The first word sounds very much like "Nhân" and no way like "Nhật". Maybe you should double check it?
This guy (voice talent) has this terrible habit when he starts speaking which is that he lengthens the first word for no reason. There are many sentences like this but I cannot do much except disabling the audio for those sentences.
Maybe you should consider someone who has an official accent to replace a northern accent "voice talent"
Not that far North. This "voice talent" guy can't distinguish between s/x, ch/tr, gi/d, etc., common problems with far north accent. Our standard accent is around Vinh (Nghệ An), a professor of mine was from Vinh and he can pronounce everything clearly!
This is correct. They sometimes add an "n" to make sentence flow. More noticeable here with use of "một". You hear this a lot in music.
You needed to write "the United States of America" per the drop down hints that are never wrong<sub>~</sub>~~
