Full textAbstract:
Background and Purpose: Diadochokinetic skills (DDK) are thought to reflect speech motor competence. However, there is limited information concerning DDK performance in children with speech difficulties (SD) and how it relates to performance on other speech measures. The main purpose of this study was to investigate relationships between DDK accuracy, consistency and rate and measures of speech and oro-motor skill. A related aim was to identify whether there are distinct DDK profiles that map onto proposed subgroups of speech difficulty such as Developmental Verbal Dyspraxia (DVD). Method: Forty children with SD in the age range 4;0-7;11 were assessed on DDK tasks involving a range of stimuli types and lengths, along with a battery of speech and oro-motor assessments. The children’s performance was compared to that of forty age-matched typically-developing (TD) children. Results: The children with SD performed more poorly than the TD group on all three DDK measures. DDK accuracy correlated strongly with accuracy on speech output tasks and on an input task of mispronunciation detection. DDK consistency correlated with consistency on a single-word naming task. No correlation was found between DDK rate and other speech tasks. Furthermore, no relationship was found between DDK performance and oro-motor skills. Six distinct DDK profiles were identified in the group of children with SD but there was no robust evidence that these profiles map onto the subgroups of speech difficulty that have been proposed in the literature. Conclusion and Implications: DDK skills should be assessed and evaluated in the context of performance on other speech tasks. Theoretical implications are discussed and recommendations for clinical practice are made regarding methods for administering DDK tasks. There was little support for DDK being a unique marker of DVD, rather it appeared to be a marker of speech difficulties in general.

Full textAbstract:
Bakgrund: Essentiell tremor (ET) behandlas bland annat med djup hjärnstimulering (DBS). Många patienter drabbas av stimuleringsinducerad dysartri (SID) till följd av behandlingsmetoden, vilket i sin tur kan påverka talförståeligheten. Oral diadochokinesi (DDK) används av kliniker vid utvärdering av dysartri då det pressar det artikulatoriska systemet. Studier har påvisat samband mellan akustiska egenskaper från DDK och naturligt tal. Ett fåtal studier har undersökt sambandet mellan DDK och talförståelighet men i dagsläget saknas studier inom området som bygger på fler än en kvantifiering av DDK.Syfte: Att undersöka om DDK kan predicera nedsatt talförståelighet till följd av DBS hos patienter med ET. Metod: Inspelade DDK-sekvenser av stavelserna [pa], [ta] och [ka] från 36 patienter med ET samlades in och matchades med skattningar av deras talförståelighet. Inspelningarna märktes upp med hjälp av en tränad mjukvara och kontrollerades sedan manuellt. Ett batteri av 45 akustiska parametrar beräknades på samtliga sekvenser. Statistiska beräkningar genomfördes för att undersöka om erhållna mått kunde predicera talförståelighet.Resultat: För prediktion av talförståelighet påvisades [pa] vara mer värdefull än [ta] och [ka]. Högst uppnådda resultat visade att [pa] kunde förklara 23% av variationen i talförståelighet.Slutsatser: Resultatet visar att DDK kan fungera som en relativt god prediktor av nedsatt talförståelighet till följd av DBS hos patienter med ET. Däremot bör man vara försiktig med att tillskriva DDK ett större förtroende gällande dess samband med talförståelighet, eftersom låga resultat erhölls i vissa beräkningar. Vidare forskning bör validera den använda modellen.<br>Tal- och rösteffekter av djup hjärnstimulering hos patienter med essentiell tremor, D.nr: 2014-67-32M.

Full textAbstract:
Bakgrund: Nedbrytningen av neuroner vid Parkinsons sjukdom har visat sig gå långt innan tydliga motoriska symtom uppkommit. Subtila talförändringar kan förekomma långt innan dessa symtom debuterar och drabbade personer kan länge ha kompenserat för detta omedvetet. I dagsläget finns ingen enkel objektiv kvantifiering som kan ligga till grund för identifiering av artikulatorisk nedsättning hos patienter med Parkinsons sjukdom. Oral diadochokinesi (oral-DDK) har använts av kliniker för att bedöma dysartri då det pressar det artikulatoriska systemet. Ingen tidigare forskning har närmare undersökt vad som händer inuti stavelserna i oral-DDK utan fokuserat på andra faktorer. Mål: Att med enkla akustiska mått på vokalduration undersöka om den skiljer sig mellan personer med Parkinsons sjukdom och normaltalare. Metod: Studiens deltagare bestod av 40 personer med Parkinsons sjukdom och 40 normaltalare. Testdeltagarna fick utföra oral-DDK där stavelserna /pa, ta, ka/ upprepades i normalt respektive snabbt tempo. Vokaldurationen mättes ut av tre uppmärkare. Statistiska analyser utfördes för att se om det fanns skillnader i vokalduration mellan talargrupperna. Resultat: Denna studie visade att det fanns en statistiskt signifikant skillnad i vokalduration mellan personer med Parkinsons sjukdom och normaltalare i samtliga stavelser med undantag för /pa/ i normalt tempo. Slutsatser: Oral-DDK skulle kunna medverka som en komponent i ett tidigt diagnostiseringsverktyg för dysartri. Testet är objektivt och kräver ingen fullständig logopedisk träning och kan således användas av flera yrkesgrupper. Vidare forskning behövs för att närmare undersöka om enskilda ljudsegment är påverkade även vid andra neurologiska sjukdomar.

