- voice activity detector (VAD) algorithm for splitting sound files
- Java Swing GUI for visualization, error analysis and editing
- group project for my MA programming course (Fall, 2015, Kobe University)
- editable hypo tier (green)
- non-editable target tier (dark blue)
- automatically updating eval tier (red) with VAD errors

| NDS(2) | noise detected as speech, arching 2 speech activities |
| FEC | front end clipping |
| REC | rear end clipping |
| HEAD | overhead: hypo starts before voice activity |
| TAIL | tail: hypo ends after voice activity ends |
The following FDA (more precisely Finite State Transducer) is implemented.
