Comment “Prompt” to get the detailed guide with all the prompts and resources. We tested 4 different AI video models to add dialogues to AI characters. Kling 2.6 Pro & Veo 3.1 did the job pretty well. Both the models added dialogues naturally with proper lip sync. It looked natural and matched expressions well. What’s clear is that AI models sync better when the audio has clean pacing and no background noise. You can also guide the model by mentioning the emotion or style you want - confident, calm, excited, anything. This small clarity improves the final output more than most people expect. --- Which model looked the most natural to you?
