我们调查了停止发声的可感知性在领域-最终中和上下文在德语中，根据各种音系模型是完全中和的，有利于不发音的类别，但根据各种经验研究是可区分的语音。一个主要的目的是确定是否声音线索，可用于停止发声区分是可察觉的在中和的情况下。第二个目的是评估发声感知是否受到语音定向频率和重音节可能性的影响。19名标准德语的听者对合成刺激物做出了强迫选择判断，这些刺激物跨越了发声-不发声连续体，在各种不同的语音配位概率和重音节可能性的中性语境中包含了域末肺泡和腭止音。我们的研究结果表明，语音信息是可以被区分的，但这种区分的可感知性也取决于音素序列的统计特性，以及是否可能在感知上将域末停顿重新音节化为域首停顿。我们的一般结论是，一个分类中和模型不足以解释在领域最终语境中德语的停止发声感知：相反，在这些语境中，发声感知依赖于声学信息和语音知识之间的相互作用，这是整个词汇的概括。2009爱思唯尔有限公司版权所有。
We investigated the perceptibility of stop voicing in a domain-final neutralizing context in German that according to various phonological models is completely neutralized in favour of the voiceless category but that according to various empirical studies is distinguishable phonetically. A primary aim was to determine whether acoustic cues that were available for the stop voicing distinction were perceptible in a neutralizing context. A secondary aim was to assess whether voicing perception was influenced by phonotactic frequency and the potential for resyllabification. Nineteen listeners of a Standard German speaking variety made forced-choice judgments to synthetic stimuli spanning a voiced-voiceless continuum containing domain-final alveolar and velar stops in various neutralizing contexts that differed in terms of phonotactic probability and the potential for resyllabification. Our results showed that voicing information could be distinguished but that the perceptibility of this distinction also depended on statistical properties of phoneme sequences and whether a domain-final stop could potentially be perceptually resyllabified as domain-initial. Our general conclusion is that a categorical neutralization model is insufficient to account for stop voicing perception in German in a domain-final context: instead, voicing perceptibility in these contexts depends on an interaction between acoustic information and phonological knowledge which emerges as a generalization across the lexicon.
