The charts show the vowel and consonant systems of the East Franconian dialect in the 9th century. This is the dialect of the monastery of
Fulda, and specifically of the Old High German
Tatian. Dictionaries and grammars of OHG often use the spellings of the Tatian as a substitute for genuine standardised spellings, and these have the advantage of being recognizably close to the
Middle High German forms of words, particularly with respect to the consonants.
Vowels Old High German had six phonemic short vowels and five phonemic long vowels. Both occurred in stressed and unstressed syllables. In addition, there were six diphthongs. Notes: : All back vowels likely had front-vowel
allophones as a result of
umlaut. The front-vowel allophones likely became full phonemes in Middle High German. : The short close and mid vowels may have been articulated lower than their long counterparts as in Modern German. This cannot be established from written sources. : Vowel length was indicated in the manuscripts inconsistently (though modern handbooks are consistent). Vowel letter doubling, a
circumflex, or an
acute accent was generally used to indicate a long vowel. : In the Old High German period, there existed (possibly a close-mid vowel) from the umlaut of and the inherited . The former probably was not phonemicized until the end of the period. Manuscripts occasionally distinguish two sounds. Generally, modern grammars and dictionaries use for the open-mid vowel /ɛ/ and for the close-mid vowel /e/. : On the diphthongs’ origins: • OHG came from PWGmc

tōd Reduction of unstressed vowels By the mid 11th century the many different vowels found in unstressed syllables had almost all been
reduced to . Examples:
Consonants The main difference between Old High German and the
West Germanic dialects from which it developed is that the former underwent the
Second Sound Shift. The result of the sound change has been that the
consonantal system of
German is different from all other West Germanic languages, including
English and
Low German. The shift applied to different extents onto various dialects, added to other interdialectal variations, this makes a single "High German" system and precise articulations details thereabout difficult to reconstruct. Notes: :
Obstruents appeared in
fortis/lenis pairs. The realisation of this contrast probably varied across dialect. : changes to in all dialects during the 9th century. The status in the Old High German
Tatian (), as is reflected in modern Old High German dictionaries and glossaries, is that is found in initial position and in other positions. : was confined to Upper Alemanic and Bavarian varieties. : A
curly-tailed z is sometimes used in modern grammars and dictionaries to indicate the alveolar fricative that arose from
Common Germanic t in the
High German consonant shift. That distinguishes it from the alveolar affricate, which represented as
z. The distinction has no counterpart in the original manuscripts, except in the Old High German
Isidor, which uses
tz for the affricate. : It is not clear whether Old High German had acquired a palatalized allophone after front vowels, as is the case in Modern German. : The original Germanic fricative
s was in writing usually clearly distinguished from the younger fricative
z that evolved from the High German consonant shift. The sounds of both letters seem not to have merged before the 13th century. Since
s later came to be pronounced before other consonants (as in
Stein ,
Speer ,
Schmerz (original
smerz) or the southwestern pronunciation of words like
Ast ), it seems safe to assume that the actual pronunciation of Germanic
s was somewhere between and , most likely about , in all Old High German until late Middle High German. A word like
swaz , would thus never have been but rather , later (13th century) , . Old High German distinguished long and short consonants. Double-consonant spellings indicate not a preceding short vowel, as they do in Modern German, but true consonant
gemination. Double consonants found in Old High German include
pp, bb, tt, dd, ck (for ),
gg, ff, ss, zz, hh, mm, nn, ll, rr. Phonological developments This list has the sound changes that transformed
