Sound is generated in the larynx, and that is where pitch and volume are manipulated. The strength of exhalation from the lungs can affect the volume of the sound produced.
Fine manipulation of the larynx is used to generate a source sound with a particular pitch. This source sound is altered as it travels through the vocal tract, configured differently based on the position of the tongue, lips, mouth, and pharynx. The process of altering a source sound as it passes through the filter of the vocal tract creates the many different vowel and consonant sounds of the world's languages as well as tone, The larynx also has a similar function to the lungs in creating pressure differences required for sound production; a constricted larynx can be raised or lowered affecting the volume of the oral cavity.
The vocal folds can be held close together so that they vibrate. The muscles attached to the arytenoid cartilages control the degree of opening. Vocal fold length and tension can be controlled by rocking the thyroid cartilage forward and backward on the cricoid cartilage by manipulating the tension of the muscles within the vocal folds, and by moving the arytenoids forward or backward. This causes the pitch produced during phonation to rise or fall. In most males the vocal folds are longer and with a greater mass than most females' vocal folds, producing a lower pitch.

The vocal cords or larynx --
sound sources are a different type of music for example voice is one so a sound of source is anything that makes sound also there are lot's of different sound sources in this world
To be more specific, a sound source moving toward you will appear to emit a sound of higher frequency than actual. Conversely, a sound source moving away from you will appear to emit a sound of lower frequency than actual. See "the Doppler effect."
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.
Sound is generated in the larynx, and that is where pitch and volume are manipulated. The strength of expiration from the lungs also contributes to loudness. Fine manipulation of the larynx is used to generate a source sound with a particular fundamental frequency, or pitch. This source sound is altered as it travels through the vocal tract, configured differently based on the position of the tongue, lips, mouth, and pharynx. The process of altering a source sound as it passes through the filter of the vocal tract creates the many different vowel and consonant sounds of the world's languages as well as tone, certain realizations of stress and other types of linguistic prosody. The larynx also has a similar function as the lungs in creating pressure differences required for sound production; a constricted larynx can be raised or lowered affecting the volume of the oral cavity as necessary in glottalic consonants.
The vocal folds in the larynx are what cause the vibrations needed for producing speech. If a person's larynx has been removed or their vocal folds are paralyzed, then an external source of vibration is needed to produce the starting sound. Then all they have to do then is to mouth the words just like they did when they could speak.
your larynx or (voicebox)
capillaries
Your Larynx or "voicebox" creates the sound with which you speak. It controls the pitch and volume of your voice. The larynx also protects part of your trachea.
The larynx (or voice box) sits atop the windpipe (or trachea). If you make a sound and feel the vibrations in your neck, you are feeling your larynx at work.

You larynx
stridor
wheezes
It vibrates while you are speaking. For example, you exhale air while talking. This air passes over the larynx and the larynx vibrates which causes sound. You adjust the sound with your mouth, tongue and lips, so it sounds like words.
