In this paper, we propseded the Youngwoo keyboard to help the communication disorders experienced by patients with dysarthria. Existing methods for communication by patients with dysarthria include a letter board with consonants and vowels, a mouse using eye tracking, and communication assistance applications. However, there was a delay of more than 5 minutes per sentence, so there were many difficulties in communication. However, unlike the existing method, the proposed method has been improved so that the patient with dysarthria can communicate by completing the sentences with eye movements. In the conclusion and future work of this paper, the educational use value for Yeongwoo keyboard was analyzed, and it was shown that this training can be of great help to families with ALS patients. The proposed keyboard will be able to improve the difficulties of families by facilitating communication of patients with dysarthria.

This study acoustically examines the quality of fricatives produced by ten dysarthric speakers with cerebral palsy. Previous similar studies tend to focus only on sibilants, but to obtain a better understanding of how dysarthria affects fricatives we selected a range of samples with different places of articulation and voicing. The Universal Access (UA) Speech database was used to select thirteen words beginning with one of the English fricatives (/f/, /v/, /s/, /z/, /ʃ/, /ð/). The following four measurements were taken for both dysarthric and healthy speakers: phoneme duration, mean spectral peak, variance and skewness. Results show that even speakers with mild dysarthria have significantly longer fricatives and a lower mean spectral peak than healthy speakers. Furthermore, mean spectral peak and variance showed significant group effects for both healthy and dysarthric speakers. Mean spectral peak and variance was also useful for discriminating several places of articulation for both groups. Lastly, spectral measurements displayed important group differences when taking severity into account. These findings show that in general there is a degradation in the production of fricatives for dysarthric speakers, but difference will depend on the severity of dysarthria along with the type of measurement taken.

1. Objective This case study reports a Taeeumin patient experiencing hand tremor, heat flash, and mild dysarthria who improved with Yeoldahansotang medication. 2. Method The patient's subjective and objective symptoms were observed daily, and the VAS scores for the main symptoms (hand tremor, heat flash, and mild dysarthria) were recorded daily throughout hospitalization period. 3. Result The patient's general conditions improved by the end of hospitalization, and VAS score dropped dramatically from VAS 10, VAS 10, VAS 10 to VAS 0, VAS 0.5, VAS 3 for hand tremor, heat flash, and mild dysarthria, respectively. 4. Conclusion The patient responded well to Yeoldahansotang, one of the main medicaments for the Joyeol (dry-heat) symptomatic pattern, which indicates that Yeoldahansotang can be used to treat the Joyeol symptomatic pattern even when the textbook indications are not evident as long as the Joyeol pathology is recognizable from other symptoms.

The aim of this study was to analyze consonant articulation errors produced by 90 speakers with cerebral palsy (CP). Phonetic transcriptions were made for 37 single-word utterances containing 70 phonemes: 48 initial consonants and 22 final consonants. Errors of substitution, omission, and distortion were analyzed using a confusion matrix paradigm showing the visualization of error patterns. Results showed that substitution errors in initial and final consonants were most frequent, followed by omission and distortion. Consonant omission occurred more frequently on final consonants. In both initial and final consonants, the within-place errors were more prominent than the within-manner errors. The current results suggest that consonant confusion matrices for dysarthric speech may provide useful information for evaluating speech intelligibility and developing automatic speech recognition system of adults with CP associated dysarthria.

Isolated hypoglossal nerve palsy is a rare clinical condition and it causes deviation of the tongue and dysarthria. A 50-year-old female presented with tongue deviation to the left and mild dysarthria. She had no remarkable past medical history except several recent upper respiratory infections. On examination, the other cranial nerves were intact and she had no focal neurological signs. The findings of MRI and MR angiography were normal. Cerebrospinal fluid analysis revealed only mild elevation of protein. We diagnosed her as suffering with idiopathic isolated hypoglossal nerver palsy and we administered steroid therapy. The dysarthria was improved, but the tongue deviation still remained at 50 days after onset. We report here on a rare case of idiopathic isolated hypoglossal nerve palsy.

