随着人机协作机会的不断扩大，信任对于机器人的充分参与和利用变得越来越重要。建立在情感关系和人际关系基础上的情感信任尤其重要，因为它对错误更有弹性，并增加了合作的意愿。在本文中，我们提出了一种新的模型，建立在音乐驱动的情感韵律和手势，鼓励感知的机器人身份，旨在避免恐怖谷。人类音乐家生成了具有象征意义的乐句，并标记了情感信息。这些短语控制着一个合成引擎，播放通过音素和电子乐器插值生成的预渲染音频样本。手势也是由象征性的短语驱动的，从音乐短语到低自由度的动作都编码了情感。通过用户研究，我们表明我们的系统能够准确地向用户描绘一系列情绪。我们还展示了一个显著的结果，即我们的非语言音频生成比使用最先进的文本到语音系统的平均信任度高出8%。
As human-robot collaboration opportunities continue to expand, trust becomes ever more important for full engagement and utilization of robots. Affective trust, built on emotional relationship and interpersonal bonds is particularly critical as it is more resilient to mistakes and increases the willingness to collaborate. In this paper we present a novel model built on music-driven emotional prosody and gestures that encourages the perception of a robotic identity, designed to avoid uncanny valley. Symbolic musical phrases were generated and tagged with emotional information by human musicians. These phrases controlled a synthesis engine playing back pre-rendered audio samples generated through interpolation of phonemes and electronic instruments. Gestures were also driven by the symbolic phrases, encoding the emotion from the musical phrase to low degree-of-freedom movements. Through a user study we showed that our system was able to accurately portray a range of emotions to the user. We also showed with a significant result that our non-linguistic audio generation achieved an 8% higher mean of average trust than using a state-of-the-art text-to-speech system.
