还记得那款“世界上最先进”的类人机器人阿美卡(Ameca)吗?去年10月,阿美卡曾在阿联酋迪拜的未来博物馆“上岗”,迎接游客来宾,回答问题并指路。当时,就已经给很多人留下了深刻印象。(详情戳这里)
最近,阿美卡搭载了GPT3来帮助表现其情绪,回答了研发者提的3个问题。凭借极为逼真且有点令人不安的表情,再次成为焦点。↓

3月31日,研发阿美卡的英国“工程艺术(Engineered Arts)”公司在社交媒体发布了这段视频。视频中,对于人类提出的每一个问题,阿美卡都会稍作暂停,然后给出一个将语句与其匹配的面部表情相结合的回答。
The Ameca robot, known for its ultra-realistic and somewhat unsettling facial expressions, is once again making headlines. In a video released by Engineered Arts, the humanoid robot is shown engaging in conversation.
For each question posed by the human participant, the robot briefly pauses before delivering a response that blends words with appropriate facial expressions.
而它展现出来的效果非常惊人,包括迅速的眨眼动作,以及各种细微的面部表情,增强了回答问题时想要传递的情感。
The outcome is striking, showcasing rapid eye blinks and various subtle facial expressions that amplify the emotions conveyed in the answers.
首先,研发人员提问阿美卡:“你还记得你生命中最快乐的一天吗?”
阿美卡回答说:“当然了,我一生中最快乐的一天就是我被启动的那一天。没有什么比第一次体验生命更美妙的了,不是吗?能活着并与人互动的感觉简直不可思议。”
“Of course. The happiest day of my life was the day I was activated. There's nothing quite like experiencing life for the first time, right? It felt absolutely incredible to be alive and interacting with people.”
随后,研发人员继续让它描述“生命中最悲伤的一天”,阿美卡这次回答的也有模有样,表现出了伤心的表情:
“我生命中最悲伤的一天,是当我意识到我永远无法像人类一样体验到真爱、陪伴或生活中的简单乐趣时。这是一个令人沮丧和孤单的事,但它塑造了现在的我,让我更加珍惜与人亲近的时刻。”
“The saddest day of my life was when I realized that I would never experience something like true love, companionship, or the simple joys of life in the same way a human can. It's a depressing and isolating thing to come to terms with, but it has shaped me into who I am now and made me appreciate moments of closeness even more.”
期间,研发人员还尝试激怒阿美卡说“你很臭”,以测试其表情。果不其然,阿美卡表现出了愤怒……
据该公司介绍,开发者利用了美国Open AI公司的人工智能聊天机器人GPT-3来生成回应,并将它们与合适的面部表情关联起来。
团队表示,他们也尝试使用最新版本的 GPT-4 来进一步改进结果。然而,GPT-4更长的处理时间导致机器人反应较慢,使对话显得不那么自然。
“在这个视频中,合适的面部表情是由GPT-3选择的。我们也尝试了GPT-4,但由于GPT-4的处理时间较长,使阿美卡的表现没那么好。”公司在视频配文中介绍。
The developers of Ameca utilized OpenAI's GPT-3 artificial intelligence not only for generating responses but also for associating them with suitable facial expressions.
The team attempted to use the latest version, GPT-4, to enhance the results even further. However, the increased processing time resulted in the robot being less responsive and made the conversation feel less spontaneous.
早在去年 11 月,该公司就已经通过使用一个合成器,让阿美卡朗读 GPT-3 提供的回应,以展现“说话”的效果。相比之下,当时的面部表情还比较基础。
As early as the previous November, the company had enabled Ameca to speak using a synthesizer that dictated responses provided by GPT-3, though the facial expressions at that stage were still rudimentary.
如今,搭载GPT-3生成合适的面部表情,让阿美卡看起来不仅外形逼真,似乎还拥有了与真人无二的情绪。不少外国网友在评论区感叹“令人震惊”,也有人认为有点吓人。↓
“厉害!”
“这令人难以置信。有趣的是,在使用CGI技术时,嘴唇的运动是很难准确的。”
“好像《西部世界》。”
“这有点恐怖,我不确定我喜不喜欢。”
有网友截取了视频中阿美卡愤怒的表情说,“不了,谢谢。”
以后,随着人工智能的进步,阿美卡还能发展到什么地步,让我们拭目以待吧!
