在 Power Platform 通过 AI Builder 和 Power Virtual Agents 提供人工智能功能之前，微软推出了 Azure 认知服务。Azure 认知服务为开发人员提供了一种简单的方法，让他们无需了解创建智能服务背后的复杂性，即可将人工智能引入其解决方案。这些服务分为几个类别：语音、语言、视觉、决策和 OpenAPI。
例如，语音服务允许您 执行将语音转录为文本、将文本转换为语音以及语音翻译等任务。语言服务可以识别文本中的术语，或提供情感评分，帮助你判断语句是正面还是负面等。视觉服务包括计算机视觉（Computer Vision）和人脸 API，前者可以让你分析图像和视频，后者可以检测图像中的人物，识别他们脸上的情绪等。这些服务在不断变化和发展，虽然许多可用的功能都在 AI Builder 等工具中，但有些时候你可能想用 Azure 认知服务来代替。例如，如果您没有 AI Builder 许可证，但您的组织已经设置了一个或多个认知服务，您仍然可以在 Power Automate 中利用这些解决方案。

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
