摘要

随着时间的推移,内爆辅音引起了研究人员的注意,部分原因是它们在世界语言中相对罕见,部分原因是它们独特的侵入气流。从发音和声学的角度来看,这个声音类别具有不同的复杂特征。本研究通过分析一种尚未被声学研究的内爆语言的声学特征来探索声音类别:马约特岛的班图-萨巴基语Shimaore。具体而言,本文通过H1* -H2 *、谐波噪声比(HNR)和倒谱峰突出(CPP),比较了双侧爆破音/b/和双侧爆破音/ h /在起音时间(VOT)、基频、幅度和语音质量方面的差异。分析表明,内爆药的VOT比爆炸药短。在口腔闭合和元音起始时,振幅和f0高于爆破音。H1* -H2 *值与HNR和CPP值一起读数提示Shimaore内爆声门收缩。对于内爆的变异问题,探讨了一些个体差异。关于马约特社会语音研究的含义以及对内爆的一般含义进行了讨论。

The acoustic characteristics of implosive and plosive bilabials in Shimaore
Implosive consonants have drawn the attention of researchers over time, partially due to their relative rarity in the world’s languages, and partially due to their unique ingressive air flow. This sound category has varying complex features from an articulatory and acoustic perspective. This study explores the sound category by analyzing the acoustic features of a language whose implosives have yet to be acoustically considered: Shimaore, a Bantu-Sabaki language spoken in Mayotte. Specifically, it compares the bilabial plosive /b/ and the bilabial implosive /ɓ/ in terms of Voice Onset Time (VOT), fundamental frequency, amplitude, and voice quality via H1*–H2*, harmonics-to-noise ratios (HNR), and cepstral peak prominence (CPP). Analyses show that VOT is shorter for implosives than for plosives. At oral closure and vowel onset, amplitude and f0 are higher than plosives. H1*–H2* values read alongside HNR and CPP values suggest that implosives in Shimaore have glottal constriction. Some individual differences are explored for question of variation in implosives. Implications regarding sociophonetic studies in Mayotte as well as general implications for implosives are discussed.

期刊介绍: The Journal of the International Phonetic Association (JIPA) is a forum for work in the fields of phonetic theory and description. As well as including papers on laboratory phonetics/phonology and related topics, the journal encourages submissions on practical applications of phonetics to areas such as phonetics teaching and speech therapy, as well as the analysis of speech phenomena in relation to computer speech processing. It is especially concerned with the theory behind the International Phonetic Alphabet and discussions of the use of symbols for illustrating the phonetic structures of a wide variety of languages. JIPA now publishes online audio files to supplement written articles Published for the International Phonetic Association
