Home telemonitoring of bulbar function by acoustic measurement of swallowing and speech sounds in ALS
Most individuals with ALS experience changes in speech and swallowing over the course of the disease. In some, these are their initial indication of ALS. Identifying these changes, which may be rapid in some individuals, is complicated by the recent acceleration of virtual care delivery. This is a longitudinal home study of ALS patients to assess speech and swallowing function through use of smartphone application. The overall hypothesis is that this monitoring protocol can be used in a way that, 1) is satisfactory to the patient, 2) performs at least as well as standard clinical measures of dysarthria and dysphagia, and 3) resolves the development of emergence of speech and swallowing pathologies in ALS. Patients enrolling in this study will participate for approximately 24 weeks, during which they will have swallowing and speech tests performed, complete surveys, and perform audio recordings of speech on their cellphone. Healthy controls will be enrolled to judge the intelligibility of speech samples provided by patients in the study.
