In this paper, we present a demo of an intelligent personal agent called Hey Dona (or just Dona) with virtual voice assistance in student course registration. It is a deployed project in the theme of AI for education. In this digital age with a myriad of smart devices, users often delegate tasks to agents. While pointing and clicking supersedes the erstwhile command-typing, modern devices allow users to speak commands for agents to execute tasks, enhancing speed and convenience. In line with this progress, Dona is an intelligent agent catering to student needs by automated, voice-operated course registration, spanning a multitude of accents, entailing task planning optimization, with some language translation as needed. Dona accepts voice input by microphone (Bluetooth, wired microphone), converts human voice to computer understandable language, performs query processing as per user commands, connects with the Web to search for answers, models task dependencies, imbibes quality control, and conveys output by speaking to users as well as displaying text, thus enabling human-AI interaction by speech cum text. It is meant to work seamlessly on desktops, smartphones etc. and in indoor as well as outdoor settings. To the best of our knowledge, Dona is among the first of its kind as an intelligent personal agent for voice assistance in student course registration. Due to its ubiquitous access for educational needs, Dona directly impacts AI for education. It makes a broader impact on smart city characteristics of smart living and smart people due to its contributions to providing benefits for new ways of living and assisting 21st century education, respectively.

翻译：本文展示了一个名为“嘿，多娜”（简称多娜）的智能个人代理演示，该代理通过虚拟语音辅助实现学生课程注册。它是一个已部署的项目，主题是人工智能赋能教育。在这个充满智能设备的数字化时代，用户常将任务委托给代理。虽然点击操作已取代了早期的命令输入，但现代设备允许用户通过语音指令让代理执行任务，从而提升速度与便利性。顺应这一趋势，多娜作为智能代理，通过自动化的语音操作课程注册来满足学生需求，支持多种口音，涉及任务规划优化，并在必要时进行语言翻译。多娜通过麦克风（蓝牙、有线麦克风）接收语音输入，将人类语音转换为计算机可理解的语言，根据用户指令进行查询处理，连接网络搜索答案，建模任务依赖关系，实施质量控制，并通过语音和文本显示向用户输出结果，从而实现语音与文本结合的人机交互。它旨在无缝运行于台式机、智能手机等设备上，并适用于室内和室外环境。据我们所知，多娜是首批用于学生课程注册语音辅助的智能个人代理之一。由于其面向教育需求的普适性，多娜直接影响了人工智能赋能教育。它通过为新型生活方式提供便利并助力21世纪教育，分别对智慧城市中智慧生活与智慧人群的特征产生了更广泛的影响。
