you tube voice over bot

Hi i am into You tube, i am using my own voice for the videos, but i just came across some videos n which their is a female voice using bots , can any one suggest me where can i get those bot of female voice over for free.

I tried some apps in playstore but they are having some time limit.

https://acapela-box.com/AcaBox/index.php + audacity [https://sourceforge.net/projects/audacity/] to rip the audio free

if you want the premium app version you could try googling "[premium app name] free apk" and proceeding at your own risk...assuming you're on android device.

last option hire a voice over girl. fiverr has gigs $5 for 500 spoken words.
