Jason Griffith
The person that voices Tails is a female named Amy Palant.
Jim Napolitano has: Played Additional Voices in "Hoshi no Kirby" in 2001. Played Additional Voices in "Shaman Kingu" in 2001. Performed in "Sonic X" in 2003. Played Additional Voices in "Sonic X" in 2003. Played Interviewee in "Puppet Rampage" in 2008.
He voiced him because he works for 4Kids, the company which dubbed Sonic X. When Deem Bristow died, the cast of Sonic X took over, much to the disappointment of fans. Since Griffith voiced Sonic in the anime, he now voices him in the games.
In the video games, Ryan Drummond was his first voice. Soon Jason Griffith made his voice. Now, Roger Craig Smith voices him. :)In the cartoons, Jaleel White voiced him in these shows: Adventures of Sonic the Hedgehog, Sonic the Hedgehog: The Animated Series, and Sonic Underground. Jason Griffith also voiced Sonic in Sonic X. Martin Burkevoiced Sonic in Sonic the Hedgehog: The Movie (OVA). So, we can tell here that Sonic has many voices so.......O.o that's all I have to say. Does that help?
