Motor Speech Disorders : A Cross-Language Perspective
No full textMotor speech disorders are a common accompaniment of a whole range of neurological conditions, from stroke, brain injury and Parkinson’s disease through to many rarer conditions. This book aims to aid understanding of the nature of motor speech disorders from a cross-language perspective, in contrast to the largely English-centric nature of research and practice recommendations to date. The book looks not just at how these motor speech disorders are assessed and treated in other countries, but also examines how underlying speech impairments differ according to the language someone speaks. The book studies the underlying neurological, neurophysiological and neurophonetic characteristics of motor speech disorders in different language contexts, and discusses the implications these have for clinical rehabilitation. This significantly adds to debates around the theoretical understanding and clinical management of motor speech disorders
Motor speech disorders in Chinese
Full text linkChinese, spoken by approximately 20% of the world’s population, is the most commonly spoken language in the world (Fung, 1990). There is some debate regarding whether varieties of spoken Chinese should be considered dialects or separate language. Here, we regard them as separate languages. The various languages of Chinese are considered united by a common written system, although this characterization is problematic for Cantonese, which has many colloquial expressions with no written form (Bauer & Benedict, 1997). In this chapter, we focus on two of the most common Chinese languages, Cantonese and Mandarin (Putonghua). Cantonese is spoken in Hong Kong, Southern China and many overseas Chinese communities. Mandarin, also known as Standard Chinese, is the official national language of China and Taiwan, and is one of the four official languages of Singapore.caslpub3214pu
Temporal and spatial variability in speakers with Parkinson's Disease and Friedreich's Ataxia
No full textSpeech variability in groups of speakers with Parkinson's disease (PD) and with Friedreich's ataxia was compared with healthy controls. Speakers repeated the same phrase 20 times at one of two rates (fast or habitual). A non-linear analysis of variability was performed which used some of the principles behind the spatio-temporal index (STI). The STI usually employs variation in lip displacement over repetitions of the same utterance and a linear analysis of such signals is conducted to represent the combined variation in spatial and temporal control. When working with patients, audio measures (here we used speech energy) are preferred over kinematics ones as they are minimally disruptive to speech. Non-linear methods allow spatial variability to be estimated separately from temporal variability. The results are tentatively interpreted as showing that PD speakers were distinguished from healthy control speakers in spatial variability and ataxic speakers were distinguished from controls in temporal variability. These findings are consistent with the speech symptoms reported for these disorders. We conclude that the non-linear analysis using the speech energy measure is worth investigating further as it is potentially revealing of the differences underlying these two pathologies
Diagnosis and Therapy in Adult Acquired Dysarthria and Apraxia of Speech in Dutch:Motor Speech Disorders. A Cross-Language Perspective

Full text linkCognition and its assessment in motor speech disorders
No full textMotor speech disorder (MSD) rarely occurs as an isolated sequel to or sign of neurological damage. The causative injury in dysarthria and apraxia of speech commonly results in a variety of impairments, and resultant limitations in activity and participation, relating to physical, sensory, psychological and cognitive domains. These impairments may negatively impact on individual presentation, prognosis for maximization of communication status, and speech management. For a high proportion of the MSD population, ability and performance are further compromised by natural aging or concomitant diseases, including dementia. Surgical and pharmaceutical interventions and the potential of the latter to interact with neuropathology may also affect individual status. The focus of this chapter is the cognitive status of the person with MSD, with reference to some common pathologies, and its relevance to motor speech assessment. Cognitive assessment is also considered, with particular attention to published tools which may inform the speech-language pathologist (SLP), about the cognitive status of the individual with MSD
