Amazon Comprehend
Amazon Comprehend is a natural language processing (NLP) service that extracts sentiment, key phrases, and named entities from text.
Its input is text, and the step of converting recorded audio into text is the role of Transcribe, so it is incorrect. The correct combination is to use it for analysis after transcription.
CIncorrect
Amazon Translate
Amazon Translate is a service that translates text into another language.
It is not a service that transcribes audio into text, so it is incorrect.
DCorrect
Amazon Transcribe
Correct. Amazon Transcribe is an AI service that converts speech into text (speech recognition / transcription). It automatically turns meeting and call center recordings into text for use in search, analysis, and subtitle generation.
Key Takeaway
Transcribe = speech to text (transcription) / Polly = text to speech (synthesis). Translation is Translate, and text analysis is Comprehend. Identify the AI service by its input and output.
