本文讨论了语音合成和语音识别在社会机器人中的作用和相关性。为了增加这项研究的一般性，一个人与一个和两个机器人执行任务时的相互作用被认为是。通过利用这些场景，将最先进的语音合成器与非语言话语进行比较（1）来自人类偏好和（2）机器人能力的感知，（3）将语音识别与键入文本进行比较，以输入关于用户偏好的命令，和（4）了解机器人的上下文的重要性和（5）合成语音获取这种上下文的作用进行了评估。语音合成和识别是不同的技术，但生成和理解语音应该被理解为同一口语现象的不同维度。此外，机器人上下文表示关于机器人正在执行的任务的操作条件和完成状态的所有信息。建立了两个用于在线实验的机器人装置。与第一个设置，只有一个机器人被雇用，我们的研究结果表明：高度自然的合成语音比蜂鸣声一样的音频首选;用户也更喜欢输入命令的声音，而不是通过键入文本;和，机器人的声音有一个更重要的影响感知机器人的能力比的可能性，通过语音输入命令。这里提出的分析表明，当用户与单个机器人进行交互时，其声音作为社交线索和人格化的原因失去了相关性，而进行交互，用户可以更好地评估机器人的能力，就其任务。在第二种设置的实验中，采用了两个机器人的协作试验台。当机器人在试图完成一项使命的同时相互交流以解决问题时，用户从更远的位置观察情况，“反射”视角占主导地位。我们的研究结果表明，获得机器人的上下文被认为是一个成功的人机合作，以完成给定的目标是必不可少的。为此，合成语音比屏幕上的文本更适合用于上下文获取。
The role and relevance of speech synthesis and speech recognition in social robotics is addressed in this paper. To increase the generality of this study, the interaction of a human being with one and two robots when executing tasks was considered. By making use of these scenarios, a state-of-the-art speech synthesizer was compared with non-linguistic utterances (1) from the human preference and (2) perception of the robots’ capabilities, (3) speech recognition was compared with typed text to input commands regarding the user preference, and (4) the importance of knowing the context of robots and (5) the role of synthetic voice to acquire this context were evaluated. Speech synthesis and recognition are different technologies but generating and understanding speech should be understood as different dimensions of the same spoken language phenomenon. Also, robot context denotes all the information about operating conditions and completeness status of the task that is being executed by the robot. Two robotic setups for online experiments were built. With the first setup, where only one robot was employed, our findings indicate that: highly natural synthetic speech is preferred over beep-like audio; users also prefer to enter commands by voice rather than by typing text; and, the robot voice has a more important effect on the perceived robot’s capability than the possibility to input commands by voice. The analysis presented here suggests that when the users interacted with a single robot, its voice as a social cue and cause of anthropomorphization lost relevance while the interaction was carried out and the users could evaluate better the robot’s capability with respect to its task. In the experiment with the second setup, a two-robot collaborative testbed was employed. When the robots communicated to each other to sort out the problems while they were trying to accomplish a mission, the user observed the situation from a more distanced position and the “reflective” perspective dominated. Our results indicate that to acquire the robots’ context was perceived as essential for a successful human–robot collaboration to accomplish a given objective. For this purpose, synthesized speech was preferred over text on a screen for context acquisition.
