The male voice
Men’s vocal folds are approx 3mm longer than women’s regardless of their height or size. This allows many of them to have beefier bass baritone voices and more resonant timbre. Obviously tenors have higher, lighter voices but they still have a different quality of sound to women who can sing in this range.

The male voice also has a fantastic capacity for falsetto - a sound that is created by the vocal folds tilting and never coming together fully, but allowing for a space between them the whole time they resonate. This sound used by both Bach and the Bee Gees can be truly inspiring.
Male vocal issues tend to focus on monotony of tone, and insufficient breath (despite also breathing 24,400 times a day as women do). Feelings of flight and fight, adrenalin rush before speaking also afflict them.


The female voice
Women have shorter vocal folds than men which is why their voices are not so deep in tone and do not go as low. The way the cartilages of the male pharynx grow together accounts for the protruberence of the male adam’s apple which is not as pronounced in women although they also have a shield-shaped thyroid cartilage. We breath approximately 24,400 times a day – give or take. Thankfully we don’t have to remember to do it. The diaphragm works reflexively but breathing can also be a voluntary act – in other words most of the time we are on automatic pilot but if we want to take over the controls we can.

Women’s vocal issues tend to centre around breathy sound, lack of volume, sounding 'girly' and nerves. My belief is that good voice training releases your voice and you with it. It can allow your personality out of its box. Without being a therapy as such, it can help to disinhibit you and help you get rid of outgrown social constraints, increasing your self-confidence as a result and allowing for personal growth.
