以往心理语言学研究的证据表明，音位单位，如音素在荷兰语和英语的语音规划（又名段检索假设）有特权的作用。然而，音节检索假设先前提出的普通话假设，只有整个音节单元（没有音调）可以预先准备在语音规划。本研究以广东话为例，探讨音节提取假说是否适用于其他汉语口语。在四个内隐启动（形式准备）实验中，参与者被要求学习各组提示-反应双音节词对，并在看到每个提示时说出相应的反应词。在一个块中的反应词是语音相关（同质）或不相关（异质）。当反应词具有相同的词首音节（不含声调）（实验1和4）或主体（实验3和4）时，受试者的命名反应在同质条件下显著快于异质条件下，但当反应词仅具有相同的词首音素（实验2）时，反应词的命名反应不显著快于异质条件下。此外，在音节相关条件下观察到的启动效应显著大于身体相关条件下的启动效应（Exp. 4）。虽然音节启动效应和词首音素的零效应符合音节提取假说，但粤语研究中获得的与身体相关的（亚音节）启动效应却不符合音节提取假说。这些结果表明，音节提取假说是不普遍的所有中国人的口语和音节和子音节成分是合法的规划单位在广东话的讲话产生。
Evidence from previous psycholinguistic research suggests that phonological units such as phonemes have a privileged role during phonological planning in Dutch and English (aka the segment-retrieval hypothesis). However, the syllable-retrieval hypothesis previously proposed for Mandarin assumes that only the entire syllable unit (without the tone) can be prepared in advance in speech planning. Using Cantonese Chinese as a test case, the present study was conducted to investigate whether the syllable-retrieval hypothesis can be applied to other Chinese spoken languages. In four implicit priming (form-preparation) experiments, participants were asked to learn various sets of prompt-response di-syllabic word pairs and to utter the corresponding response word upon seeing each prompt. The response words in a block were either phonologically related (homogeneous) or unrelated (heterogeneous). Participants' naming responses were significantly faster in the homogeneous than in the heterogeneous conditions when the response words shared the same word-initial syllable (without the tone) (Exps.1 and 4) or body (Exps.3 and 4), but not when they shared merely the same word-initial phoneme (Exp.2). Furthermore, the priming effect observed in the syllable-related condition was significantly larger than that in the body-related condition (Exp. 4). Although the observed syllable priming effects and the null effect of word-initial phoneme are consistent with the syllable-retrieval hypothesis, the body-related (sub-syllabic) priming effects obtained in this Cantonese study are not. These results suggest that the syllable-retrieval hypothesis is not generalizable to all Chinese spoken languages and that both syllable and sub-syllabic constituents are legitimate planning units in Cantonese speech production.
