“…Similar findings related to increased jitter were reported by Silbergleit et al [24], who performed acoustic analysis of voice in 20 patients. Each patient phonated the /a/ vowel for 3 s at comfortable, high, and low pitches (three times each).…”

“…Our study also revealed a decrease in F₀ values. Silbergleit et al [24] came to the same conclusion after acoustic analysis of voice in ALS patients with apparently unchanged voice; in these patients the abnormalities of F₀ were detected before the appearance of clinical bulbar symptoms.…”

“…shimmer, mean F₀, and NHR was presented in all of the previously mentioned reports [14,21,23,24,25]. Robert et al [23] examined mean shimmer value and found its increase particularly among patients with bulbar ALS.…”

“…Acoustic voice analysis was introduced as a means for more objective description of voice disturbances among patients with ALS, and has been utilized and described by several authors [14,21,23,24,25]. Our study utilized the four most important and commonly used parameters, and were measured both in men and women.…”

Objective: Voice abnormalities are among the symptoms occurring in patients with amyotrophic lateral sclerosis (ALS). They are divergent and range from hoarseness, through the excessive adduction of false folds, up to the weakness of the vocal folds. The aim of the study was to analyze the phonatory function of the larynx in ALS patients. Methods: Seventeen patients with ALS were evaluated with subjective perceptual voice assessment (including the GRBAS scale), videolaryngostroboscopy including voice range and maximum phonation time (MPT), and objective acoustic voice analysis with IRIS software (including evaluation of jitter, shimmer, mean fundamental frequency, and noise-to-harmonics ratio (NHR)). Examinations were performed three times at 6-month intervals. Results: Hoarseness, roughness, and breathiness of voice were all found more frequently in the majority of these patients. Voice range, amplitude of vibration, mucosal wave, and glottal closure showed significant abnormalities with repeated examinations. MPT was shortened especially among women with ALS. Acoustic analysis of voice among men showed increased jitter value in the first examination only, while jitter, shimmer, and NHR in women with ALS were increased in all examinations. Conclusions: Analysis of voice qualities among patients with ALS allows for the detection of various abnormalities associated with the natural progression of the disease.

“…Beukelman et al (2011), Duffy (2013, Green et al (2013), and Orimaye et al (2014) have established that pronunciation varies systematically within categories of speech impairment. (Silbergleit et al, 1997;Carrow et al, 1974) have shown that ALS speech shows deviant characteristics. For example, (Ball et al, 2001) observe that ALS speakers manifest altered voice quality.…”

Approximately 80% to 95% of patients with Amyotrophic Lateral Sclerosis (ALS) eventually develop speech impairments (Beukelman et al., 2011), such as defective articulation, slow laborious speech and hypernasality (Duffy, 2013). The relationship between impaired speech and asymptomatic speech may be seen as a divergence from a baseline. This relationship can be characterized in terms of measurable combinations of phonological characteristics that are indicative of the degree to which the two diverge. We demonstrate that divergence measurements based on phonological characteristics of speech correlate with physiological assessments of ALS. Speech-based assessments offer benefits over commonly-used physiological assessments in that they are inexpensive, non-intrusive, and do not require trained clinical personnel for administering and interpreting the results.

e describe 4 patients with amyotrophic lateral sclerosis (ALS) and glottic narrowing due to vocal cord dysfunction, and review the literature found using the following search terms: amyotrophic lateral sclerosis, motor neuron disease, stridor, laryngospasm, vocal cord abductor paresis, and hoarseness. Neurological literature rarely reports vocal cord dysfunction in ALS, in contrast to otolaryngology literature (4%-30% of patients with ALS). Both infranuclear and supranuclear mechanisms may play a role. Vocal cord dysfunction can occur at any stage of disease and may account for sudden death in ALS. Treatment of severe cases includes acute airway management and tracheotomy.
