Do people really say "ek-kitab" or do they say "ek'itab"?
In natural speech the final and initial क sounds merge into one and form a gemination. So yes, a native speaker would say "ekkitab".
This feature can be observed in all cases when two consecutive words end and begin with the same consonant.
Its is "ek kitab" only, it would never be "ekitab" , unless the person got some accent or some speech impairment.
And i am a native speaker.
This is very easy
WHERE IS THE AUDIO???
