AI总结:

本研究提出一种从有声读物生成ASR训练数据集的新颖流水线,通过有效对齐和分割音频文本,解决了低资源语言数据稀缺问题并提升了模型性能。

摘要:

近年来,自动语音识别(ASR)系统显著改善,尤其是在拥有大量转录语音数据的语言中。然而,对于资源较少的低资源语言,如少数民族语言和区域语言,ASR系统往往表现不佳。本研究引入了一种新颖的流水线,旨在从有声读物中生成ASR训练数据集,这些有声读物通常具有与数小时音频相对应的单个转录文本。这些有声读物的常见结构带来了独特挑战,因为音频片段长度过长,而最佳的ASR训练需要4到10秒长度的片段。为解决这一问题,我们提出了一种有效对齐音频及其对应文本并将其分割为适合ASR训练长度的方法。我们的方法简化了低资源语言ASR系统的数据准备工作,并通过涉及亚美尼亚语言的案例研究展示了其应用。我们的方法可“移植”到许多低资源语言,不仅缓解了数据稀缺问题,还提升了代表性不足语言的ASR模型性能。

英文摘要:

In recent years, automatic speech recognition (ASR) systems have significantly improved, especially in languages with a vast amount of transcribed speech data. However, ASR systems tend to perform poorly for low-resource languages with fewer resources, such as minority and regional languages. This study introduces a novel pipeline designed to generate ASR training datasets from audiobooks, which typically feature a single transcript associated with hours-long audios. The common structure of these audiobooks poses a unique challenge due to the extensive length of audio segments, whereas optimal ASR training requires segments ranging from 4 to 15 seconds. To address this, we propose a method for effectively aligning audio with its corresponding text and segmenting it into lengths suitable for ASR training. Our approach simplifies data preparation for ASR systems in low-resource languages and demonstrates its application through a case study involving the Armenian language. Our method, which is "portable" to many low-resource languages, not only mitigates the issue of data scarcity but also enhances the performance of ASR models for underrepresented languages.
