Karagas vowels include two unique letters not found in Russian: Ö (front rounded O-vowel, like German schön) and Ÿ (close front rounded ü-vowel, like German über). Both unique vowels use diaeresis — the two-dot diacritic — in their written forms.
Karagas maintains Turkic vowel harmony — front vowels (Е, И, Ö, Ÿ, Э) and back vowels (А, О, У, Ы) appear in separate harmonic groups within words. The unique Karagas vowels Ö and Ÿ belong to the front-vowel class, paralleling their counterparts in other Turkic languages.
The Karagas consonant set includes Ң — the unique velar nasal ng-sound (as in "sing") — which is the distinctive consonant of Karagas Cyrillic not found in Russian. The remaining consonants are shared with standard Russian Cyrillic.
Karagas phonology features a prominent kh-sound (Х) characteristic of Sayan Turkic languages, and the ch-sound (Ч) and sh-sound (Ш) follow standard Turkic patterns. The language also has the zh-sound (Ж) primarily in loanwords from Russian.
The 3 pairs of unique letters in the Karagas Cyrillic alphabet: Ö/ö (front rounded O-vowel), Ÿ/ÿ (close front rounded ü-vowel, Y with diaeresis), and Ң/ң (velar nasal ng-sound).
The two diaeresis-vowels (Ö, Ÿ) are distinctive to the Karagas writing system — other Turkic Cyrillic alphabets use different forms for these sounds (e.g., Ө and Ү in Kyrgyz and Mongolian). The Karagas forms with diaeresis reflect a Soviet-era orthographic convention applied to Sayan Turkic languages.
Karagas uses Arabic numerals (0–9) in modern writing. The native Karagas (Tofa) number words: нол (0), бир (1), эки (2), ÿш (3), дöрт (4), беш (5), алды (6), чеди (7), сегис (8), тогус (9).
Karagas numbers illustrate the unique vowels: ÿш (three) uses Ÿ and дöрт (four) uses Ö. Note also чеди (seven) — a distinctive Sayan Turkic form, contrasting with yedi/жети in other Turkic languages — reflecting the phonological divergence of the Sayan branch.

The Karagas Cyrillic alphabet was standardised in the Soviet era to provide a written form for this oral language. The unique letters Ö and Ÿ (placed after О and У respectively) and Ң (placed after Н) follow the same organisational principle used in other Siberian Turkic Cyrillic alphabets.
