Nobody but the reader can say whether your writer’s voice is “impressive” or worth listening to, but it’s still the only voice you have. Use your own voice instead of seeking to borrow another writer’s gaudy feathers.
Reading is so important in defining a writer’s voice. You may find a particular writer you love, who you read ravenously. You may even try to write like this writer. Trust me, all writers follow this pattern of idolization and emulation one way or another, and it’s part of what makes you a writer. While you shouldn’t consciously try to write like a writer you admire, reading him or her constantly will have a positive impact on how you write.
For example, I’ve absorbed the writings of George Orwell ever since I was about 16. He’s been a hero of mine, and also a stylistic guide. The clarity of his prose and the transparency of his voice, and most of all his humility, have inspired me for decades. While I haven’t intentionally tried to write like Orwell (that would be arrogant and foolhardy), I know he’s influenced me a great deal. I like the things that he liked: a simple, clear sentence and an attitude of wanting to engage readers through a stance of equality and democratic yearning.
I believe you find the writers you love during your youth, that you are already partially formed and predisposed to like this sort of writer. The key is to read widely and find the writers who connect with your predispositions. Once you do, read these writers voraciously. Try to analyze what it is that connects you to these writers. Is it the stories they tell or their personalities? Is it something stylistic, like the way the construct a sentence or paragraph or book? Finding the answers to these deeper questions will help you understand who you are as a writer and what you are meant to write.
Again, don’t purposely try to emulate another writer, but know that you will naturally and indirectly absorb what they have to offer. You will still be you, and will always have your own voice, but your reading experiences (and your life experiences) will shape your writerly sensibility. So, yes, your voice is always yours and can never be faked, but it can be broadened and deepened with reading and living experience.
A final bit of advice: try not to think about your writing voice too much. It’s sort of like a golfer thinking about the mechanics of a tee shot. The more you think about it, the worse it gets. Just write, knowing that your voice is coming out naturally. It’s already in there; just let it out.
