Effects of emotion on the acoustic parameters in adults who stutter: An exploratory study

- Fundamental frequency (Fo) did not differ between groups or across emotional conditions.
- Descriptive analysis revealed slower F2 transition durations across tokens and conditions in the AWS.
- AWS showed a larger F2 transition extent when speaking under arousing versus neutral conditions for some of the CVt tokens.
- AWS showed steeper slopes for 7 out of 12 CVt tokens when they performed under emotional conditions.
