Filter by:With advancing age, adults experience increasing speech understanding difficulties in challenging situations. Currently, speech-in-noise difficulties are rehabilitated by providing hearing aids. For older normal-hearing adults, however, hearing devices do not provide much benefit since these adults do not have decreased hearing sensitivity. The goal of the "Speech Perception and High Cognitive Demand" project is to evaluate the benefit of a new auditory-cognitive training paradigm. In the present study neural (as measured by pupillometry and magnetoencephalography) and behavioral changes of speech-in-noise perception from pretest to posttest will be examined in older adults (age 65 - 85 years) assigned to one of three training groups: 1) Active Control Group: sessions of watching informational videos, 2) Auditory Training Group: sessions of auditory training listening to one of two speakers in everyday scenarios (e.g., driving directions) and needing to recall what one speaker said in the previous sentence, and 3) Auditory-cognitive training group: identical to the auditory training group, except participants will be asked to remember information from two previous sentences. Changes in speech-in-noise perception will be examined for the three groups of older adults and gains will be compared to a control group of young, normal hearing adults (18-30 years) that is not part of the clinical trial and will not undergo any training.
This study will evaluate the ability of MyoVoice to replace natural speech. Referred to generally as an Augmentative and Alternative Communication (AAC) device, MyoVoice uses electrical signals recorded non-invasively from speech muscles (electromyographic, or EMG, signals) to restore communication for those with vocal impairments that resulted from surgical treatment of laryngeal and oropharyngeal cancers.
The bridging of the gap between speech production and perception by the interlocutor would be made possible by the use of a more suitable and automatic task. An acoustic-phonetic decoding test (or DAP in French, i.e. the production of isolated pseudo-words in repetition or reading), created within the framework of the The French National Cancer Institute (InCA) C2SI project, avoids the effects of cognitive restoration by the interlocutor. An automatic score from the DAP would lead to an overall score per patient, but also to scores specific to each phonetic segment, to be correlated with the analytical scores from each anatomical oropharyngeal segment. The study hypothesis is that the automatic processing of an acoustic-phonetic decoding task during the assessment in current practice is a valid and reliable tool for diagnosing oropharyngeal analytical and dynamic deficits by highlighting deficient linguistic units.

The main purpose of the study is to estimate speech intelligibility in noise. A Norwegian Hearing in Noise Test (HINT) for children will be implemented, and test results for normal hearing (NH) children and adults will be collected. Test results for groups of hearing aid (HA) users and test results for cochlea implant (CI) users will be collected and compared to the NH group and between groups of HA users and CI users. A group of single sided hearing loss patients will also be included. Binaural benefits of two ears, two HAs and two CIs will be estimated.
