Use of Electropalatography to Improve Speech Sound Production

2019-08-16 19:05:30 | BioPortfolio


The purpose of this proposed study is to examine the benefits of using electropalatography (EPG) during speech therapy with adult individuals who are either congenitally deaf or adventitiously deaf and use a cochlear implant.


It has been established in numerous research studies that there is a definitive link between speech perception and speech production, in that what one can perceive, one can produce. Hearing loss disrupts this link and while cochlear implants make a significant difference in perception of sound, adults who are deaf and receive a cochlear implant (CI) do not gain the same perceptual benefits as children who are deaf and are implanted at a young age. Thus, the speech production of the adult CI user is reported to be less intelligible. The purpose of this proposed study is to examine the benefits of using electropalatography (EPG) during speech therapy with adult individuals who are either congenitally deaf or adventitiously deaf and use a cochlear implant. The investigators have proposed to study 10 CI users (5 in each etiological group) who will undergo speech intelligibility testing, and receive speech therapy (1x/week for 10 weeks) using EPG that provides both visual (biofeedback) and auditory feedback. It is hypothesized that the biofeedback in addition to the auditory feedback from the CI will result in an increase in articulation skills and thus the speech intelligibility in these individuals will improve significantly.

Medical and Biotech [MESH] Definitions

The therapy technique of providing the status of one's own AUTONOMIC NERVOUS SYSTEM function (e.g., skin temperature, heartbeats, brain waves) as visual or auditory feedback in order to self-control related conditions (e.g., hypertension, migraine headaches).

Professionals skilled at diagnostic testing of hearing, HEARING IMPAIRMENT, and CORRECTION OF HEARING IMPAIRMENT by non-medical or non-surgical means.

Disorders of hearing or auditory perception due to pathological processes of the AUDITORY PATHWAYS in the CENTRAL NERVOUS SYSTEM. These include CENTRAL HEARING LOSS and AUDITORY PERCEPTUAL DISORDERS.

Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.

Procedures for correcting HEARING DISORDERS.
