Community Votes
100% of anonymous learners picked answer B. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The question tests knowledge of AI/ML services by asking for a text-to-speech solution, with the common trap being confusion between message brokers, databases, and speech synthesis tools.
Amazon Polly is the AWS service designed to convert text into lifelike speech, making it the correct choice for accessibility applications. This page explains why other compute and storage services are unsuitable for this specific task.
Learners might incorrectly choose Amazon MQ, confusing it as a general-purpose service, or Neptune/Timestream due to unfamiliarity with their specialized database roles.

Expert Analysis
Why the Answer Is Correct
Amazon Polly is a cloud-based text-to-speech service that uses deep learning to deliver natural-sounding synthetic speech. It supports multiple languages and SSML (Speech Synthesis Markup Language), allowing developers to build applications that interact with users via voice, which directly satisfies the requirement for an accessibility application converting text to audible speech.Why the Other Options Are Wrong
Amazon MQ is a managed message broker service for interoperable messaging between microservices, not audio processing. Amazon Neptune is a fully managed graph database service optimized for storing and querying highly connected datasets. Amazon Timestream is a fast, scalable, serverless time-series database service for IoT and analytics applications. None of these services provide speech synthesis capabilities.Community Comment Notes
The community consensus is unanimous, with all visible comments confirming B as the correct answer. Users like ShaiTay explicitly note that Amazon Polly converts text to life-like speech, reinforcing the direct mapping between the service name and the functional requirement.Exam Strategy
When identifying AWS services, focus on the core function described in the scenario. For 'text-to-speech' or 'speech recognition', immediately think of Amazon Polly or Amazon Transcribe. Avoid getting distracted by infrastructure services like databases or message queues.
