Cortana Analytics Perceptual APIs
With the Perceptual APIs inside Cortana Analytics Suite, you can quickly develop applications that require insights from opaque multimedia streams such as text, audio, and image. These general-purpose machine learnt models have been used across many Microsoft first-party products and are now available as part of Azure to power your applications. Computer Vision & Face APIs let your code understand and manipulate image content (these APIs helped power www.how-old.net, the age prediction website). Speech APIs enable you to communicate with users using audio, thanks to both speech recognition as well as speech synthesis. Text Analytics determines a range of attitude from text using sentiment analysis; in addition, your apps will be able to identify key phrases behind sentiment. LUIS brings natural-language understanding to any application through a simple model creation UX that relies on active learning to improve the model with use over time.
