A superscriptLatin gammaU+02E0ˠMODIFIER LETTER SMALL GAMMA after the letter standing for the velarized consonant, as in ⟨tˠ⟩ (a velarized [t])
To distinguish velarization from a velar fricative release, ⟨ᵚ⟩ may be used instead of ⟨ˠ⟩
A superscript ⟨w⟩U+02B7ʷMODIFIER LETTER SMALL W indicates either simultaneous velarization and labialization, as in ⟨sʷ⟩ or ⟨pʷ⟩, or labialization of a velar consonant, as in ⟨kʷ⟩.
Although electropalatographic studies have shown that there is a continuum of possible degrees of velarization, the IPA does not specify any way to indicate degrees of velarization, as the difference has not been found to be contrastive in any language. However, the IPA convention of doubling diacritics to indicate a greater degree can be used: ⟨ˠˠ⟩.
