Microsoft Cognitive Service (earlier called as  Project Oxford) is a bunch of APIs, SDKs and services available to software developers to build  intelligent, smart and discoverable applications .

Microsoft Cognitive Services focuses on Microsoft’s growing portfolio of machine learning APIs and it easily enables developers to add intelligent features – like detecting emotion in images; facial recognition, speech translation and vision recognition; and speech and language understanding – into their applications.

Microsoft’s vision is provide more and more personal computing experiences and enhanced productivity to each person and organisation on this planet by intelligent systems that increasingly can see, hear, speak, understand and even begin to reason.
