Short Explanation
Think of a cook with wet hands who needs the allergen card shouted over the pass. Amazon Polly turns written text into speech. Transcribe goes the other way, Translate changes language, and Lex would start a booking chat nobody asked for.
Full Explanation
Commercial-kitchen allergen cards that are already written and must be read aloud over the pass are text-to-speech, which Amazon Polly provides. Polly matches because cooks need audio from existing written cards while their hands are wet and cannot safely hold a tablet, and the kitchen is not asking to turn spoken tickets into text. Amazon Transcribe would convert speech audio into text—the opposite transform—and the stem rejects that need for this pass workflow. Amazon Translate would change the language of the cards rather than speak the existing wording cooks already trust. Amazon Lex would open an interactive reservation-style dialog with slots and confirmations, which is unnecessary when the only requirement is reading known card text aloud on demand. Direction of the transform is the whole game: written allergen facts go out as audio, not the reverse. Exam caveat: Polly is text→audio; Transcribe is audio→text—exam items frequently invert those arrows with kitchen or call-center stories. Operational check: send a sample allergen card string to Polly, play it at pass volume in a noisy kitchen test, and confirm cooks can hear critical allergen words without launching a Lex bot or a translation step.
