Initially, Microsoft Cognitive Services was known as Microsoft Project Oxford. It is also known as suite of intelligent APIs and works across platforms which provide facial recognition in images, voice recognition of speakers, language processing, Academic Knowledge, and more.

You must try out all the APIs that are available and just play around. For example, APIs such as Face, Emotion, and Speaker recognition will always return a confidence rating/value for each emotion identified in a given image from Face & Emotion APIs. In the case of Speaker recognition, it will tell you how much it accurately matches the voice to your previously registered voice. The best machine learning example API is Language Understanding Intelligent Service (LUIS)....
