It has been reported previously that presentation of an altered form of the voice enhances the fluency of people who stutter. One of these forms of alteration is frequency-shifted feedback. The effects of frequency-shifted feedback were compared between two speaker groups that differed in age. The fluency-enhancing effects of frequency-shifted feedback was greater for adult speakers (mean age 21.3) than for children (mean age 9.11). The results are discussed in terms of their implications for theory and treatment.
