Kassel State of Fluency - Challenge

The stuttering Kassel State of Fluency corpus KSoF-C, provided is derived from the Kassel State of Fluency (KSoF) corpus. The original corpus fea- tures some 5500 typical and nontypical (stuttering) 3-sec segments from 37 German speakers with an overall duration of 4,6 hours. The segments contain speech of persons who stutter (PWO). The record- ings from which the segments were extracted were recorded before, during, and after PWOs underwent stuttering therapy. KSOF-C only features the 4601 non-ambiguously labeled segments. The task proposed in this challenge is the classification of speech segments as one of the 8 classes - the seven stuttering-related classes mentioned above and an eighth “garbage” class, denoting unintelligible segments, segments containing no speech, or segments that are negatively affected by loud background noise. The dataset is split by speaker (train, 23 spk, devel, 6 spk, test, 8 spk
