The ability to understand the meaning and intent behind spoken words, not just transcribe them (Correct answer)
Voice biometric authentication
Faster audio transcription
Multi-language translation in real time

Correct answer: The ability to understand the meaning and intent behind spoken words, not just transcribe them

NLU interprets the semantic intent of a caller's utterance, allowing the IVR to understand requests like 'I want to change my address' rather than matching keywords.
