“…This is in line with highlighting strategies reported for prosodic prominence in German [ 38 ]. As shown before by Thies et al [ 57 ], hyper-articulation of vowels would be expected. However, no spatial modifications were found with respect to more peripheral vowel formant frequencies (no hyper-articulation).…”

“…It postulates that prominence marking can vary from speakers with PD compared to healthy controls [ 55 , 56 ]. Moreover, a recent study by Thies and colleagues [ 57 ] showed that patients with PD can mark prosodic prominence by modulating f 0 , intensity and vowel articulation in prominent positions, but the prosodic modifications are less efficient than in healthy control speakers. While patients performed with a reduced vowel space in terms of hypoarticulated vowels, they hyperarticulated prosodic parameters such as intensity and tonal range.…”

“…Prominence marking: Patients with PD can manipulate f0, intensity and acoustic vowel durations in accented syllables to express local prominence [ 35 , 57 ]. Patients with PD adjust the acoustic vowel space to signal prominence (hyper-articulation of vowels) [ 57 ]. In prominent positions, articulatory tongue body movements (related to vowel production) are longer (increase in movement duration) and larger (increase in movement amplitude) [ 54 ].…”

The present study investigates speech changes in Parkinson’s disease on the acoustic and articulatory level with respect to prosodic prominence marking. To display movements of the underlying articulators, speech data from 16 patients with Parkinson’s disease were recorded using electromagnetic articulography. Speech tasks focused on strategies of prominence marking. Patients’ ability to encode prominence in the laryngeal and supra-laryngeal domain is tested in two conditions to examine the influence of motor performance on speech production further: without dopaminergic medication and with dopaminergic medication. The data reveal that patients with Parkinson’s disease are able to highlight important information in both conditions. They maintain prominence relations across- and within-accentuation by adjusting prosodic markers, such as vowel duration and pitch modulation, while the acoustic vowel space remains the same. For differentiating across-accentuation, not only intensity but also all temporal and spatial parameters related to the articulatory tongue body movements during the production of vowels are modulated to signal prominence. In response to the levodopa intake, gross motor performance improved significantly by 42%. The improvement in gross motor performance was accompanied by an improvement in speech motor performance in terms of louder speech and shorter, larger and faster tongue body movements. The tongue body is more agile under levodopa increase, a fact that is not necessarily detectable on the acoustic level but important for speech therapy.
