Exam AWS Certified Machine Learning - Specialty topic 1 question 97 discussion

The question states that the company wants to "provide executives with an enhanced experience so they can use natural language to get data from the reports." The key phrase here is "use natural language," which implies that the executives will be interacting with the system using human-like language, either written or spoken. To understand and interpret natural language inputs from users, whether written or spoken, the system needs to have natural language understanding (NLU) or natural language processing (NLP) capabilities. Without NLU/NLP capabilities, the system would not be able to make sense of the executives' natural language queries and extract the relevant information to retrieve data from the reports and dashboards. Services like Amazon Lex and Amazon Comprehend are specifically designed to provide NLU and NLP functionalities, respectively. Amazon Lex uses NLU models to understand the intent and extract relevant information from user inputs, while Amazon Comprehend provides NLP capabilities to analyze and extract insights from text data.

I second that, the keyword here is "conversational interface". so, no conversation without Amazon Lex
