F2 Transition Measurement in Bulgarian Adults who Stutter and who do not Stutter
There is strong research evidence that F2 transitions may be used to differentiate the speech of persons who stutter from that of persons who do not stutter. However, what is known about F2 transitions in stuttering is based mostly on speakers of English. In this paper we present the first experiment on F2 transition in native Bulgarian speakers. Subjects included four Bulgarian adult males who stutter (mean age = 24 years) and four age-matched Bulgarian adult males who do not stutter. The software product Motor Speech Profile (MSP) as a part of the computerized speech laboratory (Kay Pentax) was used for the measurement of F2 transition. There was a notable difference in the magnitude of F2 variations, the rate of F2 variations and the regularity of F2 variations between participants who stutter and who do not stutter.
