Sound resumes after silence
Dr. Sergey Stepinov points out that extended periods of silence can alter the tone of the voice, leading to a decrease in its strength and quality. He explains that not speaking affects the voice's pitch and intensity because of its impact on the vocal cords, and causes the dysfunction of a part of the brain's cortex responsible for speech, as the nerve cells lose their connections. When the person resumes speaking, all the connections are restored, and their voice returns to its normal level.
