“…In considering the effects of cueing strategies on languages other than English, one might expect universal benefits to intelligibility from cues to increase vocal intensity, such as ‘strong voice’, because of the universality of motor impairments (Pinto et al . 2017) and the improvements in audibility and spectral tilt, among other acoustic benefits resulting from louder speech reported in English speakers (Tjaden et al . 2014).…”

Background: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children's intelligibility deficits and negatively affecting their social participation. However, the effects of speech-treatment strategies for improving intelligibility in this population are understudied, especially for children who speak languages other than English. In a cueing study on English-speaking children with dysarthria, acoustic variables and intelligibility improved when the children were provided with cues aimed to increase articulatory excursion and vocal intensity. While French is among the top 20 most spoken languages in the world, dysarthria and its management in French-speaking children are virtually unexplored areas of research. Information gleaned from such research is critical for providing an evidence base on which to provide treatment. Aims: To examine acoustic and perceptual changes in the speech of French-speaking children with dysarthria, who are provided with speech cues targeting greater articulatory excursion (French translation of 'speak with your big mouth') and vocal intensity (French translation of 'speak with your strong voice'). This study investigated whether, in response to the cues, the children would make acoustic changes and listeners would perceive the children's speech as more intelligible. Methods & Procedures: Eleven children with dysarthria due to CP (six girls, five boys; ages 4;11-17;0 years; eight with spastic CP, three with dyskinetic CP) repeated pre-recorded speech stimuli across three speaking conditions (habitual, 'big mouth' and 'strong voice'). Stimuli were sentences and contrastive words in phrases. Acoustic analyses were conducted. A total of 66 Belgian-French listeners transcribed the children's utterances orthographically and rated their ease of understanding on a visual analogue scale at sentence and word levels.Outcomes & Results: Acoustic analyses revealed significantly longer duration in response to the big mouth cue at sentence level and in response to both the big mouth and strong voice cues at word level. Significantly higher vocal sound-pressure levels were found following both cues at sentence and word levels. Both cues elicited significantly higher first-formant vowel frequencies and listeners' greater ease-of-understanding ratings at word level. Increases in the percentage of words transcribed correctly and in sentence ease-of-understanding ratings, however, did not reach statistical significance. Considerable variability between children was observed. Conclusions & Implications: Speech cues targeting greater articulatory excursion and vocal intensity yield significant acoustic changes in French-speaking children with dysarthria. However, the changes may only aid listeners' ease of understanding at word level. The significant findings and great inter-speaker variability are generally consistent with studies on English-speaking children with dysarthria, although changes appear more constrained in ...

“…The Swedish speaking SLP could, without knowledge of the Arabic language, perceptually perceive some common speech features characteristics of different dysarthria types such as in ALS, Parkinson's disease and MS. See Supplementary Table S1 for more details. Many features of motor speech production are universal across languages [22] and could, to some degree, explain the Swedish speaking SLP's ability to capture some deviant features in the participants' speech. On the other hand, studies investigating what specific features in a language that may be affected differently in different type of dysarthria across languages are lacking [22].…”

“…In most cases, clinicians do not speak the language of the patient with a different native language. Several aspects of speech production, such as prosody, articulation and dialects are language-specific and may impact intelligibility [14,21,22]. Those aspects are also affected when the speaker uses another language than their native language.…”

Purpose: It is increasingly more common for Speech and Language Pathologists in Sweden to encounter individuals with dysarthria who speak a different language. The aim of the present pilot study was to develop and test a systematic method to be used in collaboration with an interpreter, for assessment of acquired dysarthria in people speaking a language not familiar to the Speech and Language Pathologist. Methods: Seven participants, speaking standard Arabic, were assessed by a Swedish speaking Speech and Language Pathologist using this method and with help of a certified interpreter. The participants were also assessed with equivalent test items from the Swedish "Dysarthria assessment," with instructions translated to Arabic, by a Speech and Language Pathologist speaking standard Arabic and the results were compared. Results: There were no significant differences between the assessments by the Swedish speaking Speech and Language Pathologist and the Arabic speaking Speech and Language Pathologist in the domains "Respiration and phonation," "Articulation," "Listener Comprehension" and "Severity of dysarthria." There was a significant difference between assessments in the domain "Oromotor and velopharyngeal function." Intra-and inter-rater reliability was also calculated using Intraclass Correlation Coefficient and their 95% Confidence Interval. Intra-rater reliability was excellent and inter-rater reliability was very good. Conclusion: The study indicates that a Speech and Language Pathologist, with help of an interpreter, can carry out an assessment of dysarthria in a language unknown to the Speech and Language Pathologist with results comparable to results from an assessment carried out by a Speech and Language Pathologist who speaks the foreign language.

“…Language-specific constraints of treatment still remain largely unexplored, but differences in articulation and prosody across languages are likely to render differential effects of treatment in PD. 83 We maintain that it is of utmost clinical importance for further research to address questions of whether any speech treatment benefits in individuals with PD might be 1) universal, regardless of their language background or 2) constrained by language-specific characteristics.…”

Dysarthria is a motor speech disorder of neurological origin and is characterized by deficits in the execution of movement for speech. Close to 90% of individuals with Parkinson's disease (PD) present with hypokinetic dysarthria, as evidenced by reduced vocal loudness, monotone, reduced fundamental frequency range, consonant and vowel imprecision, breathiness and irregular pauses. The presence of these speech deficits negatively impacts intelligibility, functional communication and, ultimately, social participation. The aims of this review are to 1) describe the nature of this motor speech disorder and its impact on the ability to communicate effectively, 2) provide an overview of medical approaches to dysarthria management and 3) review research on behavioral treatment techniques aimed at improving the intelligibility and quality of life of individuals with dysarthria secondary to PD. The delivery of speech treatment through telepractice is also examined, as this is a modality particularly well-suited to individuals with the mobility difficulties characteristic of PD. Finally, dysarthria management across languages is considered, representing a relevant new and under-researched area in motor speech disorders.
