近年来，有效的语言文档问题，尤其是在少数群体和濒危语言方面的问题，在该领域的几个主要资金计划和其他人类语言技术计划中都有了重要的意见。描述了非洲语言的注释语言的词汇变化。词汇音调的上下文变化（包括自动下降，降落和音调同化），但传感器也可以在振动性的“计量语音学”中直观地满足韵律概念的阐释（迭代性过渡）。在非洲词汇语言语言中形式化类型学差异的价值和自动产生标记增强的实用价值以基于和解的语料库分析对于音调建模的基本频率预测。
The issue of efficient language documentation, particularly with regard to minority and endangered languages, has gained in importance in recent years, as witnessed by several major funding programmes and other human language technology initiatives in the field. An application of finite state technologies to the processing of lexical tone variation in annotated corpora of African languages is described. It is shown that finite state transducers can be constructed which not only provide adequate models for contextual variation in lexical tone (including automatic downstep, downdrift, and tonal assimilations), but also that the transducers provide intuitively satisfying explications of prosodic concepts in ‘metrical phonology’ in terms of oscillations (iterative transitions). The technique has both theoretical value in formalising typological differences in African lexical tone languages and practical value in automatically generating markup enhancements for concordance-based corpus analysis and for fundamental frequency prediction in pitch modelling. 1.
