中文摘要 | 本研究旨在發展一份噪音背景辨識語音測驗。以年齡介於20至30歲之聽力正常年輕人為研究對象,樣本為三個部分:預測度分析12人、清晰度分析31人、複本測驗的發展30人。 測驗編製過程包括預測度分析、清晰度分析、語音與字詞熟悉度分析、信度分析與複本測驗的發展、效度分析等。研究結果摘述如下: 1.預測度分析:測驗中所有高預測度包子之預測度分數介於1至11分間,具有一定的預測度。 2.清晰度分析:採0 dB與-2 dB兩種信噪比,高預測度包子之清晰度為19或20分、低預測度句子的清晰度介於1到16分間、高低預測度句子之得分差距則介於3至19分之間。 3.語音成分分析:150個關鍵字音節結構均不重複,無論是300個句子或各表單50句子,其整體語音成分與國語語音成分都很接近。 4.熟悉度分析:150個關鍵字之口語出現頻次介於1至1300次之間,所有的關鍵字均為國小學童認識字並屬於常用字範圍。 5.測驗的信度分析與複本測驗的發展:本測驗共計發展了六張不同的表單,這六張表單在高預測度句子、低預測度句子及高低預測度句子得分差距之分數上,彼此相關程度很高,顯示這六張表單具有複本信度,亦說明六張表單復此互為複本。 6.效度分析:經預測度、清晰度、熟悉度與語音成分等幾項分析、並經專家審句子正低預測度句子兩項因素,顯示本測驗具有構念效度。而以驗證性因素分析檢驗六個表單互為複本的適合度,結果亦顯示六個表單彼此互為複本。 本研究並根據上述研究結果,提出未來研究方向的建議。 |
英文摘要 | The purpose of the study is to develop Mandarin speech Perception In Noise test. The participants of this study were normal hearing adults aged between 20 to 30. three groups of subjects were included to test the predictability (n=12), the intelligibility (n=31), and the equivalency (n=30) of the test lists. The development of the test includes several procedures: predictability analysis, intelligibility analysis, word familiarity check, phonetic analysis, reliability and validity data analyses. The results of the study were listed as follows. 1.The predictability scores of this battery is from 1 to 11. 2.The intelligibility scores of the high-predictability sentences are 19 or 20, low-predictability sentences are between 1 to 16, and the HP-LP difference scores are between 3 to 19. 3.There are 150 different key words. The phonetic content of the sentences is representative of utterances used by speakers of Mandarin. Each form has a similar phonetic profile. 4.The word frequencies of word familiarity for key words are between 1 to 1300. 5.All of the list fit the equivalence model for high-predictability, low-predictability and HP-LP difference scores. It was found that the test has alternate-forms reliability. 6.The test has content and construct validity. Confirmatory factory analysis was conducted. It shows that six forms are equivalent forms. Finally, there are some suggestions for the practical use and the future researches of the test. |
