Masking release due to linguistic and phonetic dissimilarity between the target and masker speech. American Journal of Audiology, 22

Purpose: To investigate masking release for speech maskers
for linguistically and phonetically close (English and Dutch)
and distant (English and Mandarin) language pairs.
Method: Thirty-two monolingual speakers of English with
normal audiometric thresholds participated in the study. Data
are reported for an English sentence recognition task in
English and for Dutch and Mandarin competing speech
maskers (Experiment 1) and noise maskers (Experiment 2)
that were matched either to the long-term average speech
spectra or to the temporal modulations of the speech
maskers from Experiment 1.
Results: Listener performance increased as the target-tomasker
linguistic distance increased (English-in-English
< English-in-Dutch < English-in-Mandarin).
Conclusion: Spectral differences between maskers can
account for some, but not all, of the variation in performance
between maskers; however, temporal differences did not
seem to play a significant role.
