Mm-hmm.
and on top of that if we are having extra functionality people are willing to shell that twenty-five Euros money which we are thinking. Otherwise we are just like others in the market. So anyway that is the first , user interface could be of more than one type , and uh yeah that means we can do the on-line changes which which cannot be done now actually. So apart from the speech , we can have the scroll kind of thing with the buttons. Now for buttons , normal requirements like bit coding and all those things are required. And for voice , limited vocabulary automatic speech recognition system is required and we require a microphone also to be sitting there on the remote.
Yeah. That increases the the cost also.
Uh that's right. But uh means we have to see how much  what kind of microphones and stuff like that.
