论文摘要
在一个名为Gemma的项目中分析了所有受到颗粒，摩擦，液体，鼻腔和停止影响的意大利辅音，即摩擦，液体，液体，鼻腔和停止，该项目持续了大约25年。 Results of the analysis on stops, as published in (Esposito, A., and Di Benedetto, M. G. (1999). "Acoustic and Perceptual Study of Gemination in Italian Stops," The Journal of the Acoustical Society of America, ASA, Vol. 30, pp. 175-185) showed that the main acoustic cue to gemination in Italian was closure duration, while frequency and energy domain parameters were not significantly受到宝石的影响。本文 - 两个覆盖所有剩余辅音的一组中的第一个 - 介绍鼻和液体；它的同伴论文介绍了杂种和摩擦。鼻腔和液体的结果证实了停止的发现，特别是，意大利语中的主要声学提示本质上是持续时间，对应于辅音持续时间。结果还显示了辅音和前元素元素持续时间之间的逆相关性，但是，在考虑单胎与吉格纳特单词集合时也存在，这也存在，表明这些段之间的持续时间补偿以最终保留节奏结构。当考虑单胎和甲酸组合时，这种反相关将得到加强。 Singleton vs. Geminate辅音的分类测试表明，对于鼻腔和液体，当将辅音持续时间用作分类参数时，都可以获得最佳分类得分。尽管性能略低，但辅音和前元素元素持续时间之间的比率也是意大利语中Geminate与Singleton Nasals和液体自动分类的潜在良好候选者。
All Italian consonants affected by gemination, that is affricates, fricatives, liquids, nasals, and stops, were analyzed within a project named GEMMA that lasted over a span of about 25 years. Results of the analysis on stops, as published in (Esposito, A., and Di Benedetto, M. G. (1999). "Acoustic and Perceptual Study of Gemination in Italian Stops," The Journal of the Acoustical Society of America, ASA, Vol. 30, pp. 175-185) showed that the main acoustic cue to gemination in Italian was closure duration, while frequency and energy domain parameters were not significantly affected by gemination. This paper - the first of a set of two covering all remaining consonants - addresses nasals and liquids; its companion paper addresses affricates and fricatives. Results on nasals and liquids confirm the findings on stops, in particular that the primary acoustic cue to gemination in Italian is durational in nature and corresponds to a lengthened consonant duration. Results also show an inverse correlation between consonant and pre-consonant vowel durations which is, however, also present when considering singleton vs. geminate word sets separately, indicating a sort of duration compensation between these segments to eventually preserve rhythmical structures; this inverse correlation is reinforced when considering singleton and geminate sets combined. Classification tests of singleton vs. geminate consonants show that, for both nasals and liquids, best classification scores are obtained when consonant duration is used as a classification parameter. Although slightly less performing, the ratio between consonant and pre-consonant vowel durations is also a potential good candidate for automatic classification of geminate vs singleton nasals and liquids in Italian.
