Sound travels slower than light, and humans anticipate mouth shapes right before the sound is heard. In your timeline, grab all the generated lip-sync keyframes and slide them 1 to 2 frames backward . This makes the speech look significantly more natural.
To make a mouth move, your character model needs (also known as blend shapes).
Blender features a native tool that drives animations using the frequencies and volume of an audio file. While it does not detect specific spoken words, it is perfect for stylized characters, robots, or quick background animations. Step-by-Step Workflow

Even with automation, polishing the animation is key to realism.

The Ultimate Guide to Automatic Lip Sync in Blender Creating believable character animations requires accurate lip-syncing. Doing this manually by placing keyframes for every syllable is incredibly time-consuming. Fortunately, Blender offers several automated solutions to speed up your workflow.
Hover over the shape key value (0.0) and press to insert a blank keyframe. Open the Graph Editor window. Go to Channel > Bake Sound to F-Curves .

Creating realistic character animations can be incredibly time-consuming. Traditionally, synchronizing a 3D character’s mouth movements with an audio track—known as lip-syncing—required tedious, frame-by-frame manual keyframing.
Does not recognize specific words. The mouth simply opens wider when the audio is louder and closes when it is quiet. Basic Workflow for Baking Sound: Select your character's "Mouth Open" shape key.
Creating realistic character animations requires matching lip movements to spoken audio. Doing this manually frame-by-frame is tedious and time-consuming. Fortunately, Blender offers powerful automated solutions to streamline this process.
