AI-102 Question 224
Single answerYou are designing an Azure AI solution that should detect specific spoken keywords from a live audio stream in real time. The solution must use a pre-trained service and minimize custom model training efforts. Which Azure service or component should you use to implement this functionality?
- A
Azure Speech SDK with Keyword Recognition
- B
Azure Form Recognizer
- C
Azure Cognitive Search
- D
Azure Bot Framework with QnA Maker
Show answer and explanation
Correct answer: A
Explanation
Keyword recognition in audio streams is a feature provided by the Azure Speech SDK. It allows developers to specify a set of custom words or phrases to detect without requiring additional training. Other options like Form Recognizer, Cognitive Search, and Bot Framework are not designed for audio processing tasks like keyword spotting.
- A. Correct.
Azure Speech SDK with Keyword Recognition is specifically designed for real-time keyword spotting in audio streams. It provides pre-trained capability to detect specific keywords, fulfilling the requirements.
- B. Incorrect.
Azure Form Recognizer is used for extracting information from documents like invoices or receipts. It is not suitable for audio processing or keyword recognition.
- C. Incorrect.
Azure Cognitive Search is designed for indexing and searching across large text data and does not support audio or keyword detection.
- D. Incorrect.
Azure Bot Framework with QnA Maker is used for building conversational bots and knowledge bases, not for audio keyword recognition.
