用统一音素标签集实现印地次大陆多语言语音无缝切换
Everyday Speech in the Indian Subcontinent
- 基于音素构建统一标签集，解决多语言合成词汇量大问题
- 支持13种印度语言与英语在母语者音色中自然切换
- 适用于真实多语言环境中日常口语的语音合成
印度有1369种语言，其中22种为官方语言，约使用13种不同文字。为解决端到端语音合成中所需大量词汇单元的问题，研究提出基于音素的通用标签集（CLS）。将印度语言文本先转换为该标签集，使系统可在同一母语者音色下无缝切换13种印度语言及英语，模拟印地次大陆居民日常多语言交流的真实场景。
原文摘要 · Abstract (English)
India has 1369 languages of which 22 are official. About 13 different scripts are used to represent these languages. A Common Label Set (CLS) was developed based on phonetics to address the issue of large vocabulary of units required in the End-to-End (E2E) framework for multilingual synthesis. The Indian language text is first converted to CLS. This approach enables seamless code switching across 13 Indian languages and English in a given native speaker's voice, which corresponds to everyday speech in the Indian subcontinent, where the population is multilingual.
