Abstract:
Purpose The purpose of this research note is to provide a performance comparison of available algorithms for the automated evaluation of oral diadochokinesis using speech samples from patients with amyotrophic lateral sclerosis (ALS). Method Four different algorithms based on a wide range of signal processing approaches were tested on a sequential motion rate /pa/-/ta/-/ka/ syllable repetition paradigm collected from 18 patients with ALS and 18 age- and gender-matched healthy controls (HCs). Results The best temporal detection of syllable position for a 10-ms tolerance value was achieved for ALS patients using a traditional signal processing approach based on a combination of filtering in the spectrogram, Bayesian detection, and polynomial thresholding with an accuracy rate of 74.4%, and for HCs using a deep learning approach with an accuracy rate of 87.6%. Compared to HCs, a slow diadochokinetic rate ( p < .001) and diadochokinetic irregularity ( p < .01) were detected in ALS patients. Conclusions The approaches using deep learning or multiple-step combinations of advanced signal processing methods provided a more robust solution to the estimation of oral DDK variables than did simpler approaches based on the rough segmentation of the signal envelope. The automated acoustic assessment of oral diadochokinesis shows excellent potential for monitoring bulbar disease progression in individuals with ALS.

Abstract:
Objective. Laryngeal diadochokinetic (L-DDK) rate is a measure of laryngeal neural integrity. The objectives for this study included the following: (1) establish the first comprehensive pediatric normative database for L-DDK rates (DDK) using the Voice Evaluation Suite, a computerized voice analysis program; and (2) analyze normal L-DDK rates for age and gender differences. Study Design. Cross-sectional study with planned data collection. Setting. Outpatient pediatric otolaryngology clinic. Subjects and Methods. Three hundred seven children aged 4 to 18 with normal voices. L-DDK rates were collected during a 6-month period. Main outcome measures included age, gender, and L-DDK rates. Results. Three hundred seven children (151 girls and 156 boys) were evaluated. There was no statistically significant difference between the overall mean L-DDK rate of boys (2.69 syllables/s) compared to girls (2.55 syllables/s; P > .05). Further analysis of all individual age groups did not reveal any statistical significance between boys and girls. There was a statistically significant difference among children aged 4 to 11 compared to those 12 to 18 years old. Among boys aged 4 to 11, the mean rate was 2.49 syllables per second, whereas among 12- to 18-year-olds, the rate was 2.95 syllables per second ( P < .01). The mean rate was 2.40 syllables per second among girls aged 4 to 11 and 2.74 syllables per second for those aged 12 to 18 ( P < .01). Conclusion. This is the largest normative pediatric L-DDK analysis in the English literature. The findings suggest that neurolaryngeal development approaches adult maturation at the beginning of the teenage years. These data have the potential application for objective measurement of neurolaryngeal coordination in children with neurologic impairment and also in children who have undergone nerve reinnervation procedures.

Abstract:
This study relates over time the changes in voluntary opening and closing of the vocal folds (vocal fold diadochokinesis, or VFDDK) of patients with amyotrophic lateral sclerosis (ALS). The rate, pattern, and periodicity of VFDDK were examined for 12 ALS subjects with bulbar and 14 subjects with nonbulbar signs of the disease. The acoustical data were analyzed with a commercially available computer-based speech analysis system. ALS patients with bulbar and nonbulbar symptoms demonstrate reduced rate and aperiodic VFDDK as the symptomatology of the neuromotor system progresses. Individuals with bulbar signs show a greater change in vocal fold activity than do the nonbulbar group. Discussion of the clinical implications for initial diagnosis and monitoring of changes over time in motor control of laryngeal function is presented.

Abstract:
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.

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.

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.
