Speakers of different languages might rely on differential phonological units when planning spoken output. In the present experiment, we investigated the role of phonemes, as well as the relative time course of syllabic vs phonemic encoding, in Mandarin Chinese word production. A form preparation task was combined with encephalography (EEG). In Experiment 1, word-initial phonemic overlap was manipulated; in Experiment 2, overlap was either in terms of phonemes or of syllables. Priming in latencies was found for syllabic but not for phonemic overlap. Phonemic overlap modulated ERPs in a 230-300 ms time window (range across Experiment 1 and 2) whereas syllabic overlap was found in a 200-280 ms time window. These results show that both phonemes and syllables are important planning units for Chinese speakers, and the relatively similar time course of activation provides important constraints on psycholinguistic models of Chinese spoken production.

不同语言的使用者在规划口语输出时可能依赖于不同的语音单位。在本实验中，我们研究了音位以及音节与音位编码的相对时间进程在汉语单词产生中的作用。我们将形成准备任务与脑电图（EEG）相结合。在实验 1 中，我们操纵了单词起始的音位重叠；在实验 2 中，重叠要么是在音位方面，要么是在音节方面。我们发现，在 230-300ms 的时间窗口（跨越实验 1 和实验 2）中，音节重叠会引发潜伏期的启动，但音位重叠不会。在 200-280ms 的时间窗口中发现了音节重叠。这些结果表明，音位和音节对于汉语使用者来说都是重要的规划单位，而激活的相对相似时间进程为汉语口语产生的心理语言学模型提供了重要的限制。（143 个单词）。
