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.
- 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.
- Research aimed at better understanding the articulatory requirements of sounds that are commonly considered challenging to master production (for example, the Spanish trill /r/)
- 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.

Student Research and Clinical Experiences at B.E.S.T. Lab
Graduate and undergraduate students from our program have the opportunity to volunteer hours in B.E.S.T. Lab to obtain clinical hours and research experience. For NSSLHA members, the volunteer hours may count for up to 4 points. Students also have the opportunity to conduct research in B.E.S.T. Lab as part of their thesis, Honors project or undergraduate research project.
Current Graduate Research Assistant: Jyl Ristau
Current Undergraduates working in B.E.S.T. Lab: Matilde Patino Arreguin, Victoria Patino Arreguin, and Hannah Feehan
Ahmed Rivera-Campos, Ph.D.
Ahmed Rivera Campos, Ph.D., is a Spanish-English bilingual Speech-Language Pathologist and assistant professor at the Davies School of Communication Sciences and Disorders in the Harris College of Nursing & Health Sciences at TCU. He obtained his Master’s in Speech Language Pathology in Puerto Rico (Universidad del Turabo) before pursuing a doctoral degree in Communication Disorders at the University of Cincinnati. His research, clinical and teaching interests focus on the use of biofeedback technologies such as ultrasound imaging for studying the articulatory requirements of sounds as well as assessment and amelioration of speech errors.
In the Davies School of Communication Sciences and Disorders, Dr. Rivera Campos teaches Phonetics, Speech & Hearing Science, and Evidence-Based Practice in the area of Communication Disorders.
Welcome to the Biofeedback Education for Speech Treatment Lab (B.E.S.T. Lab). Our lab is directed by Dr. Ahmed Rivera Campos to conduct translational clinical research and clinical work. Other faculty members that collaborate in the lab are Lynn Flahive CCC-SLP and Irmgard Payne CCC-SLP. The main purpose of B.E.S.T. Lab is to expand our knowledge in the use of biofeedback technologies for the diagnostic and remediation of speech sound errors. This includes children with residual speech sound errors, speech errors due to hearing loss, and individuals who are learning a foreign language.
B.E.S.T. Lab is housed within the Miller Speech and Hearing Clinic located on the campus of Texas Christian University.
Why are we interested in biofeedback technologies? An advantage of biofeedback technologies such as ultrasound imaging and electropalatography is that it allows clinicians to see in more detail what caused the distortion when a speech sound was produced. It allows clinicians to answer questions like: was the distortion due to inaccurate tongue root positioning or inaccurate tongue-palate contact? By using biofeedback, we can use this information to better guide our patients on how to achieve more accurate speech sound production.
At B.E.S.T. Lab, we use biofeedback technologies such as:
- Ultrasound imaging
