Step 1: Upload an image.

Step 2: Enter a digital human speech script.

Step 3: Upload an audio clip (optional), customize the tone.

Step 4: Set the video duration.

After setting, click "Run" to get the Sonic digital human lip-syncing video effect.

Currently, the default settings are: 18-second video duration, 90-word speech script, and approximately 10 minutes of runtime.

If the video duration increases, the digital human speech script will also need to be longer, and the runtime will also increase accordingly.
