Das Forschungsprojekt untersucht den Verlauf von Lautwandel von der Entstehung bis zur Verbreitung, mit Schwerpunkten auf (1) dem Fortis/Lenis-Kontrast, (2) der experimentellen Prüfung einzelner in Lautwandeltheorien formulierter Hypothesen (wie der Neugewichtung akustischer Reize oder lexikalischer Diffusion) als auch (3) Anwendungsmöglichkeiten für die Sprachtechnologie.
Lay summary

Inhalt und Ziel des Forschungsprojekts

Das Vorhaben erforscht graduelle Änderungen in der Hierarchie akustischer Reize für den Fortis/Lenis-Kontrast (Verschluss- und Aspirationsdauer, Lösungsstärke, intrinsische Grundfrequenz) zwischen verschiedenen Generationen einer Sprecher­gemeinschaft, unter Berücksichti­gung möglicher regionaler Intonations­unterschiede.

Das Projekt verfolgt vier konkrete Ziele: (1) eine Analyse entstehender Trade-offs zwischen akustischen Reizen in diachronem Wandel; (2) eine weiterführende Unter­suchung der Auswirkung von Sprachkontakt und Interaktion auf Lautwandel mithilfe Agenten-basierter Modellierung; (3) Experimente zur Verbreitung des Lautwandels im Fortschritt durch lexikalische Diffusion; und (4) die Ausweitung der Analysen auf Dialektsynthese.

Wissenschaftlicher und gesellschaftlicher Kontext des Forschungsprojekts

Das trinationale DACH-Projekt verbindet in München entwickelte akustische, perzeptive und computergestützte Methoden zur Untersuchung der Produktions-Perzeptions­beziehung in Sprecher*innen aller Altersgruppen mit in Wien etablierten sprach­technologischen Methoden für Analysen österreichischer Varietäten und den in Zürich etablierten typologie-basierten Methoden zur Analyse schweizerdeutscher Varietäten. Langfristig zielt die Zusammenarbeit auf die Entwicklung eines Modells linguistischer (In-)Stabilität unter Berücksichtigung soziolinguistischer und experimentalphonetischer Daten.

Abstract

An extended investigation of the (in)stability of phonemic quantity in vowel plus consonant (VC) sequences in southern German varieties has provided new evidence (1) for the Bavarian VC timing system to be currently changing both in Austria and Germany primarily due to dialect levelling, (2) for the cross-generational stability of VC patterns in Swiss dialects, and (3) for the emergence of aspirated stops in younger speakers of Bavarian and Swiss dialects. The highly successful collaboration between the IPS (Munich), the ARI (Vienna), and the Phonetics Laboratory (Zurich) will be continued in this renewal proposal which builds upon the large database and the results obtained during the initial project. We now explore issues related to the trajectory of a sound change from its origin to its spread, with foci on (1) the voicing contrast, (2) the experimental testing of specific hypotheses formulated in sound change theories such as the reweighting of acoustic cues and lexical diffusion, and (3) the exploration of potential spin-offs from basic research to speech technology. The present proposal embraces the opportunity to examine for the first time gradual apparent-time changes in the hierarchy of acoustic cues to the phonemic voicing contrast such as closure and aspiration duration, the release strength, and intrinsic perturbations of fundamental frequency (Cf0) during the process of phonological change while considering potential effects of regional intonation differences on Cf0. The main aim is to contribute to a better understanding of the time course of phonological change. The proposal subsumes four specific aims: (1) to examine the development of trading relations between acoustic cues in diachronic change; (2) to further investigate how language contact and interaction trigger sound change by means of agent-based modelling; (3) to provide experimental evidence for the sound change in progress to be one of lexical diffusion; and (4) to expand the analyses to dialect synthesis. The innovation of the renewal proposal lies in the combination of phonetic analyses of speech production and perception data in the testing of linguistic theories, the application of computational methods to large-scale, cross-linguistic, apparent-time data (including data from older speakers and children), and the consideration of potential applications for speech technology. The proposed project links acoustic, perceptual, and computational methods for studying the production-perception-relation in speakers of different ages developed in Munich with methods from speech technology established at the ARI for analyses of Austrian regional varieties as well as with typology-based methods for quantifying Swiss varieties established in Zurich. In the long-term the collaboration aims at the development of a model of linguistic (in)stability that integrates sociolinguistic and experimental phonetic data.
