Electrical energy
When a person speaks, mechanical energy is converted into sound energy. This is because the mechanical vibrations produced by the vocal cords travel through the air as sound waves, which can be heard by our ears.
Sound energy is used to make a person's voice louder. When a person speaks, the energy from their vocal cords creates sound waves that travel through the air and reach our ears, allowing us to perceive the sound as loud or soft.
The speed at which a person speaks is called their "speaking rate" or "speech rate." It is typically measured in words per minute (wpm).
A person who speaks without moving their lips is called a ventriloquist. They create the illusion that a puppet or dummy is talking by controlling their voice and facial expressions while appearing to be silent.
Sound consists of energy moving the molecules of a medium (air, water, rock), with a certain strength (amplitude) and vibration time (frequency). When a person speaks, the vibration from his voice pushes against the air molecules, which push against other air molecules, producing a widening wave front of molecular motion. The modulated energy of the vibration may eventually reach another person's ear. There the repeated impacts by the molecules are translated into nerve impulses, which the brain can interpret as vocal sounds. Because sound tends to spread out in all directions, there can be barriers directly between two people and yet one's voice may still be heard by the other.

Electrical energy in the form of a varying current. This then flows through a coil changing the magnetic pull on a metal diaphragm which then vibrates, and we are back to sound energy.
