Areal Typology of glottalization in the languages of the Caucasus and Transcaucasus

The project focuses sound inventories containing sounds with a glottalic airstream mechanism, specifically in the languages of the Caucasus (currently included: Tsez, Bezhta, Ingush, Chechen, Dargwa, Khwarshi, Avar, Karata, Lak, Kumyk, Georgian, Svan, Kabardian, Circassian) and Transcaucasus (e.g. Kurdish, Armenian, Azerbaidjani) with the aim to explore to nature of transitional expressions of features [Sven Grawunder,  Don Stilo (MPI EvA Leipzig), Madzhid Khalilov (AcadSc Makhachkala, Daghestan), Adrian Simpson (U Jena)] 

Labio-velar stops in Yoruba

Yoruba is a major language of Nigeria and uses double-articulated stop sounds (gb, kp) that are wide spread also among its neighbors. The project aims at fine grained details by means of articulatory (high-speed video, ultra-sound, electro-glottographic), aerodynamic, acoustic and perceptual data in order to understand the particular nature of these sounds and how they are involved in sound change. [Sven Grawunder, Leonardo Lancia, Daniel Voigt]

Pharyngealization in German dialects (Swabian, Thuringian and Saxonian)

Usually such phonetic descriptions like ATR (Advanced Tongue Root) and pharyngealization are associated with languages in Africa (e.g. Aka, Oko, Ewe) or semitic languages. But a closer look at the so called "dark" vowels in some German dialects reveals the universal nature of the underlying articulation strategies ongoing ultrasound data collection, subjects needed! (Sven Grawunder)

Phonetically motivated sound change in onset clusters of German

We investigate the [kl>tl] shift of initial consonant clusters in Saxon and other German dialects. The shift has been observed in other Germanic languages but also languages all over the world. Current research focuses particular on its distribution in German as well as on articulatory and perceptual traits [Sven Grawunder, Leonardo Lancia, Juliette Blevins[CUNY]). 

Phonetics and Phonology of South Munda languages

Gta'(Didayi) and Bonda (Remo) belong to the southern group of Munda languages of the Austoasiatic language family spoken in India. The small-scale fieldwork documentation project of Gta' and Bonda texts is a joint cooperation between Sven Grawunder and Arun Gosh from Burdwan University (India).

Phonetics and Tonology of Ket

Ket is a severely endangered language in Western Siberia. It is the last survivor of its group of Yeniseic languages and the only known language of North Asia which has lexical tone. The joint work between Sven Grawunder and Edward Vaijda from Western Washington U focuses the phonology and tonology of Ket which is unique in Northern Eurasia.

'Sound Comparisons': New Tools and Resources for Exploring Language Family Diversity on the Web

This research project creates ‘hover to hear’ websites to allow users to hear and compare instantaneously online the precise differences in how specific cognate words are pronounced from one region to the next across an entire language family at a time. The database is that of the related research theme on Language Relatedness and Divergence, which in this accompanying project is turned into an online resource not just for researchers in linguistics, but also for the people who actually speak the language varieties concerned. It already covers many thousands of individual word recordings and phonetic transcriptions from scores of regional accents, dialects and languages across both Europe and the Andes. [more]

Sounds of the Andean Languages

Within the broader framework of the above Sound Comparisons research theme, this is a specific project to document and quantify the degree of divergence in phonetics of the major language families of the Andes, particularly Quechua, Aymara and Mapudungun (‘Mapuche’). Our comparative recordings and transcriptions will be made available on the much revised and expanded Sounds of the Andean Languages website, to be relaunched in spring 2013. [more]

Vilela (Lule Vilela) phonetics and phonology

What happens if you would be the last speaker of a language? Vilela is such a moribund language spoken in the Chaco area of Argentina. The scarce records point to interesting phonetic-phonemic variation in Vilela. Detailed phonetic analyses of recordings of the last speaker(s) (Sven Grawunder, Lucia Gallucio (U Buenos Aires) and Juliette Blevins (MPI EVA)).

West !Xoon (Taa) phonetics and phonology

This joint work with Christfried Naumann, MPI EvA, Leipzig [link] sets its main focus on phonation types, glottalization and laryngeal-velar coordination in Western !Xóõ a language of the Taa group (KhoeSan). (Sven Grawunder)

Interactions across time scales in speech perception

Flexibility is a key property of our perceptual system due to the richness and to the relative unpredictability of our environment. We investigate how flexible behavior can emerge from the interaction between fast perceptual dynamics, which adapt our perception to the environment "as fast as possible", with slower processes like habituation to the stimuli and learning. [more]

Laryngealization: characterization and interaction with other features

We study the functioning of the larynx in the production of glottal stops and in the production of laryngealized voicing via an original approach to the quantification of this phonetic feature in running speech. [more]

Modeling speech dynamics trough recurrences

If we want to obtain a systematic description of a language in the terms of underlying dynamics we need a systematic way to extract information about these dynamics from the speech signals. [more]

Phonetic constraints on lexical items

Why some sequences of sounds are more frequent than others in world's languages? Our assumption is that physiological constraints are mainly responsible for these distributional biases but that, when phonetic constraints are observed in the context of specific languages, phonetic factors interact with the structural features of these languages. [more]

Statistical modeling of trajectories and shapes applied to speech

Speech unfolds in time and there are many reasons to move away from a static characterization of speech patterns. This is a technical issue with deep theoretical implications, because static characterizations are not informative enough if we want to study speech in a dynamical framework. [more]

Phonetic and phonological description of Even dialects (with a focus on acoustic vowel properties and vowel harmony)

The project is dedicated to the phonetics and phonology of Even, a Tungusic language spoken in eastern Siberia. In her dissertation, Natalia Aralova presents field data from two distant dialects, respectively pertaining to the village of Sebian-Küöl in Yakutia (Western dialect) and the district of Bystraia on the Kamchatka Peninsula (Eastern dialect).
