The emergence of cognitive vowel systems from articulatory-acoustic and perceptual vowel spaces.

拟议项目的总体目标是回答认知(语音)元音系统是如何在生理上给定的人类能力和发音产生和听觉语音感知的限制的基础上出现和演变的问题。在第一个应用阶段，我们将对德语中的声音对比进行全面的声学分析和感性评价，这些对比在不同的音系理论中被描述为长度对立、时差对比或音节切分差异。这将通过比较不同的德语标准变体，分析其元音系统内的持续变化，以及通过调查韵律因素的影响来完成。本程序旨在提出一套以语音为基础的特征，适用于解释德语已知的语音/音形限制，而不会遇到相互竞争的实际音系模型的问题(例如，在非重读音节中的长度中和，在[！]中缺乏音质差异Vs[！]，中和Short

The general goal of the proposed project is to answer the question how cognitive (phonological) vowel systems emerge ¿ and evolve ¿ on the basis of the physiologically given human capabilities and restrictions for articulatory speech production and auditory speech perception. During the first application period we will perform a thorough acoustic analysis and perceptual evaluation of the vocalic contrast in German that is described as length opposition, tense-lax contrast or difference in syllable cut in different phonological theories. This will be done by comparing different standard varieties of German and analyzing ongoing changes within their vowel systems as well as by investigating the influence of prosodic factors. This procedure aims at proposing a phonetically grounded set of features suited to explicate known phonological/phonotactic restrictions of German without running into the problems of the competing actual phonological models (with respect to e.g. length neutralization in unstressed syllables, lacking quality differences in [!] vs [! ], neutralization of short
