According to one research, women prefer to talk in a higher-pitched voice than the males they adore. Take note of this tiny indication the next time you speak with her! Most older women utilize this body language technique to appear more desirable to a possible spouse. This is called the "vaginal tone" or "vocal fry." Older women tend to use this vocal habit because they lack the muscle control to produce tones lower than their male partners. They may even raise their voices to compete with other females for mating rights! This behavior is not intended as an insult but as a sign of affection. There are several reasons why older women speak with a higher pitch than their husbands or boyfriends. First of all, as they get older, their thyroid glands produce less testosterone-related hormone which results in them having softer voices. Also, as women age, their vocal cords become shorter which causes them to speak up louder than men of a similar age. This vocal trait is harmless and should not be taken negatively by the men around these beautiful women. On the contrary, it is another way for them to be noticed by their mates.
