How does a person speak

All the people in the earth has abilities to speak, we do it every day without even thinking about it. Humans have evolved brains that process and create language and syntax, we also have flexibility in the mouth. humans can make a range of sounds and tones that we use to form thousands of words. Speaking happens when the air arrives from the lung. It goes through the vocal folds and outside the mouth. The lips, tongue and teeth forms the sound/noise to make the speech what the person wants to say. Most of the people that sings use their voices to create the instruments musics.
