<P> Mike Henry voices two of the show's main characters: Cleveland Brown and Rallo Tubbs . The voice of Cleveland was developed originally for Family Guy by Henry after being influenced by one of his best friends who had a very distinct regional accent . For the voice of Rallo, Henry has stated that he had originally created the voice over twenty years ago, when he had made a series of prank calls . </P> <P> Sanaa Lathan voices Donna Tubbs, the wife of Cleveland . In developing the character, Lathan said that the producers "wanted her to be educated, but to have some edge ." Prior to voicing Donna, Lathan had only one other voice credit in a relatively low - budget film entitled The Golden Blaze . In addition to the show, she also primarily worked as an actress in such films as Alien vs. Predator, Love & Basketball and The Family That Preys . </P> <P> Reagan Gomez - Preston plays Roberta Tubbs, the stepdaughter of Cleveland . Gomez has stated that she uses her own voice to portray Roberta, and that she herself gets mistaken for a fifteen - year - old over the phone "all the time ." Before Gomez was cast as Roberta, Nia Long (who co-starred with Lathan in The Best Man franchise) provided the character's voice during the first thirteen episodes . According to Long, she was replaced because producers decided they wanted an actress with a younger - sounding voice, given that the character is a teenager . </P> <P> Kevin Michael Richardson, a recurring guest voice on Family Guy and American Dad, portrays Cleveland, Jr., as well as Cleveland's next door neighbor Lester Krinklesac . In portraying Cleveland, Jr., Richardson drew inspiration from a character named Patrick that he had played on the NBC drama series ER who was mentally impaired and wore a football helmet . For Lester, Richardson stated in an interview that, being African American, he had "run into a few rednecks in (his) time," and decided to simply perform a stereotypical redneck impression for the voice of Lester . </P>
