Linguistic factors and stuttering in Nepali speaking adults who stutter

ABSTRACT

This study aimed to determine the effect of phonological and morphological factors on the dysfluencies of Nepali-speaking adults who stutter. Eighteen Nepali-speaking adult speakers with mild to very severe developmental stuttering were recruited. The spontaneous speech sample was audio-video recorded and transcribed through orthographic transcription. A total of 350 syllables were analysed to calculate stuttering frequency. Phoneme position, phoneme category, and word length were considered as the phonological factors and word-class as morphological factors. The percentage of stuttering for each of these variables was computed. The study’s outcome displayed a significant effect of phoneme position and word length but no effect of phoneme category. Significantly greater stuttering was noticed in the word-initial position and longer words compared to word-medial and shorter words, respectively. In morphological factors, content words and content-function words had a greater stuttering rate than function words. This study showed a significant effect of phoneme position, word length, and grammatical class on the frequency of dysfluency in Nepali-speaking adults who stutter but no effect of phoneme category. The phonetic complexity of these variables may lead to an increase in motor planning demand resulting in more stuttering.
