On its own it's not correct in English. I have a permission form is ok but you can't say I have a permission
Ok so from a native speaker who is not a computer/IT whizz and has been speaking English for 51 years...
"I have a permit"
"I have /I've got a permit"
"I have/I've been given a permit"
" I have permission"
"I have /I've been given permission"
audio (fast) sounds like MAMY POZWOLENIE. Slow it is correct MAM ... Something wrong with the audio system?
"I have permission" - is this accepted
