Smiles can be conveyed to listeners via speech signals: A case study with Japanese labiodentalization
One long-standing question in speech communication research concerns the extent to which an emotional state is encoded in the acoustic signal and conveyed to the listeners. To address this question, we deployed a recent finding in Japanese, in which speakers replace bilabial sounds (e.g. [b]) with labiodental sounds (e.g. [v]) when speaking with a smile. Experiment 1 used stimuli recorded by two professional voice actors under four conditions cro…
The Interaction Between Tone and Duration in Du’an Zhuang
This research investigates the tone system of an understudied language, Du’an Zhuang and its interaction with duration. Cross-linguistically, tones tend to be less complex in shorter duration contexts. In Du’an Zhuang, syllable type provides these contexts: There are six contrastive tones among unchecked syllables with longer rhyme duration, but this is reduced to four tones in shorter duration checked syllables. Acoustic analyses of f0 and durat…
The Non-Coalescence of /h/ and Incomplete Neutralization in South Jeolla Korean
This study examines articulatory and acoustic data in order to investigate the non-coalescence of /h/ in South Jeolla. Seoul Korean speakers produce /pap/ “rice” followed by /hana/ “one” as [pa.p h a.na] with the coalescence of /p/ and /h/; this is called an aspiration merger. In South Jeolla Korean, this merger may be blocked, as in cases where speakers produce /pap+hana/ as [pa.ba.na]. Electroglottographic (EGG) data indicate the existence of t…
Segmental information drives adult bilingual phrase segmentation preference
In two artificial language learning experiments with four groups of highly proficient Basque-Spanish bilinguals and two groups of Spanish monolinguals, we examine the cues that allow adult listeners to parse new input into phrases. In addition, we investigate which factors lead bilinguals to switch between the segmentation strategies characteristic of their two languages. We show that segmental information drives bilinguals’ choice of a segmentat…
Decolonial Sketches and Intercultural Approaches to Truth: Corporeal Experiences and Testimonies of Indigenous Women in Colombia
This article explores the corporeal and testimonial memories of a group of female indigenous ex-combatants and victims in the Colombian Caribbean and Amazon. Although these groups have often been analyzed in the transitional justice literature, our primary objective is to analyze two local processes for retrieving indigenous women's memories and possible feminist participatory action research methodologies in the Colombian postconflict context. W…
English compound and non-compound processing in bilingual and multilingual speakers: Effects of dominance and sequential multilingualism
This article reports on a study investigating the relative influence of the first language and dominant language (L1) on second language (L2) and third language (L3) morpho-lexical processing. A lexical decision task compared the responses to English NV-er compounds (e.g. taxi driver) and non-compounds provided by a group of native speakers and three groups of learners at various levels of English proficiency: L1 Spanish – L2 English sequential b…
Roughness Minimization Through Automatic Intonation Adjustments
We have created a reintonation system that minimizes measured roughness of parallel sonorities as they are produced. Intonation adjustments are performed by finding, within a user-defined vicinity, a combination of fundamental frequencies that yields minimal roughness. The vicinity imposition limits pitch drift and eases real-time computation. Prior knowledge of the tones played and timbres used is not used for execution of the algorithm. We test…
