To install and use auto lip sync in Blender, you can use the built-in add-on or external tools like Rhubarb Lip Sync. Option 1: Using the Built-in Blender Add-on
This is the most "plug-and-play" way to get it working via an external script. You typically find the file from repositories like GitHub or Blender Market. Installation: Open Blender and go to Edit > Preferences > Add-ons
Slightly open mouth with rounded lips (for vowels like AO, OW). F: Puckered lips (for vowels like UW, OW). G: Teeth touching lower lip (for F, V). H: Tongue pressed behind teeth (for L). X: Idle / Neutral expression.
Go to the official GitHub repository for the Blender Rhubarb LipSync add-on (created by Scaredyfeet or updated forks compatible with your Blender version). Download the .zip file. Do not unzip it. auto lip sync blender install
Installing and using the add-on is one of the best ways to speed up character animation in Blender. By automating the tedious task of keyframing mouth shapes, it allows artists to focus on performance and performance-driven animation rather than technical labor.
Integrates directly with Blender’s shape key system.
Integrating automated voice animation into your 3D workflow saves hundreds of hours of manual keyframing. Blender supports several powerful add-ons that automatically sync character mouth shapes (visemes) with audio files. To install and use auto lip sync in
Because Rhubarb is the most widely used free option, here is the step-by-step process to download, install, and connect the core tool to Blender. Step 1: Download the Required Files
The add-on will now appear in your (the right-side tab in the 3D Viewport). 2. Installing Third-Party Add-ons (e.g., Parrot or Rhubarb)
Before running any automated system, your 3D model must be prepared to receive the animation data. Automated tools cannot read raw geometry; they require designated targets. Shape Key Configuration Installation: Open Blender and go to Edit >
Slightly open mouth with relaxed teeth (for consonants like K, S, T). C: Open mouth (for vowels like EH, AE). D: Wide open mouth (for vowels like AA).
For specific workflows, such as 2D grease pencil animation or legacy versions, external tools are common.
The audio format is unsupported (e.g., heavy bitrate variable .mp3, .ogg, or encrypted formats).
