Q: I want to make an app for disabled people. I want to make an app that uses text-to-speech and speech-to-text function. Text-to-speech has a robotic womens voice, so is it permissible for males to hear such a voice? Is it permissible for me to launch such app and sell.

Secondly, I want to make speech-to-text app for the deafs so that deaf can receive incoming calls, subtitles will appear, so is it permissible for me launch such an app? If any woman is calling, so her voice will be translated into text form. I think this background process will also be robotic. Is it permissible for me to launch such app?

Q: I previously purchased a playstore account with 7 more girls in university. Now I am starting my own android app business so I will buy my own separate playstore account as my intention is to sell features of my urdu learning app. There is some different process to put the app on the playstore for sale. So I want to make a separate test app to test the process of selling.

My question is, can I do this testing on the previously purchased playstore account which is owned by the 7 girls from university and myself. I will only do the testing for the selling process with the permission of the 7 other girls. If yes, do I need to share my profit with those 7 girls when I will be selling my app later on?

Note: I will not put my selling app on this account which is owned by the 7 other girls. I will only test the selling process.
