Abstract 摘要
The Dilu dialect (spoken in Mengshan, Guangxi) shows, disparity in the categorization of phonation types in phonetic and phonological analyses. While the phonological analysis proposes that Dilu operates with two phonation types, i.e. creaky and modal, phonetic facts show a three-way distinction, i.e. creaky, male modal and female modal. In this paper acoustic features are investigated for modal and creaky voices in Dilu.1 In particular, the parameters of Open Quotient (OQ) and Speed Quotient (SQ) are examined. We discuss whether it is necessary and possible for female and male modal voices to collapse into one category to serve the purpose of phonological transcription. Finally, based on an independent five-level tone scale, we propose a tone transcription system for languages that have various phonation types.

从语音学角度看，蒙山底路话中存在三个嗓音类型：挤喉嗓音，男性正常嗓音和女性正常嗓音，从音位学角度来看，只存在挤喉嗓音和正常嗓音的对立。根据蒙山底路话声调系统的这一特性，在本文中我们分析了蒙山底路话声调系统中挤喉嗓音的声学特征，根据开商和速度商参数，讨论了蒙山底路话挤喉嗓音的发声模式；还讨论了在音位处理过程中，男女正常嗓音转换的可能性和必要性；提出了在多声域语言中根据不同发声类型用不同的五度标尺的标调框架。
