“…While a growing body of research uses forced-alignment as the first step in acoustic analysis (e.g., Clayards & Doty, 2011;DiCanio, Nam, Amith, García, & Whalen, 2015;Labov, Rosenfelder, and Fruehwald, 2013;Renwick, Baghai-Ravary, Temple, & Coleman, 2013;Yuan & Liberman, 2011b), we also compared the results of the automatic alignment with results from a subset of data in which the /l/ boundaries were hand-adjusted. The subset of data consisted of 276 tokens (approximately 50%) selected randomly from Experiment 2 (e.g., freely, Healy, mealy and velum, realest, kneeless).…”

It is uncontroversial that, in many varieties of English, the realization of /l/ varies depending on whether /l/ occurs word-initially or word-finally. The nature of this effect, however, remains controversial. Previous analyses alternately analyzed the variation as darkening or lightening, and alternately found evidence that the variation involves a categorical distinction between allophones or a gradient scale conditioned by phonetic factors. We argue that these diverging conclusions are a result of the numerous factors influencing /l/ darkness and differences between studies in terms of which factors are considered. By controlling for a range of factors, our study demonstrates a pattern of variability that has not been shown in previous work. We find evidence of morpheme-final darkening and morpheme-initial lightening when compared to a baseline of morpheme-internal /l/. We also find segmental effects such that, in segmental contexts which independently darken /l/, one can observe /l/ lightening, and contexts which independently lighten /l/ can make lightening effects undetectable. Morphological and prosodic effects are hence sometimes trumped by segmental context. Once contextual effects are controlled for, there is evidence both for morphologically-conditioned /l/-darkening and for morphologicallyconditioned /l/-lightening, both of which can be understood as a result of prosodic differences reflecting morphological junctures.

While Mixtec languages are well-known for their tonal systems, there remains relatively little work focusing on their consonant inventories. This paper provides an in-depth phonetic description of the consonant system of the Yoloxóchitl Mixtec language (Oto-Manguean, ISO 639-3 code xty), a Guerrero Mixtec variety. The language possesses a number of contrasts common among Mixtec languages, such as voiceless unaspirated stops, prenasalized stops, and a strong tendency for words to conform to a minimally bimoraic structure. Using a controlled set of data, we focus on how WORD SIZE and WORD POSITION influence the acoustic properties of different consonant types. We examine closure duration, VOT, and formant transitions with the stop series, spectral moments with the fricative series, the timing between oral and nasal closure with the prenasalized stop series, and both formant transitions and qualitative variability with the glide series. The general effect of WORD SIZE is discussed in relation to work on POLYSYLLABIC SHORTENING

“…Herein, we document the nest architecture, nesting substrate, and local abundance of six species of stingless bees from Yoloxóchitl. We also report on Indigenous knowledge of their behavior, uses, management practices, nomenclature, and classification by speakers of Yoloxóchitl Mixtec, a rapidly disappearing language currently spoken by only about 5000 people (Castillo 2007;DiCanio et al 2015). Based on biological and ethnographic information, we quantitatively assess the relative cultural importance of each bee species and explore its relationship with their local abundance.…”

Nesting ecology and the cultural importance of stingless bees to speakers of Yoloxóchitl Mixtec, an endangered language in Guerrero, Mexico

Stingless bees (Apidae: Meliponini) are major pollinators of many wild and cultivated plants, and both indigenous and non-indigenous populations use their products for diverse purposes including food, crafts, and medicine. However, many aspects of both stingless bee nesting ecology and traditional knowledge of these culturally significant bees by diverse human populations remain unknown or poorly documented. We report on the nest architecture, nesting substrate, host plants, and local abundance of stingless bees occurring in Yoloxóchitl, one of several indigenous villages that speak Yoloxóchitl Mixtec, an endangered language on the Pacific Coast of the state of Guerrero. We also document local Indigenous nomenclature, classification, and use of these bees as well as traditional management practices and knowledge of their behavior. Lastly, we offer a preliminary quantitative analysis of the relative cultural importance of each bee species and explore the relationship of traditional ecological knowledge to these species.
