In which form sound does convert, when one talk?

Answer 1

Having some difficulty understanding your question. However, on the guess you'd like to know something about the form of sound from the voice, here goes.

The voice is created by the larynx, which is a thin combination of muscle and tendon located in the throat. As we form words and air passes through a slit in the larynx, the muscles vibrate. The vibration causes the air passing through it to vibrate with compression waves.

Compression waves in the air are a bit like pressing quickly on a spring at one end and seeing the compression travel through the length of the spring to the other end. When these air waves hit our ear drums, they cause the ear drums to vibrate. That vibration is translated into nerve signals that go to the brain and are interpreted as voice sounds.

The speed of the voice sounds and all other sound through air depends a lot on the temperature of the air. But typical velocities are in the 500 mph or 1,000 kph ranges.
