构建首个布姆巴语到英语的语音翻译系统,解决非洲低资源语言难题
Bemba Speech Translation: Exploring a Low-Resource African Language
- 基于Whisper与NLLB-200搭建级联语音翻译系统
- 通过回译等数据增强提升低资源语言性能
- 为非洲语言语音翻译提供可复现的技术方案
本文介绍我们针对国际口语翻译会议(IWSLT 2025)低资源语言赛道提交的布姆巴语到英语语音翻译系统。系统基于Whisper和NLLB-200构建级联式语音翻译架构,并采用回译等数据增强技术。研究探讨了合成数据对模型表现的影响,详细说明了实验设置,为低资源非洲语言的语音翻译提供了可行方案。
原文摘要 · Abstract (English)
This paper describes our system submission to the International Conference on Spoken Language Translation (IWSLT 2025), low-resource languages track, namely for Bemba-to-English speech translation. We built cascaded speech translation systems based on Whisper and NLLB-200, and employed data augmentation techniques, such as back-translation. We investigate the effect of using synthetic data and discuss our experimental setup.
