AI-102 Plan and manage an Azure AI solution Practice Question

Your team is developing a chatbot using Azure AI Bot Service with Language Understanding (LUIS). You need to improve intent recognition for user queries that contain typos. What should you recommend?

⚠ Common exam trap

Test-takers frequently assume training with typos (Option D) is the best way to handle misspellings, but Microsoft explicitly recommends using Bing Spell Check as a separate preprocessing layer rather than bloating the training data with error-prone examples.

Correct answer & explanation

✓

Enable Bing Spell Check in the LUIS app settings

Enabling Bing Spell Check in the LUIS app settings allows the service to automatically correct typos in user utterances before they are processed for intent recognition. This built-in feature integrates directly with LUIS at the endpoint, correcting misspelled words to improve the accuracy of intent and entity extraction without requiring manual data augmentation or external services.
