TalkBank FluencyBank

FluencyBank is a shared database for the study of fluency development. Participants include typically-developing monolingual and bilingual children, children and adults who stutter (C/AWS) or who clutter (C/AWC), and second language learners.

Access to the research data in FluencyBank is password protected and restricted to members of the FluencyBank consortium group. Data in the Teaching section of the FluencyBank site is open access and does NOT require membership or a password.

Researchers and clinicians studying fluency who are interested in joining the consortium should read the Ground Rules and then send email to with contact information and affiliation.
Please include a brief statement about how you envision using the data in your research. Students interested in using the data should ask their faculty advisors to join as members. We can also be reached by phone at 301-405-4217.
