Abstract
Recent work has found that neural oscillators entrain with envelope modulations of attended speech in noise, and that speakers produce more pronounced amplitude modulations in noisy conditions. This study aims to expand on this finding, and to investigate how speakers adapt to temporal fluctuations in masking noise. 16 adult female participants were recorded reading sentences to a partner who repeated back what they heard while both were in quiet, in speech-shaped noise (SSN), and in SSN modulated by 1Hz, 4Hz, or 8Hz square waves. The amplitude modulation spectra for speech produced each condition were calculated. More pronounced modulations were produced in noise, with most similar effects for the 1Hz and SSN conditions. This suggests that changes in amplitude modulations are adaptations to the specific environment rather than a generalised response to noise, and that adaptations are not simply a function of the energetic content of the masker.
