words. All typically voiced consonant sounds are voiceless. Stop sounds being , and fricatives as . Unlike Standard German, Swiss German does not have the allophone but is typically , with allophones . The typical Swiss shibboleth features this sound: ('kitchen cupboard'), pronounced . Most Swiss German dialects have gone through the Alemannic n-apocope, which has led to the loss of final -n in words such as 'garden' (standard German ) or 'to make' (standard German ). In some Highest Alemannic dialects, the n-apocope has also been effective in consonant clusters, for instance in 'horn' (High Alemannic ) or 'to think' (High Alemannic ). Only the Highest Alemannic dialects of the Lötschental and of the Haslital have preserved the -n. The phoneme is pronounced as an alveolar trill in many dialects, but some dialects, especially in the Northeast or in the Basel region, have a uvular trill , and other allophones resulting in fricatives and an approximant as [] like in many German varieties of Germany. In Bernese German, an [] can be pronounced as a []. It may also be pronounced this way when occurring towards the end of a syllable. A labiodental approximant is used in Bernese German, as the sound is present in Standard German. In Walser German, it is realized as a labiodental fricative []. Vowels Most Swiss German dialects have rounded front vowels, unlike other High German dialects. Only in Low Alemannic dialects of northwestern Switzerland (mainly Basel) and in Walliser dialects have rounded front vowels been unrounded. In Basel, rounding is being reintroduced because of the influence of other Swiss German dialects. Like Bavarian dialects, Swiss German dialects have preserved the opening diphthongs of Middle High German: : in 'lovely' (standard German but pronounced ); 'hat' (standard German ); 'cool' (Standard German ). Some diphthongs have become unrounded in several dialects. In the Zürich dialect, short pronunciations of // are realized as []. Sounds like the monophthong can frequently become unrounded to among many speakers of the Zürich dialect. Vowels such as a centralized [] and an open-mid [] only occur in the Bernese dialect. Like in Low German, most Swiss German dialects have preserved the old West-Germanic monophthongs : 'arrow' (Standard German ); 'belly' (Standard German ); 'pillar' (Standard German ). A few Alpine dialects show diphthongization, like in Standard German, especially some dialects of Unterwalden and Schanfigg (Graubünden) and the dialect of
