Azure AI Services
Azure AI Services are cloud-based artificial intelligence services that help developers build cognitive intelligence into applications without having direct AI or data science skills. These services provide pre-trained models and APIs across multiple AI domains.Available AI Services
Azure AI Services span four main categories: Vision, Language, Speech, and Decision APIs.Computer Vision
Analyze images and videos to extract visual features, detect objects, read text, and generate captions
Document Intelligence
Extract text, tables, and structure from documents with OCR and intelligent document processing
Custom Vision
Build custom image classification and object detection models for your specific use cases
Language
Natural language processing for text analysis, entity recognition, sentiment analysis, and more
Translator
Neural machine translation across 100+ languages with real-time text and document translation
Speech
Speech-to-text, text-to-speech, speech translation, and voice recognition capabilities
Anomaly Detector
Detect anomalies in time series data with univariate and multivariate detection (retiring)
Personalizer
Reinforcement learning service for personalized content recommendations (retired)
Content Understanding
Process and analyze documents, images, videos, and audio with generative AI
