Perception of all English sounds in all preceding and following phonological environments ('English diphones data')

A common view in psycholinguistic models of spoken-word recognition is that speech decoding is essentially phonemic: the speech signal is mapped onto intermediate phonemic representations, which in turn are used to access phonemically coded lexical representations. Several types of evidence indicate, however, that acoustic-phonetic information is passed to the mental lexicon continuously, as it becomes available in the speech signal. This is not to say, however, that phonemes have no role to play in lexical access. The view that speech decoding is essentially phonemic captures the important fact that differences in the input which signal the intentions of speakers are phonemic. The process and representations involved in lexical access must thus be sensitive to phonemic differences. It is perhaps for this reason that psycholinguistic models of spoken-word recognition have assigned a greater role in lexical access to phonemic distinctions than to the continuous unfolding of phonemically relevant information.The aim of the present research was to provide temporally detailed perceptual data concerning the unfolding of phonetic information over time. For this purpose portions of natural utterances were presented to listeners for classification. To measure phoneme activations in all left and right phonetic contexts, gated versions of all possible English diphones were used.Stimuli sound files with final beep as presented to subjects (zipped, 231.58MB)Stimuli sound files without final beep (zipped, 227.6MB)Subjects' perceptual responses for the stimuli (WarnerMcQueenCutler_raw_data_gates_revised, 17.79MB)For additional information, see the README (english_README_2024_edit.pdf).<br><i>For inquiries regarding the contents of this dataset, please contact the Corresponding Author listed in the README.txt file.

在口语单词识别的心理语言学模型中，一个常见观点是语音解码本质上具有音位性：语音信号被映射到中间的音位表征（phonemic representations），而这些表征又被用于访问音位编码的词汇表征（lexical representations）。然而，多种证据表明，声学-语音信息（acoustic-phonetic information）会随着其在语音信号中变得可用而持续传递至心理词典（mental lexicon）。不过，这并不意味着音位在词汇访问中毫无作用。语音解码本质上具有音位性这一观点捕捉到了一个重要事实：输入中能够表明说话者意图的差异是音位性的。因此，词汇访问所涉及的过程和表征必须对音位差异敏感。或许正因如此，口语单词识别的心理语言学模型在词汇访问中赋予音位区分的作用，要大于音位相关信息的持续展开。

本研究旨在提供关于语音信息随时间展开的、时间细节丰富的感知数据。为此，我们向听者呈现自然话语的片段以进行分类。为了测量所有左右语音语境中的音位激活，我们使用了所有可能的英语双音素（diphones）的门控版本（gated versions）。
