Auditory Masking Effects on Speech Fluency in Aphasia and Apraxia of Speech

NCT02094014 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 46

Last updated 2016-05-12

No results posted yet for this study

Summary

Impaired speech production is a major obstacle to full participation in life roles by stroke survivors with aphasia and apraxia of speech. The proposed study will demonstrate the short-term effects of auditory masking on speech disfluencies and identify individual factors that predict a positive response, enabling future work to develop auditory masking as a treatment adjuvant targeting long-term improvement in speech. Providing an additional treatment option for adults with aphasia and apraxia of speech will have the clear benefit of improving quality of life and allowing individuals to participate more actively in their health care decisions through improved communication.

Conditions

  • Apraxia of Speech
  • Aphasia
  • Cerebrovascular Accident

Interventions

BEHAVIORAL

Normal Auditory Feedback

Participants will produce sentences under normal speaking conditions, able to hear their own speech.

BEHAVIORAL

Masked Auditory Feedback

Participants will produce sentences while listening to speech-shaped noise at 85 decibels (sound pressure level) to mask ability to hear their own speech.

BEHAVIORAL

Altered Auditory Feedback

Participants will produce sentences while listening to their speech shifted up one octave and delayed.
