中文摘要 AI 辅助
ÌròyìnSpeech 是一个 42 小时、80 位说话人的约鲁巴语朗读语音语料库，其音频自 2024 年起由 ELRA 分发。本文描述了其文本组件的发布：24,905 条独特的、人工验证的、带声调标记的约鲁巴语句子（275,897 个词元；15,687 个词型），这些句子于 2022 年作为录音提示语整理而成。其中约 11,000 条句子改编自开放许可的新闻材料；其余句子为内部撰写，以扩大覆盖面，超越现有约鲁巴语语料库中占主导地位的宗教翻译内容。每个句子都经过人工检查声调标记的准确性，并编辑以确保朗读清晰、语域中性，且经过本地化处理，使非约鲁巴语的人名和地名以约鲁巴语形式出现。准备发布文本时，发现了影响超过 60% 行（同一字母的预组合形式和分解形式在单个句子中同时出现）的系统性 Unicode 规范化失败，我们对此进行了记录和纠正。该语料库支持变音符号恢复、字素到音素转换、TTS 前端开发和正字法研究，并可作为新录音的验证提示集。
英文摘要
ÌròyìnSpeech is a 42-hour, 80-speaker Yorùbá read-speech corpus whose audio has been distributed by ELRA since 2024. This paper describes the release of its text component: 24,905 unique, hand-verified, tone-marked Yorùbá sentences (275,897 tokens; 15,687 types), curated in 2022 as recording prompts. Roughly 11,000 sentences were adapted from openly licensed news material; the remainder were written in-house to broaden coverage beyond the religious translation that dominates existing Yorùbá corpora. Every sentence was checked by hand for tone-mark accuracy, edited for read-aloud clarity and a neutral register, and localised so that non-Yorùbá personal and place names appear in Yorùbá form. Preparing the text for release surfaced systematic Unicode normalisation failures affecting more than 60% of lines (with precomposed and decomposed forms of the same letter co-occurring within single sentences) which we document and correct. The corpus supports diacritic restoration, grapheme-to-phoneme conversion, TTS front-end development and orthographic research, and serves as a validated prompt set for new recording.
