There is said to have existed palatalization (i.e. {{IPA|[tʲ]}}, {{IPA|[dʲ]}}) among nearly all of the consonant sounds except for {{IPA|/j/}}, and possibly for {{IPA|/ʃ/}} and {{IPA|/ʒ/}}.{{r|Schmalstieg|p=26}}{{r|Dini|page=348}} Whether or not the palatalization was phonemic remains unclear.{{r|Rinkevicius|page=62}}

Apart from the palatalizations Proto-Baltic consonants were almost completely preserved. The only changes postulated are turning Proto-Baltic {{IPA|/ʃ, ʒ/}} into Prussian {{IPA|/s, z/}} and subsequently changing Proto-Baltic {{IPA|/sj/}} into {{IPA|/ʃ/}}.{{r|Rinkevicius|pages=61{{Hyphen}}62}}{{r|Dini|pages=348{{Hyphen}}349}}
