Myasthenia Gravis Connected Speech Acoustic Metrics and Clinical Scores

Seventeen patients with myasthenia gravis participated in a cross-sectional study, providing voice recordings and clinical assessments. The dataset includes acoustic metrics like root-mean-square intensity and fundamental frequency from tasks such as sustained vowels, reading, and spontaneous speech. It was authored by Aurora Zanghì and last updated on 2026-05-19.

Use Cases

• Identify acoustic markers of bulbar dysfunction based on intensity and fundamental frequency measurements.
• Investigate sex-related differences in speech patterns based on the described intensity reductions in male participants.
• Correlate patient-reported outcomes like MG-ADL and rMG-QOL15 with objective acoustic metrics.
• Explore task-dependent speech alterations based on data from sustained vowels, reading, and spontaneous speech tasks.

Strengths

• Includes data from 17 patients with confirmed myasthenia gravis.
• Contains contemporaneous clinical assessments (MG-ADL, rMG-QOL15) paired with acoustic recordings.
• Acoustic metrics are specified, including root-mean-square intensity (dB) and fundamental frequency (Hz).
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 26.1 KB, indicating a limited scope and sample size.
