Who is the voice of sonic Sonia and manic in sonic underground

Jaleel White. He voiced all three siblings, with mixed reaction. Some complain that Sonia sounds annoying and slightly odd, as White uses a falsetto voice. He also voiced Sonic in his other two shows, the Adventures of Sonic the Hedgehog (often abbreviated to AoStH) and Sonic the Hedgehog (alsoabbreviated this time to Sonic SatAM or just SatAM, due to it being aired early on Saturday mornings).
