Perception of lexical stress cued by low‑frequency pitch and insights into speech perception in noise for cochlear implant users and normal hearing adult
Purpose Cochlear implant (CI) users show great difficulty for understanding speech in noise and this fact may partly stem from their poor low-frequency (LF) pitch perception and temporal fine structure (TFS) processing. Clinical assessment of pitch perception is usually based on non-speech tasks. However, linguistically relevant contexts such as lexical stress may better reflect the role of pitch in speech perception, especially for everyday speech where background noise is inevitable.
