Well, sit back and relax, because I’m about to break it all down for you step-by-step!
What Options Does Kling AI Offer for Lip Syncing?
When using Kling AI Lip Sync, there are several options to consider that will allow you to create realistic dialogue for any avatar in a scene. So, let me sum them up before I get into the actual how-to steps:
Upload a Video for Lip-Syncing
With Kling AI, you aren’t solely limited to lip-syncing Kling AI-generated videos. You can freely upload any front-facing video of an avatar for lip-syncing. So, whether it is a video of a real person, animal, or animated avatar, the tool can match its mouth movements to the audio.

Generate Speech Audio via Script
If you don’t have an audio recording, then you can use Kling AI Lip Sync’s text-to-speech capabilities. With only English and Chinese languages supported, this option lets you input the text of what you want the avatar in your video to say.

Keep in mind that choosing this option means using an AI voiceover. There are different genders, professions, ages, etc, so you can just pick the one that best suits your avatar.
Use Your Own Audio File
With the ‘Upload Local Dubbing’ option, you can upload an audio recording of yourself or someone else for the avatar’s lip-synced speech. This is ideal if you prefer a more unique and personalized speech performance.
