BACKGROUND Persons with stuttering (PWS) often present with other co-occurring conditions. The World Health Organization's (WHO) International Classification of Functioning, Disability and Health (ICF) proposes that it is important to understand the full burden of a health condition. A few studies have explored voice problems among PWS, and the characteristics of voices of PWS are relatively un...
