Using an AI trained by Jar Jar’s lines to replace his dialogue seems a lot more respectable to Ahmed Best’s performance compared to throwing out his voice entirely. I don’t see much of an ethical issue here beyond just what comes standard with taking someone else’s work and recutting it to suit your taste. This also seems great for making edits that would stand up fine alongside canon media or others’ edits, since it can indeed be jarring going from a redubbed Jar Jar to the official voice.
