Understanding how context affects speech perception in people with normal and impaired hearing

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This research investigates how adjacent sounds influence the recognition of speech in individuals with both healthy and impaired hearing. Participants will listen to manipulated speech sounds in a controlled environment and indicate what they perceive, allowing researchers to analyze the impact of various acoustic properties on speech recognition. The study aims to bridge gaps in previous research by examining speech perception in context rather than in isolation, potentially leading to improved hearing aid and cochlear implant designs. The methodology includes careful manipulation of sound frequencies and temporal properties to assess their effects on word identification.
