Devoicing in the context of Voiceless

In historical linguistics, the High German consonant shift or second Germanic consonant shift is a phonological development (sound change) that took place in the southern parts of the West Germanic dialect continuum. The shift is used to distinguish High German from other continental West Germanic languages, namely Low Franconian (including standard Dutch) and Low German, which experienced no shift. The shift resulted in the affrication or spirantization of the West Germanic voiceless stop consonants /t/, /p/, and /k/, depending on position in a word. A related change, the devoicing of the voiced stopped consonants /d/, /b/ and /ɡ/, was less widespread, and only the devoicing of /d/ is found in most dialects.

There is no consensus on when the High German consonant shift occurred; it probably began between the 3rd and 5th centuries and was complete before the first written examples in Old High German, the earliest recorded stage of High German, were produced in the 8th century. There is also no consensus on where or how the shift proceeded.

Finno-Ugric transcription (FUT) or the Uralic Phonetic Alphabet (UPA) is a phonetic transcription or notational system used predominantly for the transcription and reconstruction of Uralic languages. It was first published in 1901 by Eemil Nestor Setälä, a Finnish linguist; it was somewhat modified in the 1970s.

FUT differs from the International Phonetic Alphabet (IPA) notation in several ways, notably in exploiting italics or boldface rather than using brackets to delimit text, in the use of small capitals for devoicing, and in more frequent use of diacritics to differentiate places of articulation.
