When I listened to you read the second line you sound as if you are saying:

"Whoever is telling you that you are a selfish is just projecting their own selfishness on to you."

Maybe slow down a bit so that you can separate the words "you" and "are" so it does not sound like there's an extra word in between. Or when pronouncing "are" make sure to drag it out longer so it sounds like "Arr" not "Ah" or "Uh" like it does now.

When you read the third line the only issue you had was saying the word "down". The first line you read sounded perfectly fine, but then in this last line it sounded like you said "die in the dumps". I know you are able to pronounce "down" correctly so all I have to say in conclusion is to slow down a bit when speaking so you don't make a mistake. Focus on the pronounciation of the words rather than speed.

You are very good at speaking English! Other than these minor mistakes I understood you perfectly. Your voice is very clear.

Pronunciation Check

I'm a native Japanese speaker, so I'm trying to improve my pronunciation.
I've uploaded my pronunciation on Youtube. I've and read the material below three times as below.

<1> When it comes to love and partnerships, this year definitely goes down as the one to remember.
<2> Whoever is telling you that you are selfish, is just projecting their own selfishness on to you.
<3> I don't understand why you always take it out on me when you are down in the dumps.(We don't really use "down in the dumps" that much, you could say when you are upset or when your feeling angry)

If you find any mistakes or advice, please give me a positive feedback.
