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.

本研究介绍了一种用于从有声读物生成ASR训练数据集的新型流程，以应对资源稀缺语言中自动语音识别系统性能较差的问题。该方法通过有效地对齐音频和相应的文本，并将其分割成适合ASR训练的长度，简化了资源稀缺语言中ASR系统的数据准备工作，并通过对亚美尼亚语的案例研究证明了其应用价值。这种方法可以适用于许多资源稀缺语言，不仅解决了数据匮乏问题，还提高了低资源语言的ASR模型性能。
