Purpose
In current clinical practice, intelligibility of dysarthric speech is commonly assessed by speech-language therapists (SLTs), in most cases by the therapist caring for the patient being diagnosed. Since SLTs are familiar with dysarthria in general and with the speech of the individual patient to be assessed in particular, they have an adapt...
Purpose
Despite extensive research into communication-related parameters in dysarthria, such as intelligibility, naturalness, and perceived listener effort, the existing evidence has not been translated into a clinically applicable, comprehensive, and valid diagnostic tool so far. This study addresses Communication-Related Parameters in Speech Diso...
Citation: Aichert, I.; Lehner, K.; Falk, S.; Späth, M.; Franke, M.; Ziegler, W. Abstract: In the present study, we investigated if individuals with neurogenic speech sound impairments of three types, Parkinson's dysarthria, apraxia of speech, and aphasic phonological impairment, accommodate their speech to the natural speech rhythm of an auditory m...
Assessing the impact of dysarthria on a patient's ability to communicate should be an integral part of patient management. However, due to the high demands on reliable quantification of communication limitations, hardly any formal clinical tests with approved psycho-metric properties have been developed so far. This study investigates a web-based a...

This article describes the design of KommPaS, a web-based tool for the clinical assessment of communication impairment in persons with dysarthria. KommPaS (the German acronym for Communication-related Parameters in Speech Disorders) allows clinicians to recruit laypersons via crowdsourcing for the evaluation of samples of dysarthric speech with reg...
Purpose
Independent laypersons are essential in the assessment of intelligibility in persons with dysarthria (PWD), as they reflect intelligibility limitations in the most ecologically valid way, without being influenced by familiarity with the speaker. The present work investigated online crowdsourcing as a convenient method to involve lay people...
Purpose
The clinical assessment of intelligibility must be based on a large repository and extensive variation of test materials, to render test stimuli unpredictable and thereby avoid expectancies and familiarity effects in the listeners. At the same time, it is essential that test materials are systematically controlled for factors influencing in...
In a comprehensive dysarthria assessment, different perspectives should be adopted. In addition to clinical experts, laypersons should be included as evaluators. In particular, laypersons are most important as informants with regard to communication-related parameters, such as intelligibility and naturalness. The article highlights the methodologic...
Rationale: Treatment of aphasia is still challenging for clinicians and patients. So far, there is proven evidence for “face-to-face” speech therapy. However, the digital age potentially offers new and complementary strategies that may add to treatment outcome in a cost-effective way. Neolexon® is a commercial tablet-based software for treatment of...
Rationale: In the approach presented here, adult apraxia of speech (AoS) is understood as a disorder affecting the language-specific motor patterns a speaker acquires during childhood and adolescence. The phonological factors that influence articulatory accuracy in AoS reflect the relative vulnerability of their accompanying motor planning variable...
Purpose
Earlier investigations based on word and sentence repetition tasks had revealed that the most prevalent metrical pattern in German (the trochee)—unlike the iambic pattern—facilitates articulation in patients with apraxia of speech (AOS; e.g., Aichert, Späth, & Ziegler, 2016), confirming that segmental and prosodic aspects of speech producti...
