+### Automatic Span Prediction
+Use PEAFrame to automatically detect time spans matching your text description:
+```bash
+python onnx_inference.py \
+    --audio input.wav \
+    --text "horn" \
+    --predict-spans \
+    --output separated.wav
+```
+
+This is ideal for long audio where you want to isolate sounds that appear intermittently. The model will automatically detect when the target sound occurs and focus on those segments.
+
+### Manual Anchors
+Specify exact time spans to focus on (positive anchors) or ignore (negative anchors):
+```bash
+# Focus on specific time ranges
+python onnx_inference.py \
+    --audio input.wav \
+    --text "person speaking" \
+    --anchor + 4.5 7.0 \
+    --anchor + 12.0 15.5 \
+    --output separated.wav
+
+# Ignore specific time ranges
+python onnx_inference.py \
+    --audio input.wav \
+    --text "background music" \
+    --anchor - 0.0 3.0 \
