Acoustic analysis of amyotrophic lateral sclerosis speech

Application of acoustic speech analysis in amyotrophic lateral sclerosis subjects

Towards Automatic Detection of Amyotrophic Lateral Sclerosis from Speech Acoustic and Articulatory Samples

Amyotrophic lateral sclerosis (ALS) is a rapid neurodegenerative disease that affects the speech motor functions of patients, thus causes dysarthria. There is no definite marker for the diagnosis of ALS. Currently, the diagnosis of ALS is primarily based on clinical observations of upper and lower motor neuron damage in the absence of other causes, which is timeconsuming, of high cost, and ofte...

Occurrence of amyotrophic lateral sclerosis among Iran-Iraq war veterans

  Abstract   Background: Amyotrophic lateral sclerosis (ALS) is a progressive neurological   disorder with high mortality and morbidity. Some risk factors have been implicated for   ALS such as exposure to high magnetic fields, and trace elements like selenium, cadmium and lead. Afew studies have been carried out throughout the world to evaluate   the prevalence of ALS among veterans. This stud...

Tongue movements and their acoustic consequences in amyotrophic lateral sclerosis.

OBJECTIVE The relations between acoustic measures and their articulatory bases have rarely been tested in dysarthria but are important for diagnostic and treatment purposes. We tested the association between acoustic measures of F2 range and F2 slope with kinematic measures of tongue movement displacement and speed in individuals with amyotrophic lateral sclerosis (ALS) and healthy controls spe...

Characterization of Speech from Amyotrophic Lateral Sclerosis by Neuromorphic Processing

Amyotrophic Lateral Sclerosis is a severe disease, which dramatically reduces the speech communication skills of patients as disease progresses. The present study is devoted to define accurate and objective estimates to characterize the loss of communication skills, to help clinicians and therapists in monitoring disease progression and in deciding on rehabilitation interventions. The methodolo...
