Enhance Speech is Premiere Pro’s one-click AI dialogue cleanup. It lives in the Essential Sound panel, and on rough audio from a phone or a video call it can sound like a different recording. Pushed too far, it also makes voices sound processed, and every guide we found warns about that in some form.

This is synthesized from Adobe’s own description of the feature, several guides, and recurring reports in Adobe’s community forum, plus general Premiere Pro audio technique. Two of the guides come from companies that sell audio products (Hollyland makes microphones, and SimpleClean sells a noise cleanup service), so we’ve only used their technique advice. It isn’t a workflow we’ve tested end to end ourselves.

  1. Pick the right audio first. Adobe says Enhance Speech works best on dialogue from low-quality mics, like phones, online meetings, and on-camera mics, and is less effective on heavily degraded audio, overlapping speakers, whispers, loud music, and singing. One guide adds heavy room echo, strong wind, and clipped audio to that list. If your clip is one of those, expect a partial fix at best.

  2. Lock the cut before you enhance. Enhance Speech analyzes each clip, and in Adobe’s beta forum editors reported that trimming a clip after analysis triggered it again, which slowed editing down. Whether or not that’s still true in your version, cleaning up dialogue after the edit is settled saves waiting on analysis you’ll throw away.

  3. Tag the clip as Dialogue. Select the clip in the timeline (it doesn’t work from the Project panel), open Window > Essential Sound, and assign the Dialogue type. Enhance Speech only appears for Dialogue clips. If it’s grayed out, a missing tag or an outdated Premiere Pro is the most common reason.

  4. Turn it on and let it analyze. Enhance Speech is off by default. Check it and click Enhance. Analysis runs locally in the background, so you can keep editing while it finishes.

  5. Set the mix by ear, starting low. After processing, the Mix Amount slider blends the enhanced audio with the original. This is where the sources split. Some recommend keeping it low so a bit of natural room tone survives. Others say simply drag until it sounds best, with no target value. A third option, borrowed from general audio practice, skips blending entirely: run it fully enhanced, then lay a separately recorded room tone or ambience bed underneath. The common thread: a voice with zero background often sounds less real than one with a little. Toggle the checkbox on and off to compare.

  6. Listen to the pauses. The most consistent complaint in Adobe’s forum is words that come out robotic, garbled, or changed, especially around pauses and mumbled phrases. Play through every pause and quiet line before you move on. Lowering the mix usually helps; if one phrase is beyond saving, use the original audio for just that bit.

  7. Split clips that change. If the noise changes partway through a clip, like a door opening or an air conditioner kicking on, one guide suggests splitting it so each part can have its own setting instead of one compromise for both.

  8. Add targeted fixes afterward, one at a time. Both of the more detailed guides agree on order: Enhance Speech first as a broad pass, then only the Repair controls you still need, such as Reduce Rumble for low traffic or HVAC noise or DeHum for electrical buzz. Stacking a strong Enhance Speech with heavy Reduce Noise and Reduce Reverb is exactly what makes voices sound hollow or watery. EQ and compression come after the cleanup. If you have a usual chain, try it with and without Enhance Speech and trust your ears.

  9. Check it in context, on small speakers. Listen with the music and neighboring clips playing, then check on laptop speakers and earbuds, where most social video gets heard. Over-processing that’s hidden on studio headphones can be obvious on a phone.

Why it matters for designers

A lot of video now gets made by people who aren’t sound engineers, from a brand designer cutting a founder interview to a motion designer adding a voiceover recorded on a laptop. Enhance Speech is the fastest way to get that audio to a professional baseline without leaving Premiere Pro or learning a dedicated audio tool.

The skill isn’t finding the button. It’s knowing when to stop. The editors who are happiest with it treat it as a light first pass and judge the result by listening, not by a number on the slider.

What to watch out for

It reduces noise rather than removing it. Background noise and voices share the same frequencies, so pushing harder costs voice quality. If a recording truly needs a silent background, re-recording is still the real fix.

Forum reports from the beta period also describe exports that occasionally used unprocessed audio and sessions where the slider seemed to do nothing. The workarounds people describe are rendering the enhanced audio to a new file (or exporting the dialogue as a WAV and re-importing it) before the final export. Those reports are from 2023 and early 2024, so they may not apply to current versions, but it’s worth one listen to your exported file.

Enhance Speech is built for a single main speaker. On a panel or a crosstalk-heavy conversation, overlapping voices tend to give poor results.

Guides also disagree on the slider’s scale and on which version first included the AI feature, so ignore specific numbers you read elsewhere and go by what you hear in your own version.
