Résumé

The precedence effects to induce perceived spatial separation of target Chinese speech from informational or energetic maskers is discussed. The study also investigated the advantages of perceived spatial separation with two different sizes. The new approach used Chinese nonsense sentences as a speech signals and obtained results that are comparable to those reported from Freyman et al's study. The results show that advantage of perceived separation in releasing speeches from masking could extend to tonal Chinese which is not consistent with the prediction of two channel models.
