About this trial

The goal of this observational study is to learn how speech and breathing change over time in Spanish-speaking individuals with amyotrophic lateral sclerosis (ALS) compared to age- and gender-matched individuals without ALS.

The main questions it aims to answer are:

Can speech and breathing measures collected through a smartphone application serve as reliable digital biomarkers to track bulbar disease decline in Spanish-speaking people with ALS?

How do these measures differ between individuals with ALS and those without ALS?

Researchers will compare Spanish-speaking participants with ALS to age- and gender-matched healthy controls to see if specific speech and breathing features can identify or predict bulbar decline.

Participants will:

Use a Spanish-language smartphone application to record speech and breathing tasks over time.

Complete assessments of speech, breathing, and functional abilities (e.g., ALS Functional Rating Scale).

Provide data that will be compared to caregiver reports and clinical outcomes to validate new digital biomarkers.

Trial groups

35 Participants
are grouped into 2 trial groups
Group A: People diagnosed with ALS
Group B: Age and Gender matched control group

Trial outcomes

Primary outcomes

1

Oral Speaking Rate

Speaking rate (words per minute): a measure of the rate of speech during oral reading.

Time frame
From enrollment to 2-4 years

Secondary outcomes

1

Maximum Phonation Time (Seconds)

The duration of maximum sustained phonation during the production of "ah" as in "father". Participants will take a deep breath and make the sound for as long as possible. Two trials will be recorded each time.

Time frame
Enrollment to 2-4 years of observations
2

Listener Effort

A perceptual rating of the amount of work necessary for a listener to understand speech, rated by an expert speech-language pathologist on a visual analog scale from 0 (easily understood)- 100 (unintelligible even with full effort)

Time frame
Enrollment 2-4 years

Other outcomes

1

Peak Expiratory Cough Flow

The maximum expiratory airflow velocity achieved during voluntary cough following maximum inspiration (L/min).

Time frame
Enrollment to 2-4 years of observations
2

Forced Vital Capacity

The maximum lung volume that a participant can generate. (raw mL)

Time frame
2-4 years
