Reverberation degrades neural pitch coding far more for intonated than steady speech
Evidence
The interaction between reverberation and F0 modulation is further illustrated by plotting template contrast in response to modulated-F0 vowels against that in response to static-F0 vowels (Fig. 4 ). For both singleand double-vowel responses, the reduction in template contrast in the presence of reverberation is much greater in the modulated-F0 condition relative to the static-F0 condition — Dijk, Pim van, Physiology, Psychoacoustics and…, 5025
