Perception of Speech in Context by Listeners With Healthy and Impaired Hearing

"The acoustic properties of speech sounds will be modified in two main ways. The first way is to introduce gradual changes to the perceived articulation of the target speech sound, such as changing from sh to s by various types of signal processing and filtering. The second type of change is to modify acoustic properties of the sounds that immediately precede the target speech sound, such as changing the speaking rate or its frequencies composition."
