AWS Certified Machine Learning – Specialty — Question 91

A large company has developed a BI application that generates reports and dashboards using data collected from various operational metrics. The company wants to provide executives with an enhanced experience so they can use natural language to get data from the reports. The company wants the executives to be able ask questions using written and spoken interfaces.
Which combination of services can be used to build this conversational interface? (Choose three.)

Answer options

Correct answer: C, D, F

Explanation

The correct services for building a conversational interface are Amazon Lex, which enables natural language understanding, Amazon Polly, which converts text to lifelike speech, and Amazon Transcribe, which transcribes spoken language into text. Alexa for Business and Amazon Connect are more focused on voice assistant capabilities and customer service interactions, while Amazon Comprehend is used for natural language processing but does not directly contribute to the conversational interface in this scenario.
