speech cancellation device
i want to use the same technology used in ANC speakers with a little modification such that the device works with a cellphone but should be atleast 50 m away so that it can listen and cancel speech as you answer your phone such that nobody hears you. i have the idea and i would like you to develop the product for me then i will start selling it i am quite convinced it will make good fortune.
