Suggested Answer:


Explanation:
Box: Natural Language Understanding (NLU)
A virtual assistant that converts spoken requests into written text relies primarily on Automatic Speech Recognition (ASR) or Speech-to-Text first, while Natural Language Understanding (NLU) is used subsequently to extract meaning, intent, and entities from that generated text.
How the Workload Splits
Speech-to-Text (ASR):
Turns audio waves into raw text words.
Handles accents, background noise, and phonetic matching.
Natural Language Understanding (NLU):
Analyzes the text produced by the ASR engine.
Figures out what the user actually wants (intent).
Finds key details like dates, names, or items (entities).
