Purpose: To investigate the impact on percentage of syllables stuttered of various
durations of delayed auditory feedback (DAF), levels of frequency-altered feedback
( FAF), and masking auditory feedback (MAF) during conversational speech.
Method: Eleven adults who stuttered produced 10-min conversational speech samples
during a control condition and under 4 different combinations of DAF, FAF, and MAF.
Participants also read aloud in a control condition with DAF and FAF.
Results: A statistically significant difference was found between the NAF conversation
condition and the 4 combined altered auditory feedback (AAF) conditions. No
statistically significant differences in percentage of syllables stuttered were found in
conversation or reading between the control conditions and the FAF/DAF or MAF
conditions. The analysis of individual participants’ data showed highly individual
responsiveness to different conditions.
Conclusions:
Participants’ varying responses to differing AAF settings likely accounted
for the failure to find group differences between conditions. These results suggest
that studies that use standard DAF and FAF settings for all participants are likely to
underestimate any AAF effect. It is not yet possible to predict who will benefit from
AAF devices in everyday situations and the extent of those benefits.
