该研究以14000个美国电视新闻广播中的同音异义词为对象，发现其语音实现存在系统性差异，可通过语境含义预测，经时间归一化的语谱图是探查此类差异的优质工具。
AI 中文摘要
已知英语同音异义词的口语词长分布与使用频率存在共变关系。本研究探究同音异义词的其他语音实现方面是否也存在差异。对美国电视新闻广播中的14000个同音异义词实例开展的一系列定量研究显示，weight与wait等同音异义词对的实例具有不同的语音实现形式，且这些差异可由其在话语语境中的含义预测得出。即便考虑与时长相关的变异，这些系统性差异依然存在。经时间归一化的语谱图成为探查语音实现精细细节的极佳工具，且无需使用语音转写——语音转写必然会将语音真相隐藏于我们眼前。
英文摘要
The distribution of spoken word duration of English homophones is known to co-vary with frequency of use. This study investigates whether other aspects of the phonetic realization of homophones also differ. A series of quantitative investigations of 14,000 homophone tokens in American television news broadcasts revealed that the tokens of homophone pairs such as \textit{weight} and \textit{wait} have different phonetic realizations, and that these can be predicted from their meanings in utterance context. These systematic differences remain even when taking duration-related variation into account. Time-normalized spectrograms emerged as an excellent tool for probing the fine details of phonetic realization, and obviate the need for phonetic transcriptions, which inevitably hide the phonetic truth from our eyes.
