AWS Certified Solutions Architect Professional Practice (SAP-C02) Practice Exam

The concept being tested is turning text into spoken audio within a contact flow. Amazon Polly is the service that does this by converting text into natural-sounding speech that can be played in customer contact experiences, such as Amazon Connect prompts and responses. Polly supports multiple languages and voices, and can handle SSML for nuanced speech, making it ideal for dynamic, spoken interactions in contact flows.

The other options don’t provide text-to-speech capabilities: the AWS CLI is just a command-line tool for managing AWS resources, Amazon Rekognition analyzes images and videos, and Amazon SageMaker is for building and hosting machine learning models.
