Characteristics of articulatory gestures in stuttered speech: A case study using real-time magnetic resonance imaging

•Articulatory behavior during stuttered speech is important but understudied.•Real-time magnetic resonance imaging is a suitable tool for such investigations.•Disfluent consonants show extreme constriction and delayed constriction release.•Consonant-vowel coproduction is still present when the consonant is disfluent.
