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)
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)
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)
Intra-gestural and inter-gestural coordination in German word-initial consonant clusters /kl, kn, ks, pl, ps/ is investigated in four speakers by means of EMA as a function of segmental make-up and prosodic variation, i.e. prosodic boundary strength and lexical stress. Segmental make-up is shown to determine the extent of articulatory overlap of the(More)
For the speech ability assessment of glossectomee patients, dynamic MRT was used in order to obtain real time imaging of articulatory movements. At the present state, the method is best suited for continuous consonants, but it can be used for the evaluation of any speech sound. In this study, pre-and postoperative consonant articulation of eight patients(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)
The PARAFAC method of factor analysis was used to investigate patterns of tongue shaping in a corpus of 15 German vowels spoken in 3 consonant contexts by 7 speakers at 2 speech rates, using data from electromagnetic articulography. A two-factor model was extracted, giving a succinct, speaker-independent characterization of the German vowel space and of(More)
