Which AWS service enables real-time translation of text between languages for applications serving a global audience?

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 Comprehend
Why it's wrong here
Amazon Comprehend is a natural language processing (NLP) service that analyzes text to extract insights such as sentiment, entities, key phrases, and language metadata. It operates on the input text in its original language and returns analytical labels or classifications, but it does not generate translated text. Since the question asks for translation between languages, Comprehend is incorrect because it provides understanding and structure, not cross-language rendering.
- ✗
Amazon Polly
Why it's wrong here
Amazon Polly is a text-to-speech (TTS) service that converts written text into lifelike speech using a variety of voices and languages, but it does not translate the text itself. It simply reads aloud whatever text is provided, in the same language as that text, with no capability to change the source language to a different target language. Therefore, it is not suitable for translation tasks; its function is speech generation, not language conversion.
- ✓
Amazon Translate
Why this is correct
Amazon Translate is a neural machine translation service that uses deep learning models to automatically convert text from a source language to a target language while preserving meaning and context. It offers both real-time and batch translation across dozens of language pairs through a simple API, making it the correct choice for cross-language content localization. Unlike speech or analysis services, its core purpose is to output text in a different language than the input.
- ✗
Amazon Transcribe
Why it's wrong here
Amazon Transcribe is an automatic speech recognition (ASR) service that converts audio or video speech into text format. It produces time-stamped transcripts in the same language as the original audio, often with custom vocabulary or speaker diarization, but it never translates the recognized text into another language. Therefore, it fails the requirement for cross-language translation because its output remains in the original spoken language, not a translated target language.
