Abstract
We propose an integrated text summarization and text-to-speech framework which summarizes Korean documents into a few sentences and reads them in a specific person’s voice. In our framework, a pre-trained text summarization model (KoBART) is fine-tuned with an additional news-oriented text summarization dataset. Then, the fine-tuned model is compressed by knowledge distillation (DistilKoBART) to improve computational efficiency. For text-to-speech, Tacotron 2 and Waveglow models are used. To generate a natural speech sample, we design a task-specific transliteration module that converts numeric or English expressions into Korean. The experimental results show that the proposed framework effectively summarizes long documents and provides a human-like synthesized voice. The proposed framework can provide convenience such as fast information delivery to busy modern people or effectively deliver information to users in special situations such as drivers and people with low vision. 이 논문은 2021년도 정부(과학기술정보통신부)의 재원으로 정보통신기획평가원의 지원을 받아 수행된 연구임(No.2021-0-00034, 파편화된 데이터의 적극 활용을 위한 시계열 기반 통합 플랫폼 기술 개발). 또한 이 연구는 한국산업기술진흥원의 산업인공지능인력양성사업의 지원을 받아 수행되었음(P0008691). †연락저자:강필성 교수, 02841, 서울시 성북구 안암로 145 고려대학교 산업경영공학부, Tel: 02-3290-3383, Fax: 02-929-5888, E-mail: pilsung_kang@korea.ac.kr2021년 9월 14일 접수; 2021년 10월 18일 수정본 접수; 2021년 11월 30일 게재 확정.
