Hot! — Auto Lip Sync Blender Install

Do you have a (like Rigify or a custom mesh) that you're trying to set up right now?

While "Auto Lip Sync" could refer to a few different tools, most Blender users are looking for either the built-in method using "Bake Sound to F-Curves" or the popular Rhonda's Auto Lip Sync (or similar Python-based add-ons).

For a 3D character, this means selecting the appropriate Shape Key from a dropdown. For 2D, you'll select the corresponding Grease Pencil layer.

Prerequisites

: Need two characters talking to each other? You can simply create a separate controller for each character, assign them different audio sources (or the same one split by timing), and generate their performances independently.

After successful installation:

Since Blender does not have a single "official" Auto Lip Sync tool, this covers the that works with Blender 3.0+ to 4.2+.

If you need lip sync:

Once installed, workflow dictates reality. You load your audio into the VSE, select your rig’s phoneme shape keys (e.g., "AH," "E," "MBP"), and generate keyframes. The result is a rough first pass: technically synced but robotic. True artists use this as a foundation, not a final render. They manually tweak timing, add emotional blinks, and override mismatched vowels. Do you have a (like Rigify or a

Before running the analysis, your character needs to be ready. For a , you must have a set of Shape Keys (also known as blend shapes) that represent different mouth positions, or visemes. Ideally, you'll have keys for mouth shapes like "A," "B," "C," and so on. For a 2D character created with Grease Pencil, you should set up each mouth shape on a separate layer, such as viseme_A , viseme_B , etc..

LipKit simplifies lip-sync to a few intuitive steps.

For scenes with multiple characters speaking, LipKit's multi-character workflow is particularly useful. Create a separate controller for each character, assign different audio sources (or split the same audio by timing), and generate each independently. LipKit keeps everything organized with no keyframe clashes. For 2D, you'll select the corresponding Grease Pencil layer
