Dialects are a feature that was introduced in the DS remake of Dragon Quest IV, they showed a more cultural theme to each region in the game. For example, Burland (and its neighboring towns) had a Scottish dialect, Zamovska had a Russian dialect and Lassiez Fayre had a French dialect.

In each remake released for the Nintendo DS, Nintendo 3DS and Dragon Quest IX, dialects were added.

While many fans welcomed dialects as a nice addition to the series, others however disagreed with the use of dialects.
