Gling's Accuracy and Miss Rate: What Silence-Based Detection Misses

Gling's detection is built around finding silence in the audio track, which means filler words spoken without a pause around them — a quick "um" folded into a sentence — often go uncut. The miss rate rises specifically on run-on speech, which is common in unscripted talking-head recordings.

Silence Detection vs Word Detection

There are two fundamentally different ways to find filler words. One approach scans the waveform for gaps in volume and assumes a filler word sits near a pause. The other approach transcribes what was actually said and flags specific words regardless of whether a pause happened around them.

Gling uses the first approach. It works reliably when speakers naturally pause around filler words — which happens often, but not always. The gap in accuracy shows up specifically when someone speaks quickly and folds an "um" or "like" into the middle of a sentence with no break in the audio at all.

Where This Shows Up in Practice

Recorded speech from professionals — consultants walking through a proposal, coaches delivering a lesson, sales reps running through a pitch — tends to be less scripted and more prone to run-on phrasing than podcast interviews with more measured pacing. That's exactly the pattern silence-based detection struggles with most.

What a Word-Level Check Looks Like

A tool that transcribes speech and matches specific filler words catches these regardless of pacing, because it isn't looking for a gap — it's looking for the word itself. That distinction matters most for people recording quickly, off-script, in a single take.

TrimTake's filler word removal is built on this word-level approach specifically to reduce the miss rate on run-on speech. See the fuller Gling comparison for a side-by-side on pricing and detection method.

How to Test It Yourself

Pick a recording where you know you spoke quickly and used filler words without clean pauses. Upload it and compare what gets flagged against what you'd expect a silence-only tool to catch. The gap is usually visible on the first pass.
