Yes

According to the Microsoft Azure AI Fundamentals (AI-900) official study materials and Microsoft Learn modules on AI workloads, each of these statements maps to a distinct area of artificial intelligence — namely Conversational AI, Speech AI, and Natural Language Processing (NLP).

“A webchat bot can interact with users visiting a website.” – YesThis is true. A webchat bot represents an example of Conversational AI. It leverages natural language understanding (NLU) to interpret user input and generate appropriate responses. These bots can be created using Azure services such as Azure AI Bot Service and Language Understanding (LUIS). They enable automated interactions with users through text-based communication on websites, applications, or messaging platforms.

“Automatically generating captions for pre-recorded videos is an example of natural language processing.” – NoThis is false. Generating captions from audio involves speech recognition, not NLP. Specifically, it uses speech-to-text technology to transcribe spoken words into written text. This function is typically performed by Azure’s Speech service, which is part of the Speech AI workload, not the language-processing workload.

“A smart device in the home that responds to questions such as ‘What will the weather be like today?’ is an example of natural language processing.” – YesThis is true. Smart assistants like Alexa or Cortana use NLP to interpret spoken queries, extract meaning, and generate appropriate responses. NLP allows these devices to understand human language, retrieve relevant information, and respond conversationally.
