how to change audio clarity

About   Windows/Workspace/audio/audio dialogue/clarity/dynamic : it seems to be working for me.

But if you know other method inside Premiere Pro to increase clarity, please share.

In Premiere Pro Windows/Workspace/Audio, I have found these settings for the "audio dialogue" :

At the red line in the screenshot you can see "Clarity" and a setting for "dynamique". 

Do you think it is a good thing to use "clarity" and "dynamique" in order to increase audio clarity of the video ?

Or do you know a better way to do it inside Premiere Pro ?

In fact, my goal is to work on an MP4 file (by increasing the audio clarity).

The Adobe "enhance speech" site works only on an audio file.

Unfortunately I have not Adobe Audition, but only Adobe Premiere Pro (as a single app).

In fact, in a video, my goal is to increase the clarity of the voice. How to do it ?

Try cutting the clip and add the Denoise Effect.
