Free Microsoft Azure AI-102 Actual Exam Questions - Question 3 Discussion
HOTSPOT You are building an app that will answer customer calls about the status of an order. The app will query a database for the order details and provide the customers with a spoken response. You need to identify which Azure Al service APIs to use. The solution must minimize development effort. Which object should you use for each requirement? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. 
I’d go with Speech to Text for converting the customer’s spoken query into text, since that’s the natural first step before checking order status. Then, once you pull up the order info, use Text to Speech to give the response back as audio. The Language Understanding service seems unnecessary here because you’re not really interpreting complex intents, just matching a direct query to data. So B for converting speech input and D for generating the spoken output makes the most sense to me. It keeps things straightforward without extra processing steps.
B for speech-to-text to get live transcription, and LUIS for understanding intent.
If the calls are live, using the Speech SDK for real-time transcription (option B) makes sense and reduces development effort. Batch transcription (A) would add delay, so probably not ideal here.
Definitely not Text Analytics-that’s for analyzing text, not speech or calls.
