Speech and facial expression analysis
In a pilot project, Ambulanzpartner is offering digital speech and facial expression analysis via the ALS app. Analyzing speech and facial expressions in ALS is useful as the speech and facial muscles are affected during the course of the disease. The data is of great interest for the treatment of ALS. In the future, the analysis of speech and facial expressions could be used to assess the therapeutic effectiveness of medication and other treatment methods.
How does the speech and facial expression recording via the ALS app work?
Recording speech and facial expressions with the ALS app takes about 5 to 10 minutes per session. The analysis software provides a short, standardized program with questions and answers, voice and reading exercises, and free speech. While speaking, the smartphone’s camera and microphone record the movements of the facial muscles. The program compares the changes in speech and facial expressions between sessions. For each change, an assessment of the impairment’s severity is provided.
Speech and facial expression analysis
The technical method is being established in a pilot project with a small group of ALS patients. Only these users will have access to speech and facial expression recording on the start page of the ALS app.
A special protocol for people with ALS guides you through the program for speech and facial expression recording.
