Remote Speech and Swallowing Assessment in ALS

October 3, 2025 updated by: Andrew Geronimo, Milton S. Hershey Medical Center

Home Telemonitoring of Bulbar Function by Acoustic Measurement of Swallowing and Speech Sounds in ALS

The investigators propose a longitudinal home study of ALS patients to measure the severity of speech and swallowing (bulbar) impairment via a smartphone-based, remote speech and swallow assessment (rSSA). The study is designed to assess the feasibility and validity of such a monitoring intervention. Furthermore, it is proposed that regular monitoring of these two bulbar processes may shed light on their co-evolution over the course of ALS.

Study Overview

Detailed Description

Most individuals with ALS experience bulbar function deterioration over the course of the disease which impacts their quality of life significantly. Furthermore, in some patients, bulbar symptoms are an initial presenting symptom of ALS. Identifying these changes, which may be rapid in some individuals, is complicated by the recent acceleration of virtual care delivery.

The investigators propose a longitudinal home study of ALS patients to assess bulbar progression via a smartphone-based, self-administered remote speech and swallow assessment (rSSA). 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.

Study Population

Population 1: Patients with ALS Population 2: Healthy Listeners

Description

Inclusion Criteria:

Patients

  1. At least 18 years of age
  2. Possess a diagnosis of ALS (definite, probable, probable laboratory-supported, or possible by El Escorial criteria [35])
  3. Have symptom onset within the last 3 years
  4. Demonstrate a score of 2 or 3 in either the speech (item #1) or swallowing (item #3) components of the ALSFRS-R at time of enrollment
  5. Demonstrate decline in bulbar function prior to enrollment, measured by a reduction of at least 1 point on either the speech or swallowing components of the ALSFRS-R in the 6 months prior to enrollment. If 6 months of data is not available, an estimate of the change in ALSFRS-R will be calculated from the time of symptom onset.
  6. Have a life expectancy ≥ 6 months as determined by the attending neurologist
  7. Be fluent in written and spoken English
  8. Possess a smartphone capable of running the study application
  9. Follow up in the Penn State Hershey multidisciplinary ALS clinic over next 6 months
  10. Be able to visit the study site for in-person procedures at weeks 0 and 24

Listeners

  1. Between 18 and 40 years of age
  2. Native speakers of American English 2.3. Currently residing within the United States. 3.4. Hearing within normal limits, as defined by self report.

Exclusion Criteria:

Patients

  1. Possess a co-existing neurological or psychiatric illness that, in the opinion of the study team, exclude the subject from participation
  2. Demonstrate clinically significant dementia, as determined by the ALS study neurologist
  3. Possess abnormal speech or swallowing processes due to a condition independent of their ALS diagnosis

Listeners

  1. Have an identified speech, language, learning, or neurological disorders per self-report
  2. Experience communicating with people with motor speech disorders

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
ALS Patients
All ALS patients will be enrolled in this arm, which involves a combination of clinical and home-based assessments of speech and swallowing.
[Patients only] Weekly completion of audio recordings of speech and swallowing performed at home by the subject using the study smartphone application on their personal device.
[Patients only] MBSS is an instrumented evaluation of oropharyngeal swallowing function that is performed using videofluoroscopy.
Other Names:
  • Videofluoroscopic Swallowing Study (VFSS)
[Patients only] The SIT is a standardized test for measuring speech intelligibility.
Listeners
Healthy listeners will be recruited to listen to the audio recordings of patients in the study in order to judge the intelligibility of their speech.
[Listeners only] Listeners will judge the intelligibility of speech recordings made by patients in the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure

Speech Intelligibility Task (SIT) Intelligibility listener scoring
Time Frame: Weeks 0, 12, and 24
Listeners will score the intelligibility of patient SIT recordings
Weeks 0, 12, and 24
ALS Functional Rating Scale - Revised (ALSFRS-R)
Time Frame: Weeks 0, 12, and 24
ALS Specific Assessment of physical function ranging from 0-48, with 48 being normal function.
