Finds filler words ("um", "uh") and stutters in speech for Clarity Sound Studio, a free, open-source macOS app. The app shows each detection for review and cuts the ones the user approves.

| File | `FillerDetector-v3.mlpackage`, version 3.1.0 (ML Program, FP16, macOS 14+) |
| Model | A 6.6 M-parameter Conformer over log-mel frames, with a small tree scorer (stored in the model's `fusion` metadata) that combines its output with the transcript |
| Training | From scratch on the AMI training split and the ICSI Meeting Corpus (128.5 h), with reverberation augmentation from OpenSLR SLR28 |
| Results | On the AMI test split (10.4 h, 2,805 fillers), counting a detection that overlaps a label: 85.1% precision, 83.0% recall |
