Use AI to solve business problems


Image-processing algorithms to smartly identify, caption, index, and moderate your pictures and videos.


Convert spoken audio into text, use voice for verification, or add speaker recognition to your app.


Map complex information and data in order to solve tasks such as intelligent recommendations and semantic search.


Add Bing Search APIs to your apps and harness the ability to comb billions of webpages, images, videos, and news with a single API call.


Allow your apps to process natural language with pre-built scripts, evaluate sentiment and learn how to recognize what users want.

Anomaly Detection

Add anomaly detection capabilities to your apps to identify problems as soon as they occur.

“Because the Cognitive Services APIs harness the power of machine learning, we were able to bring advanced intelligence into our product without the need to have a team of data scientists on hand.”

Enhance security with a face

Use the Face API to verify a selfie for smart authentication. Signing in with visual identity verification is becoming an additional security layer for many industries. Microsoft's Face API can compare portraits giving it amazing flexibility in uncontrolled scenarios.

Express dramatic moments in an instant

Quickly retrieve surprised, happy, or sad celebrity images out of millions by combining multiple APIs. Search through video frames to pull out the perfect moment for your content. Never let an abundance of untagged footage be a deterrent for your ability to serve up contextual content when you need it.

Engage your customers through chat

Bring together Cognitive Service APIs and Bot Framework to engage your audience on a whole new level. Build a bot that embodies your brand, addresses your customers’ main questions and escalates to a human operator if needed.

Enable great voice interactions with speech customization

With the Custom Speech Service you can build great voice interactions between your systems and your users. Enhance speech recognition using background noise reduction and complex technical word training.

Computer Vision

This feature returns information about visual content found in an image. Use tagging, descriptions, and domain-specific models to identify content and label it with confidence.

Language Understanding (LUIS)

Our Language Understanding service (LUIS) provides simple tools that enable you to build your own language models, which allow any application or bot to understand your commands and act accordingly.

Speaker Recognition

Identify who is speaking. Input audio of the unknown speaker is paired against a group of selected speakers, and in the case there is a match found, the speaker’s identity is returned.