Full textAbstract:
Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has received more attention in recent years as a treatment option for regulating the symptoms of Parkinson's disease. Previous studies of DBS documented consistent improvements in motor function but more variability in speech outcomes. In the present study, six participants diagnosed with idiopathic Parkinson's disease who reported worsened speech with stimulation were recorded performing speech acoustic tasks with the stimulators on, and again with the stimulators off. Improvements were noted for most participants in measurements of formant slopes, long term average spectrum (LTAS) of a sustained vowel, and spirantization with stimulation on. Stimulation negatively affected most participants' vowel space area, verbal fluency, sequential motion rate, and LTAS while reading and describing a picture. Measures of stop gap duration, alternating motion rate, and voice onset time were within normal limits for most participants across both stimulation conditions.

碩士<br>國立臺北護理健康大學<br>聽語障礙科學研究所<br>101<br>Oral diadochokinesis (oral DDK) are commonly assessed in 4-5 year-old normal preschool children and those with speech disorders. Although data on preschoolers’ DDK performance have been reported, most of these studies had methodological problems or only involved in DDK rates. Therefore, this study aimed to investigate the rate, fluency, accuracy and consistency of oral DDK productions in 4-5 year-old typically developing preschool children in Taiwan.
Sixty-three boys and 63 girls, aged 4-5, with normal developing have been recruited as participants. They have been grouped in 4 age groups: 4 year-old, 4.5 year-old, 5 year-old, and 5.5 year-old. Data on oral DDK productions of /pa/, /ta/, /ka/, /pata/, /taka/and /pataka/ have been collected. Praat, a software for acoustic analysis, has been used to record the oral DDK productions. The rate, accuracy, consistency and fluency of all syllabic repetition were analyzed through software SPSS 19.0.
Results indicated that there were no gender differences in the rate, fluency, accuracy and consistency of oral DDK productions. However, both the DDK rates of monosyllabic and bisyllabic repetitions, and the fluency of /ka/ repetition changed significantly with age. Although the excepted correlations were found among the rate, fluency, accuracy and consistency of oral DDK productions, the relationships were weak. It has showed that the accuracy, consistency and fluency of DDK production and the AMRs were not good predictors for oral DDK rate and the SMRs.
In conclusion, it has been found that 4-5 year-old typically developing Taiwanese preschoolers' oral DDK performances in this study. These findings provided scientific evidence in the clinical evaluation of childhood speech disorders.

碩士<br>國立高雄師範大學<br>聽力學與語言治療研究所<br>97<br>The main purpose of this study is to investigate diadochokinetic (DDK) characteristics of child, adult and geriatric speakers, and to understand: (1) DDK rates and spontaneous speaking rates of the three groups; (2) the effects of speaker’s group and test materials on the typical DDK rates (the fastest rate); and (3) the effects of speaker’s group, speech rates and isochronous units (vowel onset unit vs. whole syllable unit) on speech timing isochrony of DDK utterances. Each group contained thirty participants. Monosyllabic, bisyllablic and trisyllablic utterances are repeated at three different rates (fast, habitual and slow). The pairwise variability index (PVI) was computed to evaluate speech timing isochrony of DDK utterances.
The results show that the typical DDK rates of the child and the adult groups are consistent with the findings of previous studies, but the rate of the geriatric group is much slower. The typical DDK rate and the speech rate of the adult group are significantly faster than those of the child and the geriatric groups, and the speech rate of the geriatric group is significantly faster than that of the child group. There is no significant difference between the child and the geriatric groups on the typical DDK rates. The typical DDK rate is influenced by syllable number, the place of consonant articulation, syllable structure, syllable articulatory sequence and the literal meaning of the test materials. Moreover, DDK timing isochrony is influenced by isochronous units and speaking rates. The PVI of the geriatric group is much greater than those of the child and the adult groups, which implies the speech timing of the geriatric speaker is not as good as those of the child and the adult speakers.

