 ## Improving diarization accuracy
 
-You can improve the accuracy of the diarization by providing the model with hints regarding the expected number or lower/upper bounds ofspeakers using the `diarization_config.num_of_speakers`, `diarization_config.min_speakers` and `diarization_config.max_speakers`  parameters respectively.

 **Important:** These parameters are hints, not hard constraints. The actual number of speakers detected by the model may not comply with the provided parameters.
