AWS Certified AI PractitionerAWS Services for AI/ML and Generative AIEasy
A financial institution is developing an application that needs to generate highly realistic, human-like speech from written text for its virtual assistant. The institution requires a service that supports multiple languages and lifelike voices, including custom brand voices. Which AWS service should they use?
- AAmazon Transcribe
- BAmazon Polly
- CAmazon Lex
- DAmazon Comprehend Medical
Show answer & explanationAnswer & explanation
Correct answer: B. Amazon Polly
Amazon Polly is a text-to-speech (TTS) service that turns text into lifelike speech, allowing you to create applications that talk. It supports dozens of languages and offers a Neural Text-to-Speech (NTTS) option for even more natural-sounding voices, as well as Brand Voice creation.
Why the other options are wrong
- A. Amazon Transcribe converts speech to text, the opposite of the requirement.
- C. Amazon Lex is used for building conversational interfaces (chatbots), not for generating speech from text.
- D. Amazon Comprehend Medical is for extracting health information from medical text, unrelated to speech generation.
