived personality traits and by that, to perceived charisma of the speakers; see Voße et al (2022) and Pearsell and Pape (2023). Yet, Bono and Judge (2004) assume rather weak associations between the big five personality traits and charisma.…”

Charisma is considered as one's ability to attract and potentially influence others. Clearly, there can be considerable interest from an artificial intelligence's (AI) perspective to provide it with such skill. Beyond, a plethora of use cases opens up for computational measurement of human charisma, such as for tutoring humans in the acquisition of charisma, mediating human-to-human conversation, or identifying charismatic individuals in big social data. While charisma is a subject of research in its own right, a number of models exist that base it on various “pillars,” that is, dimensions, often following the idea that charisma is given if someone could and would help others. Examples of such pillars, therefore, include influence (could help) and affability (would help) in scientific studies, or power (could help), presence, and warmth (both would help) as a popular concept. Modeling high levels in these dimensions, i. e., high influence and high affability, or high power, presence, and warmth for charismatic AI of the future, e. g., for humanoid robots or virtual agents, seems accomplishable. Beyond, also automatic measurement appears quite feasible with the recent advances in the related fields of Affective Computing and Social Signal Processing. Here, we therefore present a brick by brick blueprint for building machines that can appear charismatic, but also analyse the charisma of others. We first approach the topic very broadly and discuss how the foundation of charisma is defined from a psychological perspective. Throughout the manuscript, the building blocks (bricks) then become more specific and provide concrete groundwork for capturing charisma through artificial intelligence (AI). Following the introduction of the concept of charisma, we switch to charisma in spoken language as an exemplary modality that is essential for human-human and human-computer conversations. The computational perspective then deals with the recognition and generation of charismatic behavior by AI. This includes an overview of the state of play in the field and the aforementioned blueprint. We then list exemplary use cases of computational charismatic skills. The building blocks of application domains and ethics conclude the article.
