Regardless of what the book is about, my attention gets pulled to the voice of the reader.
So, I think audio books aren't really my thing.
ご質問ありがとうございます。
"Regardless of what the book is about,"=「本の内容にかかわらず」
"my attention gets pulled to the voice of the reader."=「読み上げている人の声に注意が行ってしまう。」
"So, I think audio books aren't really my thing."=「なので、オーディオブックはあまり私に合っていないみたい。」
