One clip whispers, the next one shouts: the viewer keeps reaching for the volume. The fix is to bring every clip to the same level. Premiere Pro has two built-in ways to do it; a third turns it into one click.

Select the clips and press G (Clip › Audio Options › Audio Gain). Normalize All Peaks to brings the loudest point of each clip to the value you type; around -3 dB is common for speech.
This method looks at the peak. If a single cough or door slam raises the peak, that clip still ends up quiet; it does not measure loudness the way the ear hears it.
Select the clips, tag them as Dialogue in Window › Essential Sound and press Auto-Match in the Loudness section. Premiere measures the average loudness of each clip and pulls them all to the same target. The measurement is based on perceived loudness (LUFS), so it is more consistent than peak normalizing.
The Match loudness tool in Studio › Audio measures the loudness of the selected clips and brings them all to the target you choose. The target slider starts at -14 LUFS, a level widely used for social media and YouTube.
There is no single right answer, but there are common targets: around -14 LUFS for social media and YouTube, -23 LUFS for broadcast television in Europe. What matters is staying consistent through the video and keeping the loudest moment away from 0 dB.
For a quick tidy-up of a few clips, Audio Gain is enough. For consistent results on speech, Auto-Match is better. When you want to set the target yourself and protect the peaks, the third way fits.
