Based on English VA's - I would prefer Sonic to sound closer to Jason Griffith. I always read Sonic's lines in Jason's voice. However, voices like Ryan Drummonds', Jaleel White's or Ben Schwartz's would work too! Roger Craig Smith's voice is a little deeper than how I would prefer Sonic to sound for this particular project! 

The world's fastest supersonic hedgehog sports an attitude and a sarcastic grin. When his tour of the world is interrupted by a call for help, he knows he has no choice but to return at breakneck speed. Evil deeds to Sonic are like a red rag to a bull, and when his friends are caught up in it, there's no holding back.
