 ### VAD Parameter Fine Tuning
 
+#### **Classic way**
+
+**This is straightforward classic method `get_speech_ts` where tresholds (`trig_sum` and `neg_trig_sum`) are specified by users**
 - Among others, we provide several [utils](https://github.com/snakers4/silero-vad/blob/8b28767292b424e3e505c55f15cd3c4b91e4804b/utils.py#L52-L59) to simplify working with VAD;
 - We provide sensible basic hyper-parameters that work for us, but your case can be different;
 - `trig_sum` - overlapping windows are used for each audio chunk, trig sum defines average probability among those windows for switching into triggered state (speech state);

+#### **Adaptive way**
+
+**Adaptive algorythm (`get_speech_ts_adaptive`) automatically selects tresholds (`trig_sum` and `neg_trig_sum`) based on median speech probabilities over whole audio, SOME ARGUMENTS VARY FROM CLASSIC WAY FUNCTION ARGUMENTS**
+- `batch_size` - batch size to feed to silero VAD (default - `200`)
+- `step` - step size in samples, (default - `500`) (`num_samples_per_window` / `num_steps` from classic method)
+- `num_samples_per_window` -  number of samples in each window, our models were trained using `4000` samples (250 ms) per window, so this is preferable value (lesser values reduce [quality](https://github.com/snakers4/silero-vad/issues/2#issuecomment-750840434));
+- `min_speech_samples` - minimum speech chunk duration in samples (default - `10000`)
+- `min_silence_samples` - minimum silence duration in samples between to separate speech chunks (default - `4000`)
+- `speech_pad_samples` - widen speech by this amount of samples each side (default - `2000`)