Full textAbstract:
碩士<br>國立高雄師範大學<br>特殊教育學系<br>105<br>The aim of this study was to describe the performance of oral diadochokinesis (oral-DDK) and spontaneous speech rate in preschool children. It was to establish the norms of oral-DDK rate and spontaneous speech rate for preschool children, and to investigate the possible effect of age, the nature of the stimuli presented and different rates (the fastest and habitual rate) on oral-DDK task, and to explore speech errors during the tasks, and to understand the relationship between oral-DDK and spontaneous speech rates. Participants included 90 children lived in Tainan and Kaohsiung , and being elicited in three age groups (4, 5 and 6 years), the numbers of boys and girls are fifty and fifty, asking to repeat monosyllabic, bisyllabic and trisyllabic utterances and describing the story of the Tortoise and the Hare.
The results showed that the development progression was found in both the fastest and habitual oral-DDK rate, the fastest oral-DDK rate in 4-year-old was significantly faster than 5-year-old, but there was no significant difference between 5 and 6-yearold, while the habitual oral-DDK rate did not show significant difference between ages of 4 and 5, and 5 and 6 years. The fastest oral-DDK rate was significantly influenced by the nature of the stimuli presented, including the number of syllables, the placement of consonants, the structure of syllables, and the meaning utterances. In addition, the performance of speech errors during oral-DDK tasks was no significant change with age, but speech errors show the difference in rate, syllable numbers, syllable structures, and meaning utterances. Moreover, spontaneous speech rate also showed that increased with age. Spontaneous speech rate in 4-year-old was significantly slower than 6-yearold, but there was no significant difference between the adjacent age groups. Furthermore, spontaneous speech rate was significant moderately related to the fastest oral-DDK rate, and there is weakly related to the habitual oral-DDK rate. Therefore the findings showed a certain degree of relationship between oral-DDK and spontaneous speech rate.

Full textAbstract:
碩士<br>國立成功大學<br>外國語文學系<br>102<br>With populations aging all over the world, Parkinson’s disease has become a noticeable health problem, and is expected to increase in the future. Parkinson’s disease (PD), termed as idiopathic parkinsonism, is a neurodegenerative disorder which mainly results from loss of dopaminergic neurons (Lang ＆ Lozano, 1998a; Widnell, 2005; Li, Li, ＆ Wang, 2009; Olanow, Stern, ＆ Sethi, 2009; Patel et al., 2009). An estimated 70% of PD patients have speech or voice problems, characterized as hypokinetic dysarthria (Hartelius ＆ Svensson, 1994; Goberman, Coelho, ＆ Robb, 2002). Although previous studies have investigated the speech performances of PD patients, main of them focus only on voice quality in terms of several voice parameters and speaking rate by reading fixed passage. As a consequence, the goal of this present study is to assess speech deficits found in PD patients with dysarthria and investigates the correlation between speech deficits and disease severity, in terms of levodopa equivalent daily dose. This will be accomplished by focusing on six measures: (1) voice quality, (2) maximum sound prolongation (MSP), (3) S/Z ratio, (4) diadochokinetic (DDK) syllable rate, (5) speech intelligibility, and (6) speech rate. 16 male patients diagnosed with PD with Hoehn ＆ Yahr Stage ratings of 2 to 4 were recruited from a hospital in Southern Taiwan. 16 control subjects, matched with age, sex and native language with the PD patients, also participated in this study. The present study has collected data by taking sound recordings of participants performing four oral tasks.
Three major findings have been made: (1) PD patients tend to have speech deficits in the areas of MSP, DDK rate, speech intelligibility, and speech rate. PD patients are relatively unable to sustain certain sounds and have poor performance on oral cyclic movement. In addition, PD patients are less intelligible and speak much slower than controls in a variety of speech contexts. (2) When different speech contexts are compared, relatively low speech intelligibility in spontaneous monologue occurs, which may be due to the lack of the provision of external cues in conversation. (3) Disease severity, in terms of levodopa equivalent daily dose, is found to statistically correlate with speech rate of answering questions. Patients with more severe PD speak slower when people elicit new information from them, than those with less severe PD.
These findings will help us to have a clearer understanding of the communication problems of patients with Parkinson’s disease, and it is hoped that this improved understanding will lead to more successful communication of PD sufferers with their family and caregivers.
