I`m currently developing an android application which is intend to call a user based on the user voice input. That is when user says a name (i.e "John"). i want to retrieve all the contacts from my contact list which contains that name with their contact number (i.e "John Mavel - +94715295296,John Cena - +94715295286, Marine Jone - +94715294568, Josh John Samuwel - +94715297895. etc"). And if there is only one contact with that name i want to make a call directly without giving any suggestions. By now i have implemented a code to make a call for a given hard coded name. and it takes a voice input.
