Voice changer app during a call

(Thanks, Moderator)
In this age of AI, with several e-commerce websites such as Amazon.in, all avoiding Chats using a chat window, and emphasising on phone calls, our ‘voice’ samples need to be guarded against malevolent groups.

Else, our own voice phonemes could be extracted, then using an AI tool to create statements that aren’t spoken by us, be used against us.

I hope that the necessity for such an app would be understood.
