什么是 Azure 认知服务?What are Azure Cognitive Services?

Azure 认知服务是具有 REST API 和客户端库 SDK 的基于云的服务,可用于帮助你将认知智能构建到应用程序中。Azure Cognitive Services are cloud-based services with REST APIs and client library SDKs available to help you build cognitive intelligence into your applications. 即使你没有人工智能 (AI) 或数据科学技能,也可向应用程序添加认知功能。You can add cognitive features to your applications without having artificial intelligence (AI) or data science skills. Azure 认知服务包含各种 AI 服务,让你能够构建可以看、听、说、理解,甚至可以决策的认知解决方案。Azure Cognitive Services comprise various AI services that enable you to build cognitive solutions that can see, hear, speak, understand, and even make decisions.
