Probably not.
NO! Jason Griffith is currently voicing Sonikku
SEGA decided that it was time for a change, the change may have also occurred do to the bad fan reception from Griffith's time as voice actor.
Really, it depends on which show and games you're talking about. Like in the old freedom fighter sonic show, Jeleal White played the voice of sonic, but, in the new version in anime came out in 2007 on 4Kids tv Jason Griffith played his voice and also shadows. He also played the voice of both hedgehogs in Sonic Adventure, Sonic Adventure 2 Battle, Sonic hereos, Shadow the Hedgehog, Sonic Riders, Sonic the Hedgehog, Sonic Riders 2 Zero Gravity, and so on...
He didn't he got fired.

Jason Griffith, the same voice actor for Shadow the Hedgehog, Sonic the Hedgehog (2006), Sonic and the Secret Rings, and if you count the future title Sonic and the Black Night, that's Griffith too.

NO! Jason Griffith is currently voicing Sonikku
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?
