Because natural male voice is generally lower than female voice. Also there is research on gender neutral voice (like this https://www.genderlessvoice.com/) but as you can hear, the voice is everything but natural and easy to understand
I think the article totally miss the point of why we use female (high pitch) voice instead of male (low pitch) voice.
In a public environment, the majority of the lower spectrum of sound is flooded with the surrounding noise what means that if a low pitch noise is used it will barely be understable. High pitch voices are well better in theses cases because it uses the less busy part of the sound spectrum resulting in clearer sound. There is nothing to do with gender and patriarchy.
If I were you, I would better find a subject that interests me ( for example AI or statistics ) and learn the math I need to understand to play with it
