Summary
This study shows that words, not morphemes, are key for understanding and producing Chinese speech. This finding impacts models of lexical access in natural language processing.
Area of Science:
- Psycholinguistics
- Computational Linguistics
- Chinese Language Studies
Background:
- Understanding lexical access in Chinese presents unique challenges due to its morphological structure.
- Previous models have debated whether the word or morpheme serves as the fundamental unit for processing.
Purpose of the Study:
- To describe Chinese speech comprehension and production processes.
- To demonstrate that the word, not the morpheme, functions as the Lexical Unit in Chinese natural speech.
Main Methods:
- Analysis of Chinese speech comprehension and production mechanisms.
- Theoretical argumentation against morpheme-based lexical access models.
Main Results:
- Evidence supports the word as the primary Lexical Unit in Chinese.
- Morpheme-based access models require improbable computational or processing assumptions for Chinese.
Conclusions:
- The word is the most plausible Lexical Unit for Chinese natural speech processing.
- Alternative models face significant theoretical and practical hurdles in explaining Chinese lexical access.
