What capabilities does Azure Cognitive Services provide for NLP?

Azure Cognitive Services offers a wide range of APIs designed specifically for various natural language processing functionalities. This includes capabilities such as sentiment analysis, language detection, entity recognition, text analytics, and language understanding (LUIS). By providing these APIs, Azure enables developers to integrate advanced NLP features into their applications without needing to build the underlying machine learning models from scratch.

The choice that indicates APIs for machine learning only lacks the comprehensive scope of NLP functionalities, as Azure Cognitive Services encompasses much more than just traditional machine learning capabilities. Options suggesting tools for data visualization or models specifically for speech synthesis do not capture the breadth of NLP capabilities provided within Azure Cognitive Services, as they focus on other areas of data handling and speech rather than text processing and understanding. Thus, the option that emphasizes APIs for various NLP functionalities accurately represents the extensive range of services offered by Azure Cognitive Services in the domain of natural language processing.
