A call center is integrating an AI-powered assistant to help agents by transcribing customer calls in real-time. The company has a strict compliance requirement to automatically detect and redact any Personal Identifiable Information (PII) from the transcripts before they are stored or displayed to agents. Which Azure AI Language feature should be used for this purpose?
- AKey Phrase Extraction
- BPII Detection
- CNamed Entity Recognition (NER)
- DSentiment Analysis
Show answer & explanationAnswer & explanation
Correct answer: B. PII Detection
PII Detection is specifically designed to identify and redact sensitive information like names, addresses, phone numbers, and financial data from unstructured text, directly addressing the compliance requirement for redacting PII from call transcripts.
Why the other options are wrong
- A. Key Phrase Extraction identifies main topics, not sensitive personal data.
- C. While NER can identify some entities (like names), PII Detection is a specialized and more comprehensive feature for various types of sensitive personal information and often includes redaction capabilities.
- D. Sentiment Analysis identifies emotional tone, not PII.
