The Role Of Talker In Adjusting For Different Speaking Rates In Speech Perception, Chloe M Sharpe, Christian Stilp

Undergraduate Arts and Research Showcase

Speech perception is heavily influenced by acoustic context effects, where perception of a sound is influenced by acoustic properties of surrounding sounds. Talker variability, or the acoustic variability among different talkers, can disrupt these context effects. Studies have shown that talker variability does impact Spectral Contrast Effects (SCEs; an acoustic context effect induced by variations in frequency), but it is unknown if Temporal Contrast Effects (TCEs; an acoustic context effect induced by speech rate) are similarly affected. To test this, on each trial, listeners heard a context sentence (spoken at a fast or slow rate) followed by the target word …
