• Title: Robotic Speech Synthesis: Perspectives on Interactions, Scenarios, and Ethics
• Authors: Yuanchao Li, Catherine Lai
• Abstract summary: We discuss the difficulties of synthesizing non-verbal and interaction-oriented speech signals, particularly backchannels. We present the findings of relevant literature and our prior work, trying to bring the attention of human-robot interaction researchers to design better conversational robots.

• Abstract: In recent years, many works have investigated the feasibility of conversational robots for performing specific tasks, such as healthcare and interview. Along with this development comes a practical issue: how should we synthesize robotic voices to meet the needs of different situations? In this paper, we discuss this issue from three perspectives: 1) the difficulties of synthesizing non-verbal and interaction-oriented speech signals, particularly backchannels; 2) the scenario classification for robotic voice synthesis; 3) the ethical issues regarding the design of robot voice for its emotion and identity. We present the findings of relevant literature and our prior work, trying to bring the attention of human-robot interaction researchers to design better conversational robots in the future.

  The ability to interact with machines using natural human language is becoming commonplace, but expected. In this paper, we chronicle the recent history of this growing field of spoken dialogue with robots. We offer the community three proposals, the first focused on education, the second on benchmarks, and the third on the modeling of language when it comes to spoken interaction with robots.

  We introduce a fully-automated conversation system that leverages large language models (LLMs) to generate robot responses with expressive behaviors. We conduct a pilot study where volunteers chat with a social robot using our proposed system, and we analyze their feedback, conducting a rigorous error analysis of chat transcripts. Most negative feedback was due to automatic speech recognition (ASR) errors which had limited impact on conversations.

  We design and label four types of empathetic non-verbal cues, abbreviated as SAFE: Speech, Action (gesture), Facial expression, and Emotion, in a social robot. Preliminary results show distinct patterns in the robot's responses, such as a preference for calm and positive social emotions like 'joy' and 'lively', and frequent nodding gestures. Our work lays the groundwork for future studies on human-robot interactions, emphasizing the essential role of both verbal and non-verbal cues in creating social and empathetic robots.

  Partial subtle mirroring of nonverbal behaviors during conversations (also known as mimicking or parallel empathy) is essential for rapport building. Our research question is whether integrating an ECA able to mirror its interlocutor's facial expressions and head movements with a human-service robot will improve the user's experience. Our contribution is the complex integration of an expressive ECA, able to track its interlocutor's face, and to mirror his/her facial expressions and head movements in real time, integrated with a human support robot.

Results show that the generated explanations of our approach significantly improves the collaboration performance and user perception of the robot.
