Use AI to solve business problems


Build apps that surface recommendations for informed and efficient decision-making.


Recognize, identify, caption, index, and moderate your pictures, videos, and digital ink content.


Convert speech into text and text into natural-sounding speech. Translate from one language to another and enable speaker verification and recognition.


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.

"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."

Kick off your artificial intelligence (AI) development with this comprehensive guide to integrating and combining intelligent APIs available through Azure Cognitive Services. Whether through computer vision, speech recognition and language processing, or knowledge and search, you’ll gain a deeper understanding of what’s possible. You’ll learn about identifying through visual inspection and audio, reducing user effort by building AI-like capabilities, analyzing images and text in different ways, and using search APIs to find the information you need.

Cutting-edge tech companies use Microsoft APIs every day

Neural Text to Speech

Applying the latest in deep learning innovation, the Neural Text to Speech capability makes the voices of your apps nearly indistinguishable from recordings of people. The natural inflection and clear articulation significantly reduce listening fatigue when interacting with AI systems.

Conversation Transcription

Get the most out of every minute. Combine Conversation Transcription with the Speech Services Device SDK to support meeting scenarios so participants can equally engage in the discussion, know who said what when, and quickly follow up on next steps.

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.
