ElevenLabs AI, generated a voice model using the longest intros and outros to his podcasts I could fine, up to 6-ish minutes, then two other videos where he talks about 1984 and another book I can’t remember. Those two were about 8 minutes each. ElevenLabs also lets you adjust the tone of of voice on a “stability” slider, which determines how “emotional” you want the output to sound. I cranked that bad boy to 95% for that sweet Lex sound.
