情深說話未曾講的英文版歌詞如下：
I've never spoken the words I felt most true
Yet the depth of my affection shows in my eyes
When I'm near you, I can't help but be shy
And so I keep my heart in front of my chest
情深說話未曾講
千言萬語都藏在心上
默默的陪伴 默默的守望
默默的想你到天亮
I've dreamed of these moments for so long
And now that they're here, I'm lost for words
I'm not one for making a big deal out of things
But I can't deny the way I feel inside
情深說話未曾講
我的心隨風飛向了遠方
想讓你聽見 愛你的旋律
卻害怕被你看穿我的慌張
以上是一個簡單的翻譯，歌詞的細節和情感可能需要根據歌曲的整體來進行更深入的解讀。
