Stuttering is a complex speech disorder that negatively affects an
individual's ability to communicate effectively. Persons who stutter (PWS)
often suffer considerably under the condition and seek help through therapy.
Fluency shaping is a therapy approach where PWSs learn to modify their speech
to help them to overcome their stutter. Mastering such speech techniques takes
time and practice, even after therapy. Shortly after therapy, success is
evaluated highly, but relapse rates are high. To be able to monitor speech
behavior over a long time, the ability to detect stuttering events and
modifications in speech could help PWSs and speech pathologists to track the
level of fluency. Monitoring could create the ability to intervene early by
detecting lapses in fluency. To the best of our knowledge, no public dataset is
available that contains speech from people who underwent stuttering therapy
that changed the style of speaking. This work introduces the Kassel State of
Fluency (KSoF), a therapy-based dataset containing over 5500 clips of PWSs. The
clips were labeled with six stuttering-related event types: blocks,
prolongations, sound repetitions, word repetitions, interjections, and -
specific to therapy - speech modifications. The audio was recorded during
therapy sessions at the Institut der Kasseler Stottertherapie. The data will be
made available for research purposes upon request.

本论文介绍了基于治疗的数据集 Kassel State of Fluency (KSoF)，其中包含了超过 5500 个人的口吃治疗过程语音记录。这些记录标注了六种与口吃相关的事件类型，可用于研究监测和干预早期复发的可能性。
