Abstract
Speech segmentation is an important task in speech recognition in listening comprehension. It refers to the process of speech perception, in other words, recognizing individual word from continuous speech through segmenting the flow of words, which belongs to the micro level of listening comprehension. However, recently, there has been a deficiency in existing relevant research on the speech segmentation in domestic.
This study aims to look into the present situation of the application of speech segmentation in listening comprehension as well as the major factors that influence listeners’ performance in segmenting speech, in order to draw some implications that may be useful for the learning of English listening comprehension. The primary data are derived from an interview and listeners’ scores in one listening comprehension test, and three kinds of speech segmentation tests. Listeners’ scores are analyzed by SPSS 22.0 for Mac. The major findings are summarized as follows:
Through comparing the results of the tests, the high-score achievers have already shown a tendency in relying on stressed syllables to detect the onset of an independent word. They can also segment speech through the phonotactic features, and at the same time are influenced by lexical competition. By contrast, in accordance to low-score achievers’ behaviors in segmenting speech, the stressed syllables and weak syllables, as well as phonotactic alignment and misalignment are treated equally.
In view of the discussion of the results, this study discovers that the proficiency in using the stress-based speech segmentation strategy, the knowledge of phonotactic features of English and the effect of lexical competition in speech segmentation exert influence on listeners’ performances in speech segmentation, which can provide useful and significant clues, as well as support for segmenting speech, and further benefit listeners from successfully recognizing words from continuous speech in listening comprehension.
Based on the above findings, the researcher draws some implications that may be helpful for the improvement of English listening comprehension.
Key words: speech segmentation, listening comprehension, non-English majors
