Question
You are developing a web app that processes invoices to calculate expenses.
You need to extract structured fields, including nested values, from the invoices by using a defined schema.
What should you use?
- A. an optical character recognition (OCR)-only document processing pipeline
- B. a transcription workflow in Azure Speech in Foundry Tools
- C. an analyzer in Azure Content Understanding in Foundry Tools Correct
- D. an Azure AI Search service
Explanation
An analyzer in Azure Content Understanding lets you define a schema and extract structured fields, including nested and hierarchical values, from documents such as invoices. An OCR-only pipeline merely returns raw text with no schema-based structured extraction, Azure Speech handles audio transcription rather than documents, and Azure AI Search provides indexing and retrieval rather than schema-driven field extraction.
