约鲁巴语是一种声调语言，其中轮廓声调（contour tones）持续构成正字法上的挑战。这些挑战在人名和词汇项中尤为显著，因为其传统拼写避免元音拉长，而元音拉长本可为第二个声调提供承载音节。一个特别值得关注的问题是，有一类名字的传统拼写不仅省略了声调信息，反而颠倒了该名字的含义，有时甚至表达了与名字本意相反的语义。本文描述了这一问题，说明了现有解决方案的不足，并提议采用抑扬符（caron）和扬抑符（circumflex）标记。这些符号在约鲁巴语音系学研究中早有先例，可追溯至Olmsted（1951），它们作为正字法约定用于单个元音上，以编码升调轮廓（rising contour tones）和降调轮廓（falling contour tones），从而首次使这些声调可通过标准键盘输入和计算文本处理来使用。该提议得到了WriteYoruba键盘和TTSYoruba语音合成器中实现的支撑，其架构和听者评估另文报告（Tubosun et al., 2026）。
英文摘要
Yorùbá is a tonal language in which contour tones pose persistent orthographic challenges. These are especially notable for personal names and lexical items whose conventional spellings avoid vowel lengthening that would otherwise provide a host syllable for the second tone. A particular concern is a class of names in which the conventional spelling does not just omit tonal information but inverts the meaning of said name, sometimes asserting the opposite of what the name intends. This paper describes the problem, illustrates the inadequacy of current solutions, and proposes the adoption of the caron and circumflex marks. These are symbols with precedent in Yorùbá phonological scholarship since Olmsted (1951), used as orthographic conventions on single vowels to encode rising and falling contour tones, making them accessible for the first time through standard keyboard input and computational text processing. The proposal is supported by an implementation in the WriteYoruba keyboard and the TTSYoruba speech synthesizer, whose architecture and listener evaluation are reported separately (Tubosun et al., 2026).
