A hybrid PARAFAC and principal-component model of tongue configuration in vowel production is presented, using a corpus of German vowels in multiple consonant contexts (fleshpoint data for seven speakers at two speech rates from electromagnetic articulography). The PARAFAC approach is attractive for explicitly separating speaker-independent and(More)
Velar consonants often show an elliptical pattern of tongue movement in symmetrical vowel contexts, but the forces responsible for this remain unclear. We here consider the role of overpressure (increased intraoral air pressure) behind the constriction by examining how movement patterns are modified when speakers change from an egressive to ingressive(More)
Digital video filming of the thryroid prominence was used to measure larynx height in German vowels, with focus on contrasts involving front unrounded, front rounded and back rounded vowels. The study aimed to provide a foundation for interpreting the acoustic consequences of articulatory manoeuvres not only at the larynx but also elsewhere in the vocal(More)
In Articulatory Phonology the jaw is not controlled individually but serves as an additional articulator to achieve the primary constriction. In this study the timing of jaw and tongue tip gestures for the coronal consonants /U, 5, V, F, P, N/ is analysed by means of EMMA. The findings suggest that the tasks of the jaw for the fricatives are to provide a(More)
This study investigates prosodic planning in a reading task in German. We analyse how the utterance length and syntactic complexity of an upcoming sentence affect two acoustic parameters (pause duration and the initial fundamental frequency peak) and two respiratory parameters (inhalation depth and inhalation duration). Two experiments were carried out. In(More)
The tense and lax vowels of German were compared, based on an analysis of the duration, amplitude and velocity characteristics of lip and tongue movement. This study examined firstly whether they show different patterns of compression over changes in speech rate, and secondly whether velocity profiles would reveal evidence of different underlying control(More)
The trough effect is a phenomenon occuring in a VCV-sequence, where both vowels are identical and the consonant is produced with an articulator which is thought to be unspecified for vowel production. It can be described as a momentary deactivation of tongue movement when the consonant is a bilabial. Several interpretations have been given to the causes and(More)
