Question #1317

A company wants to implement a text-to-speech feature for their e-learning platform. Which AWS service should they use?

A

Amazon Transcribe

B

Amazon Polly

C

Amazon Comprehend

D

AWS Glue

Explanation

Amazon Polly (B) is the correct answer because it is a text-to-speech service that uses advanced deep learning technologies to synthesize natural-sounding human speech. This directly addresses the requirement of converting text into speech for the e-learning platform.

- Why other options are incorrect:
- A. Amazon Transcribe: This is a speech-to-text service, which performs the opposite function (converting audio to text).
- C. Amazon Comprehend: This is a natural language processing (NLP) service for analyzing text (e.g., sentiment analysis, entity recognition), not generating speech.
- D. AWS Glue: This is an ETL (Extract, Transform, Load) service for data integration and preparation, unrelated to text-to-speech.

Key Points:
- Use Amazon Polly for text-to-speech applications.
- Use Amazon Transcribe for speech-to-text conversions.
- Use Amazon Comprehend for NLP tasks like sentiment analysis.
- Use AWS Glue for data integration workflows.

Answer

The correct answer is: B
