Description of the task. ( A ) Overview of the task: MRI session composed of 4 functional runs divided in trials separated by an inter-trial-interval of 16 s. In each trial, participants produced a given item 3 times. Items are disyllabic non-words (e.g.., bәbә). ( B ) Stimuli and laryngeal control: stimuli was balanced for place of articulation (bilabial and alveolar) and manner of articulation (orals and nasals), and the controlled vowel schwa (ә); for the voiced condition, the IA (interarytenoid) and LCA (lateral cricoarytenoid) laryngeal muscles are recruited, whereas the PCA (posterior cricoarytenoid) is not, and the reversed for the whispered condition. ( C ) Detail of task for a given trial: 0.9 s of silent gap were introduced between consecutive TRs for speech production without MRI noise; top: sound recording in black and low-pass-filtered signal envelope in red; below-left: spectrogram image of an utterance example; below-right: scatter plot <t>of</t> <t>F1</t> and <t>F2</t> formants in a given participant (each dot represents an utterance), red for voiced and blue for whispered speech.
