ISSAI Kazakh Speech Corpus v2.0

KSC2 is the first industrial-scale open-source Kazakh speech corpus for automatic speech recognition research and development. Our corpus subsumes two previously presented corpora: 1) Kazakh speech corpus (KSC) and 2) Kazakh text to-speech 2 (KazakhTTS2). We also provide additional data from other sources, including television news, television and radio programs, parliament speeches, and podcasts. Our corpus, which we have named KSC2, contains over a thousand hours of high-quality transcribed data, which is triple the size of KSC. KSC2 was manually transcribed with the help of native Kazakh speakers and validated via preliminary speech recognition experiments on various evaluation sets. Moreover, it contains utterances with Kazakh-Russian code-switching, a conversational practice common among Kazakh speakers.

KSC2是首个面向自动语音识别（Automatic Speech Recognition）研发的工业级开源哈萨克语语音语料库。本语料库整合了此前发布的两个语料库：1）哈萨克语语音语料库（KSC）；2）哈萨克语文本到语音2（KazakhTTS2）。此外，我们还从其他渠道补充了数据，涵盖电视新闻、电视与广播节目、议会演讲以及播客内容。我们将该语料库命名为KSC2，其包含超过1000小时的高质量带标注转录数据，体量是KSC的三倍。KSC2由哈萨克语母语使用者协助完成人工转录，并通过在多个评估集上开展的初步自动语音识别实验完成了有效性验证。此外，该语料库还包含哈萨克语-俄语语码转换语句，这是哈萨克语使用者中常见的会话现象。
