요약Alternation patterns between sounds under certain conditions are widely attested in the history of various languages, and the development of German Umlaut is one of the best studied sound alternations that have their triggering condition shifted from phonological to morphological ones. In Germanic linguistics, the term Umlaut refers to the fronting process of certain vowels. It first occurs as a purely phonological alternation that is triggered by a following unstressed syllable containing i, i or j in Old High German (OHG). Since some suffixes of certain morphological categories start with unstressed syllables with i, i or j, there is an overlapping between the phonological and the morphological conditions, and when the phonological condition is obscured because of the dropping of j and the weakening of i, i to a schwa in Middle High German (MiHG), the Umlaut alternation becomes a pattern that is completely conditioned by the morphological categories of the umlauting forms.The research question of this dissertation is how the contributions phonological conditions and morphological conditions make to the general predictability of the Umlaut alternation change from OHG to MoHG. For this purpose, I conduct a quantitative investigation on OHG, MiHG and MoHG corpora with different regional varieties using two methods of measuring conditional entropy as quantification of predictability: the first one, developed from the practice in Ackerman et al. (2009) and Ackerman & Malouf (2013), is based on the distribution of Umlaut alternants across the corpora, and the second one uses the LSTM (Long short-term memory) model (Hochreiter and Schmidhuber 1996; Williams et al. 2020). I collect verb tokens with umlautable stem vowels from annotated corpora of OHG, MiHG and MoHG, and the conditional entropy of the Umlaut alternation is calculated under the distribution-based method and the LSTM model respectively and is compared with each other.There are two main findings in the results. On the one hand, the results see a decrease in the contribution of both phonological conditions and morphological conditions to the predictability of Umlaut alternation from OHG to MoHG, suggesting that the occurrence of the alternants becomes more and more lexicalized from OHG to MoHG. In other words, their occurrence tends to be lexically stored in the lexicon rather than derived based on the phonological or morphological context. On the other hand, the results of the LSTM model, which make use of all segments in the token as the phonological condition, show a remarkably greater contribution of phonological conditions to the general predictability in comparison to the contribution made by the quality of the vowel in the following syllable across OHG, MiHG and MoHG. It indicates that the Umlaut alternation, even in the period of MoHG where its degree of lexicalization reaches the highest point, is still conditioned by phonological factors beyond the quality of the vowel in the following syllable to a certain extent. This can serve as an evidence supporting the assumption of some phonological studies (Wiese 1996; Hansson and Wiese, to appear) that Umlaut alternation in MoHG is a phonological pattern with lexical conditions.
