Auto lip sync tools analyze the amplitude, frequency, and rhythm of a voice-over track. They then convert that data into shape key values or bone rotations automatically. This allows you to spend your time on polishing expressions and emotional nuances rather than the mechanical opening and closing of a jaw.
Fix: Check your audio format. Most open-source lip-sync engines require uncompressed .wav files. If you are using an .mp3 or .ogg file, convert it to a 16-bit .wav file using a tool like Audacity before running the script.
Check your project's frame rate. If your audio file was recorded at a different timing baseline than your Blender timeline (e.g., 24fps vs 60fps), you may need to offset the generated keyframes manually in the Dope Sheet.

With the setup complete, you can now bake the audio directly into keyframes.
Depending on your character type (2D vs. 3D), different tools are more effective. Auto lip sync tools analyze the amplitude, frequency,

Double-check your Blender Preferences. Ensure the file path points directly to the actual application file ( .exe on Windows, or the binary executable on Mac/Linux), not just the folder it sits in. Fix: Check your audio format
