Girlfriend voice refers to the change in pitch or tone of a man's voice when talking to their significant other. The girlfriend voice is characterized by a higher pitch and a more effeminate tone with speech patterns scattered with pet names and childish words.

女友專用調(girlfriend voice)指男士在跟自己的另一半說話時聲調和語氣上的變化。這種變化主要體現為：聲調提高、語調更顯溫柔，并且不時夾雜著各種愛稱和幼稚的語言。

This type of speech is usually frowned upon when used in the presence of other men. When another man uses this voice they will usually receive a fair amount of ridicule.

有其他男士在場的情況下，這種語調通常會被嗤之以鼻。如果有男士用這種語調說話，經常會受到嘲諷。

For example:

Did you hear Bob's wicked girlfriend voice when he was talking to Lisa? Let’s give him some whip.

你聽見鮑勃跟麗薩說話時的那個腔調了嗎?咱們去教訓教訓他。
