dictation problems in apple pay

Hi its Carlos,
I was trying to dictate my billing and mailing address in to apple pay.
When I use the dictation it lets me say my first name and sometimes my last name.
But when I try to dictate my address it makes the noice like I hit the home button or something like it and brings me back to the home screen.
Some times it has done that when I was trying to enter my last name as well.
it has happened in the billing and shipping address fields.
Has anyone encountered problems like this?
I spoke to the apple disability help desk and they cant duplicate the problem.
I have reset and even reinstalled ios 8.1.3 from iTunes with jaws on my computer but it still happens.
has anyone else had problems with dictation.
I'm using a new iphone 6.
Thanks
Carlos
