Cognitive Services

Put intelligence APIs to work

Microsoft Cognitive Services let you build apps with powerful algorithms to see, hear, speak, understand and interpret our needs using natural methods of communication, with just a few lines of code. Easily add intelligent features – such as emotion and sentiment detection, vision and speech recognition, language understanding, knowledge and search – into your app, across devices and platforms such as iOS, Android, and Windows, keep improving, and are easy to set up.
