Quantitative acoustic metrics of vowel production in mandarin-speakers with post-stroke spastic dysarthria.

Abstract: Impairment of vowel production in dysarthria has been highly valued. This study aimed to explore the vowel production of Mandarin-speakers with post-stroke spastic dysarthria in connected speech an...

Effects of the Types of Noise and Signal-to-Noise Ratios on Speech Intelligibility in Dysarthria

Abstract: This study investigated the effects of the types of noise and signal to noise ratios (SNRs) on speech intelligibility of an adult with dysartrhia. Speech intelligibility was judged by 48 naive listeners using a word transcription task. Repeated measures design was used with the types of noise (multi-talker babble/environmental noise) and SNRs (0, +10 dB, +20 dB) as within-subject factors. The dependent measure was the percentage of correctly transcribed words. Results revealed that two main effects were statistically significant. Listeners performed significantly worse in the multi-talker babble condition than the environmental noise condition, and they performed significantly better at higher levels of SNRs. The current results suggested that the multi-talker babble and lower level of SNRs decreased the speech intelligibility of adults with dysarthria, and speech-language pathologists should consider environmental factors such as the types of noise and SNRs in evaluating speech intelligibility of adults with dysarthria.

8 – Clinical Speech Syndromes of the Motor Systems

Abstract: Damage to the motor system responsible for speech production may occur at any point along the pathway from the cerebrum to the muscle itself Paralysis, weakness, or incoordination of the oral musculature may result in a clinical entity known as dysarthria In the classic study of of dysarthria resulting from certain sites of damage in the neural system, six different types were identified from neuroanatomical and acoustic-perceptual judgments of speech: spastic, flaccid, ataxic, hypokinetic, hyperkinetic, and mixed This chapter describes these dysarthrias according to their neuroanatomical site of dysfunction, associated disease processes, and the effects of these diseases on articulation, resonance, phonation, prosody, and swallowing Further research using perceptual and acoustic analysis has added to knowledge about the speech characteristics associated with diseases, trauma, and injuries to the neuromuscular aspect of the speech mechanism

The Prosody of Typical and Atypical Speech of Buenos Aires Spanish

Abstract: This study examines the prosody of Buenos Aires Spanish in speakers with typical and atypical speech (stuttering, dysarthria, acquired hearing impairment, developmental speech disorder, and dysphonia) in three age groups equally divided for gender (5–8, 18–50, and 51–78). The corpus contained simple declarative sentences, wh-questions, and exclamatory sentences using a repetition task. The data were transcribed using the Autosegmental- Metrical theory (AM) and the ToBI system adapted for Argentine Spanish. The results show an inverse proportion between the difficulty of the sentence and the range of prosodic variation between the typical and atypical speakers: in the simple declarative sentences, the differences were the greatest, followed by the more difficult marked exclamatory sentences, whereas in the most difficult wh-questions the differences appear to be neutralized. The results were explained according to the theory of Phonology as Human Behavior that views language as a compromise in the...

Developing a Technology-Based Speech Intervention for Acquired Dysarthria A Psychological Approach

Abstract: New technology promises high potential for empowerment and training in the health area. Effectiveness of training, however, is based upon realiable and frequent usage of technology. To achieve this goal we propose an approach based upon psychological models of motivation, namely self- determination theory. Using the example of patients with acquired speech motor impairments as dysarthria due to Parkinson's disease, we outline design strategies for tailored and adaptive technology that is embedded in speech therapy and allows for autonomous usage. "ISi-Speech" profits from an inter- disciplinary team of technicians, speech therapists and psychologists who were recently funded by the German ministry of Education and Research to build a digital training system for treatment of dysarthria. End users will be involved into design and formative evaluation processes.
