RITTO, Ana Paula; JUSTE, Fabiola Staróbole  e  ANDRADE, Claudia Regina Furquim de. The effect of the SpeechEasy® device on acoustic and speech motor parameters of adults who stutter. Audiol., Commun. Res. [online]. 2015, vol.20, n.1, pp.1-9. ISSN 2317-6431.  http://dx.doi.org/10.1590/S2317-64312015000100001440.

Purpose

To investigate variations in speech motor skills in adults who stutter and those who do not, using the SpeechEasy® altered auditory feedback device.

Methods

1 2

Results

The spontaneous speech task was the only task to show significant differences in both the intragroup and intergroup comparisons. In this task, the use of SpeechEasy® resulted in significant improvement in speech fluency, as measured by the percentage of stuttered syllables, for the group who stuttered. For the fluent group, the device produced the opposite effect: a significant increase in the frequency of stuttered disfluencies was observed with the device. No significant differences were found in either intragroup or intergroup comparisons relating to the acoustic aspects of the diadochokinesis and target phrase production tasks.

Conclusion

The results indicated that the use of SpeechEasy® improved the fluency of participants who stutter, without appearing to interfere with speech naturalness.
