Based on Ganong's (1980) findings that English participants showed a significant lexical effect in phonetic perception, I hypothesize that there exists a difference in perception between real words and nonwords in TSM. The prediction is that the categorical boundary shifts as lexical status plays a role in perception of stops. Experiment 1 was conducted as a neutral set of perception of TSM bilabial stops b-p-p h. In experiment 2, cases of \"nonword-word-nonword\" set along the b-p-p h continuum were conducted. Results showed that real words corresponded to a wider range of VOT in the continuum compared to the neutral pattern. The categorical boundaries (both between /b/ and /p/ and between /p/ and /p h /) were found to shift away from the real word sides towards the nonword sides. The lexical effect may be explained by parallel processing in which a higher level of processing (lexical level) interacts with a lower level (phonemic level) in speech perception.", | |

| "text": "Categorical perception, which represents that sounds within a phonemic category are perceived as indistinguishable regardless of the correct identification of each sound, supports the modular view that speech is perceptually special. In literature, consonants were found to be perceived categorically, but not gradual; that is, although listeners were able to distinguish the consonant stimuli between different phonetic categories with ease, mostly they failed to distinguish the stimuli within categories. represents no delay in voicing; a negative VOT value refers to the phenomenon where the vocal fold vibrations begin before the articulatory release of the stop (the prevoiced [b] ). As VOT varies gradually, the identification changes abruptly from one stop to another. This categorical perception drives how the modular view regards speech-as a modular system. However, this raises an interesting question-is it modular in such a way that consonants are always perceived without the affection by other processing information?", | |

The model assumes that different levels of processing-features, phonemes, and words-are activated simultaneously during speech perception, which contradicts with the modularity view that phonemic processing in unaffected by higher levels of processing. Ganong (1980) investigated whether auditory word perception affected phonetic categorization. He constructed acoustic continua varying in voice onset time, each with an end being a real word and the other end a nonword (e.g., dash-tash vs. dask-task). The results showed a categorical boundary shift. Thus he argued that the lexical effect must arise at a processing stage sensitive to both lexical and auditory information.", | |

The present study examines a language of a three-way contrast in initial stops, Taiwan Southern Min, to see if there is a word superiority effect on speech perception. The prediction is that real words will correspond to a wider range of VOT in the continuum either comparing to the neutral pattern or to the nonword situation. The logic behind it is that listeners tend to perceive an ambiguous sound as a real word rather than a nonword. If the prediction is true, it should be found that the phoneme boundaries (both between /b/ and /p/ and between /p/ and /p h /) shift away from the real word sides towards the nonword sides.", | |

For instance, the difference between [b], [p] and [p h ] is due to voice onset time (VOT): the interval between the stop release and the beginning of vocal cord vibrations. A positive VOT value means such a lag exists (e.g. the aspirated [p h ]); a VOT value of zero" | |

Voice onset time (VOT) in msec of each syllable-initial stop was measured from the release of the stop closure to the beginning of the oscillating line which demonstrates voicing in the following vowel. These stimuli are adjusted from a TSM male speaker's natural speech. Among the 21 stimuli, all attributes of sounds are identical except the VOT in syllable initials." | |

For the pa line in the second graph, the location is outside the neutral solid line. In terms of the pha line in the third graph, it locates obviously at the right side of the neutral line. All of these consistent patterns suggest that there exists a lexical effect from the word pa53 \u98fd'full'-its lexical status affects the perception of consonants, making categorical boundaries shift towards the nonword sides." | |
