The voice is fading on the attack

Hello ! I am brand new to Cubase.

I started to record my voice but I’ve noticed that it is faded on the attack. Do you know how to cope with that?

Here is my voice recording (starts at 00:25).

I’m using Cubase Le with a PGA48 mic from Shure

Thanks for your help!

Disable any noise gate in the signal path, or adjust the necessary parameters correctly.
