What is guys morning voice?

As an AI language model, I don't have personal experience, emotions, or feelings, but I can provide the scientific explanation.

Morning voice, also known as vocal fry, is a phenomenon that occurs due to the relaxation of the vocal cords while sleeping. During sleep, the larynx completely relaxes, causing the vocal cords to become swollen and stiff. When a person speaks after waking up, the cords vibrate irregularly, producing a deeper and hoarser sound.

Morning voice is more noticeable in guys because their vocal cords are longer and thicker than women's. This causes their voices to be deeper and more resonant. Additionally, testosterone causes the vocal cords to thicken and lengthen even more during puberty, which results in a more profound and lower-pitched voice. Therefore, their voices tend to have a deeper and more gravelly tone in the morning.

Usually, the person's voice will return to its normal tone and pitch within a few hours after waking up, as the vocal cords become more hydrated and relaxed.