In the previous studies, some characteristics of flaccid dysarthria patients have been studied mainly in two aspects: their difficulties in articulation and their metrical dysfunction. Therapeutic research on the articulation impediment of the patients have been carried out extensively (Yorkston, 1981). However, their phonetic characteristics have been less well-studied. The aim of this paper is to measure and describe some phonetic differences between the normal speaker group (six speakers) and the flaccid dysarthria patient group (six speakers in three different degreed of severity). Two types of short sentences comprising of subject-object-verb, i.e. declarative and yes-no question sentences, were recorded to investigate some phonetic characteristics of these two groups of speakers. The two groups (normal group vs. patient group) show differences in yes-no question boundary tone (H% vs. HL%), pitch range (wide vs. narrow), duration (short vs. long) and intensity (strong vs. weak) of sentence final verb endings in Korean.

This study aimed at investigating the effects of CPAP therapy on hypernasality in flaccid dysarthria. The subject was a flaccid dysarthric patient with hypernasality. An A-B-A experimental research design was used. The therapy program was conducted 16 sessions. During CPAP therapy, the subjects was required to repeat single-word utterances in the form VNCV. The results showed some improvement in decreasing hypernasality.

Objective: The purpose of this clinical study is to report the effect of Banhahoobak-tang in the case of a 57-year-old woman with multiple cerebral infarction causing dysphagia and dysarthria diagnosed as pseudobulbar palsy. Methods: A patient was treated with Korean medicine, including herbal medication, acupuncture, and language therapy. We focused on the effect of Banhahoobak-tang by evaluating improvements in symptoms by examining times of aspiration and changes in Speech Mechanism Screening Test scores. Results: After three months of Korean medicine treatment and language therapy, there was improvement in the patient's symptoms, including dysphagia and dysarthria. Conclusions: This study suggests that Korean medicine treatment could be effective for improving the symptoms of pseudobulbar palsy in patients. Specifically, herbal medicine (Banhahoobak-tang) could be an effective choice for treating dysphagia.

Objectives : To introduce a rare case of a patient with Progressive Bulbar Palsy (PBP) and suggest the possibility of treatment using electroacupuncture and Korean Medicine. Methods : A 61-year-old man with PBP, complaining of dysarthria, was treated with electroacupuncture and Korean Medicine, from June 16 to July 10, 2015. Improvements in symptoms were measured using the speech mechanism screening test (SMST), measurement of tongue and orbicularis oris motility, and speech handicap index (SHI). Results : The scores of SMST, motility of tongue and orbicularis oris showed a tendency for gradual improvement with 25 days of Korean Medicine Treatment after admission, but conversation was still impossible. In SHI scores, one point increased in the speech domain and one point decreased in the psycho-social domain, and three points increased in the other domain. Conclusion : Electroacupuncture and Korean Medicine Treatment improved dysarthria caused by PBP, but not completely. Korean Medicine Treatment seems effective in the management of accompanying symptoms such as black hairy tongue, dry mouth, and general condition. The symptoms of PBP are similar to those of amyotrophic lateral sclerosis and there is controversy regarding the classification of PBP. The most important aspect of treating a patient with PBP is an early diagnosis and devising appropriate rehabilitation strategies.

Among the various dysarthric subtypes, diagnosis of ataxic dysarthria is rendered when the speech characteristics include imprecise and irregular articulatory breakdowns, marked degree of speech rate impairment, overall monopitch and monoloudness, and respiratory-articulatory incoordination. Traditionally, speech pathologists have relied only upon their ‘ears’ to describe and evaluate the dysarthric speech. A statement of percentage of correct words identified by a listener do not provide so much more than an index of severity. Within the same perceptual dimension, a carefully constructed speech intelligibility test can specify patterns of errors. The patterns can contain a diagnostic value as well as Provide strategies for remediation. The phonetically transcribed texts on single words and a standard passage, 'kail' produced by an ataxic dysarthria are presented in this report, with an emphasis of the articulatory error analysis. Furthermore,, acoustic tools [e.g., spectrography to measure formant transitions, segment durations, consonant spectra, etc.] are utilized to serve as basic measures that objectively document patients' speech intelligibility, Finally, the treatment methods [e.g., spectrography as a visual feedback, gestural reorganization using pacing method, DAF (Delayed Auditory Feedback)] to modify the dysarthric behaviors are presented.
