Multilingual PII Detection with Azure AI Language
You are designing a solution to detect personally identifiable information (PII) in documents using Azure AI Language. The solution must also handle documents in multiple languages. Which THREE features should you use?
Quick Answer
The answer is to use the multilingual support in Azure AI Language PII detection, the language detection API, and the multilingual model for mixed-language documents. These three features work together because Azure AI Language’s PII detection natively supports over 20 languages, while the language detection API identifies the primary language of each document to ensure the correct model is applied, and the multilingual model can process documents containing multiple languages in a single text block without requiring separate preprocessing. On the AI-102 exam, this scenario tests your understanding of how to combine Azure AI Language’s built-in multilingual capabilities rather than relying on separate translation services—a common trap is choosing Text Analytics for health or conversation summarization, which are domain-specific and not designed for general PII detection. Remember the mnemonic: “Detect, Detect, Detect” — detect the language, detect PII, and detect mixed-language content with the same multilingual model.
⚠ Common exam trap
Many exam-takers assume PII detection alone handles all languages automatically, overlooking the explicit need to first detect the language and then pass it as a parameter to the PII detection API for accurate multilingual support.

Correct answer & explanation
✓
The language detection feature of Azure AI Language.
Azure AI Language's language detection feature is necessary to identify the language of each document before applying PII detection, ensuring the correct language-specific model is used for accurate entity extraction. This is a prerequisite step in a multi-language PII detection pipeline, as the PII detection API requires the language parameter to be set appropriately.

Variation 1. A healthcare organization needs to redact personally identifiable information (PII) from patient records before using them for research. They have large volumes of unstructured text in multiple languages. Which Azure AI service should they use?
easy- A.Azure AI Content Safety
- ✓ B.Azure AI Language (PII detection feature)
- C.Azure AI Document Intelligence (formerly Form Recognizer)
- D.Azure AI Translator
Why B: Azure AI Language's PII detection feature is specifically designed to identify and redact personally identifiable information from unstructured text. It supports multiple languages and can handle large volumes of text, making it the correct choice for redacting PII from patient records before research use.
