Amazon Polly는 인공 지능 기반 음성 합성 클라우드 서비스로서 한국어를 포함 수십개의 언어 및 음성을 지원하여, 텍스트에서 음성을 만들어 고객 센터, 교육 및 음성 가이드 등 다양한 기능에 활용할 수 있습니다. 본 세션에서는 Amazon Polly에 대한 소개와 다양한 기능을 알아보고, 특히 SSML (음성 의미 표준)을 통해 원하는 음성 변환 방식으로 만들어 낼 수 간단한 동화 구연 앱을 AWS Lambda 기반 서버리스 앱으로 만들어 봅니다. AWS가 새로 출시하는 클라우드 기반 가상 현실 저작 도구인 Amazon Sumerian을 통해 이를 VR/AR 콘텐츠로 제작하는 샘플 사례를 소개합니다.
