In this article, we will discuss Microsoft Azure Cognitive Services in the Azure portal.


Microsoft Cognitive Services (formerly Project Oxford) is a collection of APIs that enables natural and contextual interaction with tools that augment users' experiences via the power of machine learning models from Microsoft. Microsoft Cognitive Services expands on Microsoft’s evolving portfolio of machine learning APIs and enables developers to easily add intelligent features - such as emotion and video detection; facial, speech and vision recognition, speech and language understanding - into their Applications.

Cognitive Services helps you to build apps with powerful algorithms, using just a few lines of code. These services work across the devices and platforms such as iOS, Android and Windows, keep improving and are easy to set up.

Currently, Azure supports Cognitive Services preview in the Azure portal.
