Breathe through your belly
Belly breathing, also known as diaphragmatic breathing, helps you access a deeper pitch. This breathing style lets your diaphragm reach its lowest position, which helps slow down vocal cord frequency. Try standing straight, breathing in deep through your nose, and feeling your ribs expand.
So it tickled me to discover my voice was referenced in a recent dating study from the University of Sussex which found that men find a lower tone more attractive.
The deepness of a voice is primarily determined by the length and thickness of the vocal cords. Longer and thicker vocal cords produce lower, James Earl Jones-like pitches. So, if you want a deeper voice, you just need to thicken and lengthen your vocal cords.
Apart from anatomy, stress, anxiety, excitement (any emotion that causes us to move from baseline), causes our voice to increase in pitch. When people become frightened or excited, the muscles around the voice box (or larynx) unconsciously contract, putting strain on the vocal cords, making the pitch higher.
Before your growth spurt, your larynx is relatively small and your vocal cords are relatively thin. So your voice is high and kid-like.
If you want to change your voice without any external help, then you will need to put in some hard work and training. To change the pitch of your voice, you need to learn how to control the muscles in your vocal tract. They include the larynx, vocal cords, and lips.
The answer is yes absolutely. Some people can change their voices by simply becoming aware of their sound and then create a different sound. If you are told you're too soft (quiet) you might simply speak louder. If you're told you speak to quickly you might try to go slower.
Reasons people may speak in a quiet voice. A quiet voice may have a physical explanation. Many soft-spoken people will also tell you the issue is tied into feelings of shyness, poor self-confidence, and other psychological factors. A mix of the two is also common.
Puts' Scientific Reports study found that men with lower formant frequencies—a deeper resonance in their voices—tended to be taller, larger, and stronger. (That's partly because longer vocal tracts and larger vocal folds generate lower, more resonant voices.)
Testosterone will cause a thickening of the vocal chords, which will result in a more male-sounding voice. Not all trans men will experience a full deepening of the pitch of their voice with testosterone, however.
Puberty is a process of sexual maturation. A voice change is one of the secondary sexual characteristics adolescents develop. In boys, this happens between ages 12 and 16; in girls, between ages 10 and 14.
If you sound like a child, it is most likely that you are not using enough diaphragm support to release your singing voice in a relaxed mode; instead you constrict your throat more, in order to squeeze out your voice.
Taller people's lower airways are larger, allowing more room for vocal sounds to reverberate and create deeper-pitched tones. Not that this quality is exactly easy to hear.
Smoking can be a cause of voice change, specifically deepening and hoarseness. Voice change may indicate a need to follow up with your doctor. Two common causes of voice changes as a result of smoking include Reinke's edema and cancer of the vocal cords.
If you breath in helium (six times lighter than the air we breath), the pitch of your voice goes up. However, if you breath sulfur hexafluoride (six time heavier than normal air), your voice sounds low.
The most obvious difference between male and female voices is pitch -- what we perceive as a high or deep voice. Men, on average, speak almost an octave lower than women. And women (as we learn in the radio story above) tend to say the deeper, the better.
There is also abundant evidence that women prefer men with a deep voice, while men prefer women with a high voice. Attractive male voices are around 96 Hz and the most attractive women voices are up to 280 Hz.
Humming is one of the best all-around vocal exercises. This technique helps stretch the vocal cords, relaxes your facial muscles, and improves breathing. Humming also develops your vocal resonance and tone quality.
