After the BD demo was released a portion of the forum at the time complained about the voices (some quite loudly), particularly for the DK. Larian went to the added expense (and time) to redo the voices for the full game, at which point another portion of the forum (many of whom were silent before) complained that they were better in the demo.
FWIW, the DK's voice work gets better as the game progresses.
Welcome to the forum.
