You can vibrate your vocal cords by rhythmically pushing your belly to move air through them.
According to the provided YouTube video transcript, vibrating vocal cords involves controlled airflow:
- By rhythmically pushing the belly, you create a pulsating flow of air.
- This modulated airflow passes through the vocal cords.
- The interaction of the pulsating air with the vocal cords causes them to vibrate, creating a vibrating sound.
In essence, the coordinated movement of your belly muscles influences the airflow, which in turn causes your vocal cords to vibrate, resulting in sound production.
