We may aswell speculate that given the sufficient pitchtarget stability, the occurrence of speech <strong>to</strong> songillusion depends less on the <strong>to</strong>ne intervalstructure. Moreover, due <strong>to</strong> the listener’s ability<strong>to</strong> adjust perceived pitch in different tuningsystems <strong>to</strong> the ones we’re familiar with (such asinterpreting as well-tempered penta<strong>to</strong>nic scalewhen hearing a Sundanese Salandro scale by theWestern listeners), it is likely that the intervalstructure does not play a significant role in theillusion in the case of MC. Future perceptualexperiments is called for in determining the roleof interval structure as well as its complexmapping on<strong>to</strong> the <strong>to</strong>ne relations.V DiscussionIn conclusion, the current study confirms theTonal Hypothesis by Falk and Rethecke (2010),and the mechanisms in generating speech <strong>to</strong> songillusion in <strong>Mandarin</strong> <strong>Chinese</strong>. In the meantime,the current study does not negate the conclusionby Deutsch. First of all, we do have <strong>to</strong> take in<strong>to</strong>account part of the physical properties as a preconditionin generating the speech <strong>to</strong> songillusion; nonetheless, we do acknowledge thefact that the same input of the same physicalreality of the signal can generate different out putwhen repeated through the human perceptualsystem.There exists a long-standing notion of speech<strong>to</strong> song continuum by ethnomusicologistsanthropologists, who found in many culturesaround the world the existence of the vocalperforming genres that lie between speech andsong (or in some cases known as heightenedspeech). In the meantime, as illustrated in thispaper, what happens <strong>to</strong> speech perception whenrepeated signal is presented <strong>to</strong> human listenersdid not particularly attract scholar attentions untilrecently. Therefore the research in<strong>to</strong> speech <strong>to</strong>song illusion may offer us a new passage way <strong>to</strong>navigate the human audio-perceptual system andbrain modularity <strong>from</strong> speech <strong>to</strong> song.VI References[1] Deutsch, D., 1995.
