Articulatory Effort and Speech Adaptation Data from French Speakers

Experimental data from a study on how physical effort influences speech adaptation to auditory perturbations. The dataset includes acoustic (formant frequencies) and physiological (EMG) measurements from 21 native French speakers performing a speech task under two effort conditions. The data was published by Elodie Ronayette on figshare under a CC-BY-4.0 license in May 2026.

Use Cases

• Modeling the relationship between motor effort and compensation magnitude based on perturbation levels.
• Analyzing the saturation point of speech adaptation based on acoustic F2 and EMG activity data.
• Investigating articulatory strategy shifts (e.g., from lip rounding to tongue backing) under high perturbation levels.
• Studying individual variability in sensorimotor adaptation within a controlled phonetic context (/ne/–/nø/).

Strengths

• Includes data from 21 participants, providing a basis for analyzing individual variability.
• Contains synchronized acoustic (F1, F2) and physiological (orbicularis oris EMG) measurements.
• Experimental design includes two distinct articulatory effort conditions (FLT and RLT) for comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (5.8 MB), which may indicate limited scope or aggregated summary statistics.
