“…However, since this experiment used two different human-like appearances, it is necessary to consider the influence of anthropomorphism. Anthropomorphism can affect interaction with humans and can affect trust [ 41 , 70 , 71 ].…”

As AI technologies progress, social acceptance of AI agents, including intelligent virtual agents and robots, is becoming even more important for more applications of AI in human society. One way to improve the relationship between humans and anthropomorphic agents is to have humans empathize with the agents. By empathizing, humans act positively and kindly toward agents, which makes it easier for them to accept the agents. In this study, we focus on self-disclosure from agents to humans in order to increase empathy felt by humans toward anthropomorphic agents. We experimentally investigate the possibility that self-disclosure from an agent facilitates human empathy. We formulate hypotheses and experimentally analyze and discuss the conditions in which humans have more empathy toward agents. Experiments were conducted with a three-way mixed plan, and the factors were the agents’ appearance (human, robot), self-disclosure (high-relevance self-disclosure, low-relevance self-disclosure, no self-disclosure), and empathy before/after a video stimulus. An analysis of variance (ANOVA) was performed using data from 918 participants. We found that the appearance factor did not have a main effect, and self-disclosure that was highly relevant to the scenario used facilitated more human empathy with a statistically significant difference. We also found that no self-disclosure suppressed empathy. These results support our hypotheses. This study reveals that self-disclosure represents an important characteristic of anthropomorphic agents which helps humans to accept them.

“…Our findings also indicate the need for speech synthesizers to be able to produce utterances with varying degrees of breathiness in varying positions, an ability which exists for HMMbased TTS [35] but it is yet to be added to state-of-the-art neural synthesizers. For example, effective spoken-language interaction with robots [36] will likely need this: to be able to distinctively produce both self talk [37], intended to unobtrusively give status updates to the user, and user-directed talk, needing im-mediate attention; and also able to clearly distinguish between the activity of establishing common ground and the activities of drawing conclusions and reaching decisions, for the sake of effectively coordinating joint action [38].…”

Although the paralinguistic and phonological significance of breathy voice is well known, its pragmatic roles have been little studied. We report a systematic exploration of the pragmatic functions of breathy voice in American English, using a small corpus of casual conversations, using the Cepstral Peak Prominence Smoothed measure as an indicator of breathy voice, and using a common workflow to find prosodic constructions and identify their meanings. We found two prosodic constructions involving breathy voice. The first involves a short region of breathy voice in the midst of a region of low pitch, functioning to mark self-directed speech. The second involves breathy voice over several seconds, combined with a moment of wider pitch range leading to a high pitch over about a second, functioning to mark an attempt to establish common ground. These interpretations were confirmed by a perception experiment.

“…Suggestive results were also obtained in passing the mirror test: inner speech enables a conceptual reasoning for inferring the identity of the reflected entity in a mirror, and robot becomes able to recognize itself [ 8 ]. In a previous paper [ 9 ], we argued that robot’s inner speech might act as a facilitator for human understanding and predicting the robot behaviors, as they form adequate mental representation of the robot. As a matter of fact, mind perceptions consist of two core dimensions: (1) agency, e.g.…”

Inner Speech is an essential but also elusive human psychological process that refers to an everyday covert internal conversation with oneself. We argued that programming a robot with an overt self-talk system that simulates human inner speech could enhance both human trust and users’ perception of robot’s anthropomorphism, animacy, likeability, intelligence and safety. For this reason, we planned a pre-test/post-test control group design. Participants were divided in two different groups, one experimental group and one control group. Participants in the experimental group interacted with the robot Pepper equipped with an over inner speech system whereas participants in the control group interacted with the robot that produces only outer speech. Before and after the interaction, both groups of participants were requested to complete some questionnaires about inner speech and trust. Results showed differences between participants’ pretest and post-test assessment responses, suggesting that the robot’s inner speech influences in participants of experimental group the perceptions of animacy and intelligence in robot. Implications for these results are discussed.
