Bulbar ALS Detection Based on Analysis of Voice Perturbation and Vibrato
On average the lack of biological markers causes a one year diagnostic delay
to detect amyotrophic lateral sclerosis (ALS). To improve the diagnostic
process an automatic voice assessment based on acoustic analysis can be used.
The purpose of this work was to verify the sutability of the sustain vowel
phonation test for automatic detection of patients with ALS. We proposed
enhanced procedure for separation of voice signal into fundamental periods that
requires for calculation of perturbation measurements (such as jitter and
shimmer). Also we proposed method for quantitative assessment of pathological
vibrato manifestations in sustain vowel phonation. The study's experiments show
that using the proposed acoustic analysis methods, the classifier based on
linear discriminant analysis attains 90.7\% accuracy with 86.7\% sensitivity
and 92.2\% specificity.Comment: Proc. of International Conference Signal Processing Algorithms,

People with dysarthria have impaired speech intelligibility, and quality of communication.
The main goals of the research were to determine the characteristics of speech and voice in adults with hypokinetic, spastic, flaccid and ataxic dysarthria by using an acoustic and spectral analysis, and to determine the quality of communication achieved by these individuals by applying a voice handicap self-assessment instrument. The ultimate goal of the research was to determine the characteristics of speech and voice that are predictors of the quality of communication in individuals with various types of dysarthria.
The sample consisted of 129 respondents with dysarthria, 33 of them being with hypokinetic, 36 with spastic and 30 with flaccid and ataxic dysarthria each. The respondents were of both sexes aged 21-94 (Π=66,07).
The following instruments were used in the research: Multi-Dimensional Voice Program (MDVP) analysis to determine the values of acoustic parameters that indicate the variability of voice frequency, the variability of voice intensity, the presence of tremor and noise in the voice, the presence of subharmonics and interruptions in the voice, as well as periods without voice, and to determine the values of the spectral parameters of Π°ll vowels and certain consonants; Balanced text based on which spectral analysis of the speech was performed; βVoice Handicap Indexβ (VHI) scale used to assess the quality of communication in individuals with dysarthria.
The obtained results showed that characteristics of speech and voice in adults with dysarthria significantly deviate from norms and that they differ among the respondents with hypokinetic, flaccid, spastic and ataxic dysarthria. Also, they showed that the quality of communication was impaired in individuals with dysarthria and that there are similarities among respondents with different types of dysarthria in the degree of handicap experienced by different voice disorders. Based on the results, it was determined that values of acoustic and spectral parameters that determine the characteristics of speech and voice in adults with dysarthria are the predictors of the quality of communication and that they differ among subgroups of respondents. Also, it has been shown that sociodemographic characteristics of respondents and the type of dysarthria can be predictors of the quality of communication
