Am Beispiel der polyfunktionalen Mehrworteinheit <was weiß ich> wird das Zusammenspiel von pragmatischer und phonetischer Ausdifferenzierung in Pragmatikalisierungsprozessen untersucht. Hierzu werden spontan-sprachliche Belege aus dem Korpus „Deutsch heute“ analysiert. Die beobachtete phonetische Variationsbreite deutet auf eine komplexe Beziehung zu den jeweiligen pragmatischen Funktionen hin.
Sogenannte „Pragmatikalisierte Mehrworteinheiten“ sind im Deutschen hochfrequent und unterliegen bisweilen tiefgreifenden phonetischen Reduktionsprozessen. Diese können Realisierungsvarianten hervorbringen, die in der Rückschau auf mehr als eine lexematische Ursprungsform zurückführbar sind. Die vorliegende Studie untersucht mit [ˈzɐmɐ] einen besonders prägnanten Fall dieser Art anhand eines Perzeptionsexperimentes.
A "polyglottal" speech synthesis - modifications for a replica of Kempelen's speaking machine
(2019)
This report presents a corpus of articulations recorded with Schlieren photography, a recording technique to visualize aeroflow dynamics for two purposes. First, as a means to investigate aerodynamic processes during speech production without any obstruction of the lips and the nose. Second, to provide material for lecturers of phonetics to illustrates these aerodynamic processes. Speech production was recorded with 10 kHz frame rate for statistical video analyses. Downsampled videos (500 Hz) were uplodad to a youtube channel for illustrative purposes. Preliminary analyses demonstrate potential in applying Schlieren photography in research.
Ph@ttSessionz and Deutsch heute are two large German speech databases. They were created for different purposes: Ph@ttSessionz to test Internet-based recordings and to adapt speech recognizers to the voices of adolescent speakers, Deutsch heute to document regional variation of German. The databases differ in their recording technique, the selection of recording locations and speakers, elicitation mode, and data processing.
In this paper, we outline how the recordings were performed, how the data was processed and annotated, and how the two databases were imported into a single relational database system. We present acoustical measurements on the digit items of both databases. Our results confirm that the elicitation technique affects the speech produced, that f0 is quite comparable despite different recording procedures, and that large speech technology databases with suitable metadata may well be used for the analysis of regional variation of speech.
This paper outlines the generation process of a specifi computational linguistic representation termed the Multilingual Time Map, conceptually a multi-tape finit state transducer encoding linguistic data at different levels of granularity. The fi st component acquires phonological data from syllable labeled speech data, the second component define feature profiles the third component generates feature hierarchies and augments the acquired data with the define feature profiles and the fourth component displays the Multilingual Time Map as a graph.
In this paper I explore the theoretical significance of phonologically conditioned gaps in word formation. The data support the original approach to gaps in Optimality Theory proposed by Prince & Smolensky (1993), which crucially involves MPARSE as a ranked and violable constraint. The alternative CONTROL model proposed by Orgun & Sprouse (1999) is found to be inadequate because of lost generalisations and technical flaws. It is shown that a careful distinction between various morphophonological effects (e.g. paradigm uniformity effects, phonological repair and ‘stem selection’) is necessary to shed light on the morphology–phonology interface. The data investigated here support affixspecific constraint rankings, but argue against any stratal organisation of morphology.
This study investigates high vowel laxing in the Louisiana French of the Lafourche Basin. Unlike Canadian French, in which the high vowels /i, y, u/ are traditionally described as undergoing laxing (to [I, Y, U]) in word-final syllables closed by any consonant other than a voiced fricative (see Poliquin 2006), Oukada (1977) states that in the Louisiana French of Lafourche Parish, any coda consonant will trigger high vowel laxing of /i/; he excludes both /y/ and /u/ from his discussion of high vowel laxing. The current study analyzes tokens of /i, y, u/ from pre-recorded interviews with three older male speakers from Terrebonne Parish. We measured the first and second formants and duration for high vowel tokens produced in four phonetic environments, crossing syllable type (open vs. closed) by consonant type (voiced fricative vs. any consonant other than a voiced fricative). Results of the acoustic analysis show optional laxing for /i/ and /y/ and corroborate the finding that high vowels undergo laxing in word-final closed syllables, regardless of consonant type. Data for /u/ show that the results vary widely by speaker, with the dominant pattern (shown by two out of three speakers) that of lowering and backing in the vowel space of closed syllable tokens. Duration data prove inconclusive, likely due to the effects of stress. The formant data published here constitute the first acoustic description of high vowels for any variety of Louisiana French and lay the groundwork for future study on these endangered varieties.
American English and German AI, AU observed in cognates such as Wein, wine, Haus, house are usually treated on a par, represented with the same initial vowel (cf. [ai], [au] for Am. Engl, and German [1]). Yet, acoustic measurements indicate differences as the relevant trajectories characteristically cross in Am. Engl, but not in German. These data may indicate consistency with the same initial target for these diphthongs in German, supporting the choice of the same Symbol /a/ in phonemic representation, as opposed to distinct targets (and distinct initial phonemes) in American English.
Die erfolgreiche Wiederverwendung gesprochener Korpora muss fachspezifischen Evaluationskritierien genügen und erfordert daher eine flexible Korpusarchitektur, die durch multirepräsentationale (Verfügbarkeit eines akustischen Signals und einer Transliteration) und multisituationale Daten (Variabilität von Situationen bzw. Aufgaben) gekennzeichnet ist. Diese Kriterien werden in einer Fallstudie zur /eː/-Diphthongisierung polnischer Deutschlerner/-innen angewendet und diskutiert. Die Fallstudie repliziert die Ergebnisse der /eː/-Diphthongisierung bei Bildbenennungen von Nimz (2016). Vor der Wiederverwendung werden weitere fachspezifische Evaluationskriterien überprüft, wie Multisituationalität, Aufnahmequalitäten, Erweiterbarkeit, vorhandene Metadaten und vorhandene Dokumentation. Nach der Replikationsstudie werden die Herausforderungen für eine Umsetzung der Wiederverwendung bezüglich Datenmanagement, Workflows und Data Literacy in Forschungs- und Lehrkontexten diskutiert.
