Training Procedure

The model was fine-tuned using:

Stitched long-form windows (~30 seconds)
Curriculum learning (high-quality IoU ≥ 0.9 data first)
Timestamp preservation (70/30 split)
Speaker grouping for natural speech patterns

Training Hyperparameters

Learning Rate: 1e-5
Batch Size: 8
Epochs: 3
Gradient Accumulation Steps: 4
FP16 Training: Yes
Warmup Steps: 500

Limitations and Bias

Optimized for Swiss German dialects
Best performance on meeting/parliamentary speech
May require domain adaptation for other audio types }
