Typical Yakuza stereotypes speak in a Kansai (Osaka/Kobe) or Chugoku (Hiroshima) dialect; when they do use Eastern Japanese, it's usually an extremely "rough" working-class Kanto dialect. This does bear some similarities to Goku's speech (chiefly in the monophthongization of vowel pairs), but is much more aggressive and vulgar (with things like trilled "r"s, colorful slang, and regular use of "temee" as a second-person pronoun). While I assume Tohoku yakuza exist, I'd have a hard time considering them threatening if they spoke with the dialect in fiction.
Goku's speech, in contrast, is relatively neutral Kanto dialect in vocabulary and even pronunciation, with the main things setting his speech apart being his use of "ora" as a first-person pronoun, "omee" as a second-person pronoun (though he often uses "omae" as well towards the start of the manga), and "yatsu" meaning "thing", as well as his assimilation of trailing "r" into the next consonant ("
Kekkon sukka?" comes to mind right away). These things are all marked (in contrast to Standard) as "rural" or "uneducated" speech, and "ora" in particular is a mark of people from the Tohoku region, which carries the "country bumpkin" stereotype.
By comparison, Chi-Chi and Gyumao speak in quite thick Tohoku dialect (or Toriyama's approximation thereof) in their first appearance; for Gyumao in particular, this has the effect of completely disarming him in the eyes of the reader, despite his considerable size and strength. When they reappear later on, however, their "Tohoku" speech has been whittled down to just a few key quirks (chiefly: monophthongized vowel pairs, use of particle "be", and use of "da" after verbs).
Regarding a question earlier in the thread, Beerus doesn't sound "just like Goku". His speech is unmarked Standard Japanese, with his defining traits being the use of "boku" (soft-masculine informal-polite) as a first-person pronoun, and "kimi" (soft/affectionate informal to equal or lesser status) as a second-person pronoun. He is also capable of using polite speech when required, though his default way of speaking is plain style (which, since he really does outrank everyone else in status, isn't really being rude).
