Hotspot Solution:
Cognitive. Closed captioning is speech‑to‑text, which is an Azure Cognitive Service. Cognitive analytics is about enabling systems to perceive unstructured data — audio, images, natural language, etc. Descriptive analytics, on the other hand, works on structured, historical, already‑summarized data to answer “what happened?” (dashboards, reports, KPIs). Closed captioning does not summarize or analyze past business data — it simply interprets raw audio. Because the task involves AI perception rather than summarizing structured data, the correct category is Cognitive, not Descriptive.

COGNITIVE: Closed Captions (CC) refer to the textual transcription of spoken content derived from audio or video files. The system must use Artificial Intelligence (AI) and Machine Learning (ML) to simulate the human ability to hear, interpret, and process natural language (speech recognition) to convert sound into text. Cognitive analytics uses machine learning algorithms (specifically Natural Language Processing and Speech-to-Text in this case) to derive insights and convert unstructured data (audio) into structured outputs (text).
The answer is "Descriptive Analytics" and not cognitive. Because it focuses on summarizing or describing what was said in the audio. It doesnt involve prediction, inference or reasoning to be called as cognitive. Descriptive - is the right answer.
