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.

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。从发音和声学角度来看，这一声音类别具有不同的复杂特征。本研究通过分析一种尚未从声学角度考虑内爆音的语言的声学特征来探索声音类别：Shimaore，马约特岛使用的班图-萨巴基语。具体来说，它通过 H1 * –H2 *、谐波噪声比 (HNR) 在语音起始时间 (VOT)、基频、振幅和语音质量方面比较双唇爆破音 /b/ 和双唇内爆音 /ɓ / ）和倒谱峰突出（CPP）。分析表明，内爆音的 VOT 比爆破音短。在口腔闭合和元音开始时，振幅和 f0 高于爆破音。H1 * –H2 *值与 HNR 和 CPP 值一起读取表明 Shimaore 中的内爆音具有声门收缩。对于内爆变异的问题，探讨了一些个体差异。讨论了马约特岛社会语音学研究的意义以及对内爆音的一般意义。
