Ahmed Rivera-Campos, Ph.D. – Research

Line of Research

The overall objective of Dr. Rivera Campos’ research interest is the use of biofeedback technologies for speech sound production.  From this broad view, three distinct branches of research are borne.

  1. Clinical and translational research in the remediation of residual speech sound errors in children, speech errors due to hearing loss and errors due to foreign language learning.  Studies that are currently being done in this area include:
    • Studying the efficacy of ultrasound imaging biofeedback for remediation of English /r/ errors
    • Studying the effectiveness of ultrasound imaging for teaching production of trilled /r/ to individuals learning Spanish as a foreign language.
    • Studying the effectiveness of electropalatography biofeedback for the remediation of English /r/ errors.
  2. Research aimed at better understanding the articulatory requirements of sounds that are commonly considered challenging to master production (for example, the Spanish trill /r/)
  3. Training of clinicians and other professionals in the use of biofeedback technologies for remediation of speech errors and for foreign language instruction in sound production. A study currently being done in this area include:
    • Studying training efficacy in ultrasound imaging for remediation of speech sound errors in clinicians.
