AIF-C01 Practice Question: Build a system that converts text-based customer…
A company needs to build a system that converts text-based customer reviews into audio files for accessibility. Which AWS service should be used?
⚠ Common exam trap
Many candidates confuse Amazon Transcribe (speech-to-text) with Amazon Polly (text-to-speech), or mistakenly think Amazon Comprehend can generate audio because it processes text, but neither service produces audio output.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Polly
Amazon Polly is a text-to-speech (TTS) service that converts text into lifelike speech, making it the correct choice for generating audio files from text-based customer reviews. It supports multiple languages and voices, and can output audio in formats like MP3 or OGG, which is ideal for accessibility use cases. The other listed services do not convert text to audio: Amazon Transcribe converts speech to text, Amazon Translate translates text, Amazon Rekognition analyzes images and video, and Amazon Comprehend performs natural language processing. Therefore, only one correct answer exists among the options.
