Background: Delayed auditory feedback (DAF) has been used in the treatment of stuttering, providing different results across different populations and age groups. Aims: This study examines the impact of delayed auditory feedback (DAF) on stuttering-like disfluencies (SLDs) in the spontaneous speech of Jordanian individuals who stutter. Methods & Procedures: A cross-sectional experimental design was employed to analyse the effects of DAF on the conversational speech of 35 participants (9 females, 26 males) with persistent developmental stuttering, aged 5--29 years (M = 13.1, SD = 6.1). The Stuttering Severity Instrument was used to assess the severity of stuttering. Participants who met the inclusion criteria were asked to talk about general topics of their interests during two different listening conditions (with DAF and without DAF). Outcomes & Results: No significant DAF effects were found on SLDs in terms of duration [p = 0.18] (blocks, prolongations) and repetition [p = 0.22] (sound repetition, syllable repetition, word repetition). Neither severity nor age affected the use of DAF on SLDs. Conclusions & Implications: The study concludes that DAF did not result in a significant decrease in SLDs in the spontaneous speech of participants. These findings highlight the limited effect of DAF in reducing stuttering in this specific population.
