This study investigates the perceptual role of several acoustic characteristics to glide generation processes affecting the consonants [t], [beta] and [eta], i.e., the vocalization of syllable-final [t] and syllable-initial [beta] into [w], and the insertion of [j] before syllable-final [eta]. Results from identification tests with synthetic speech stimuli performed on Catalan-speaking informants reveal that both the formant frequency characteristics (at the consonant steady-state period for [t] and [beta], and at the endpoint of the vowel transitions for [eta]), and the onset or onset/offset time of the vowel transitions may play an active role in vocalization and glide insertion. Mostly for the changes [t] > [w] and [eta]> [jeta], glide identification was triggered by formant frequency variations rather than by variations in the temporal implementation of the vowel transitions. The implications of the perception results for the interpretation of the sound changes of interest are evaluated.
本研究调查了几种声学特征在影响辅音[t]、[β]和[η]的滑音生成过程中的感知作用，即音节末尾的[t]和音节开头的[β]分别发成[w]的语音变化，以及在音节末尾的[η]之前插入[j]的现象。对加泰罗尼亚语使用者进行的合成语音刺激识别测试结果表明，共振峰频率特征（[t]和[β]在辅音稳态阶段，[η]在元音过渡终点处）以及元音过渡的起始或起始/偏移时间，可能在语音变化和滑音插入中发挥积极作用。主要对于[t]>[w]和[η]>[jeta]的变化，滑音识别是由共振峰频率变化触发的，而非元音过渡时间实施上的变化。文中评估了感知结果对于所关注语音变化解释的影响。
