AIF-C01 Practice Question: Convert a large number of recorded customer…
A company needs to convert a large number of recorded customer service calls into text for analysis. Which AWS service should they use?
⚠ Common exam trap
Watch out — candidates often confuse Amazon Transcribe (speech-to-text) with Amazon Polly (text-to-speech) or Amazon Textract (text from images), as candidates often misremember which AWS service handles audio transcription versus document text extraction.
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 Transcribe
Amazon Transcribe is the correct service because it is specifically designed to convert speech from audio files (such as recorded customer service calls) into text using automatic speech recognition (ASR). This directly matches the requirement to transcribe audio content for subsequent text analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon Textract
Why it's wrong here
Textract extracts text and data from scanned documents and images using OCR; it cannot process audio recordings. It is tempting because it converts unstructured input into analysable text, making it the right choice when the source material is PDFs, forms or scanned images rather than call recordings.
- ✗
Amazon Comprehend
Why it's wrong here
Comprehend performs natural language processing such as sentiment, entity and key-phrase extraction on existing text; it does not transcribe audio. It is tempting because it analyses call content, making it the right choice once speech has already been converted to text and the goal is deriving insights from that transcript.
- ✓
Amazon Transcribe
Why this is correct
Amazon Transcribe is the managed automatic speech recognition service that converts audio recordings into text transcripts. It handles batch call recordings directly, satisfying the requirement to transform a large volume of customer service calls into analysable text.
- ✗
Amazon Polly
Why it's wrong here
Polly performs text-to-speech synthesis, converting written text into spoken audio — the reverse of the required direction. It is tempting because it handles voice, making it the right choice when generating spoken output such as accessibility narration or interactive voice responses from existing text.
